Product presentation
Prima Klima Whisperblower EC 150/160 – 1400 m³/h
THE Prima Klima Whisperblower EC 150/160 1400 m³/h This represents the pinnacle of extraction technology for serious indoor growers. This premium extraction fan embodies a decade of German-Czech innovation, combining cutting-edge engineering from the German manufacturer. EBM-Papst with the specialized horticultural expertise of Prima Klima.
The result? A ventilation system that offers impressive power 1400 m³/h while operating at surprisingly low noise levels — up to 2.5 times quieter than traditional AC fans.
This is not just a simple extractor fan: It is an integrated climate control system, designed for growers who require precise control of temperature, humidity, and air dynamics in their indoor growing spaces.
Understanding EC powertrains: why it's a paradigm shift
Technology EC (Electronically Commutated) in the heart of Prima Klima The EC 150/160 is fundamentally different from older AC motors. Unlike conventional asynchronous motors that operate in on/off mode, the EC motor is a direct current motor. without brushes, equipped with permanent magnets and integrated switched electronics.
How does EC technology work?
The EC motor in this model uses a technique called electronic switching. Instead of wearable mechanical brushes (as in traditional motors), the onboard electronics detect the rotor's position and automatically synchronize the current to optimize efficiency every nanosecond. This approach offers several critical advantages:
- Efficiency Superior energy efficiency: EBM-Papst EC motors achieve an efficiency of over 90%, against only 70-80% for conventional AC motors. For every kilowatt consumed, more air is actually moved — the rest is converted into minimal waste heat.
- Lifetime Wear-free switching: The absence of carbon brushes eliminates a component that wears out over time. The result: an expected lifespan of up to 12 years old, compared to 3-5 years typical of AC fans.
- Silence Quiet operation at all speeds: Unlike multi-speed AC motors, EC motors offer infinitely variable and silent speed control. No jerking, no annoying humming.
- Thermal Minimum heat generation: EC motors create less heat during rotation, which extends the life of internal components and improves conditions in your grow room — less heat means savings on air conditioning.
Technical specifications: what you actually get
| Setting | Value | Implications |
|---|---|---|
| Maximum flow rate | 1400 m³/h | Grow room capacity of 140-350 m³ depending on heat load |
| Flanges | Double 150/160 mm | Compatible with standard 150mm and 160mm ducting |
| Power consumption | 170 W | Extremely low consumption for this flow rate; energy savings achieved |
| Input voltage | 230V AC, 50/60 Hz | Compatible with Europe, Africa, and Asia; 1.4 A current |
| Maximum temperature | 50°C | Safe for mounting against heated filter housings |
| Dimensions | 334 x 367 mm (W x H) | Compact size allows for installation in small spaces |
| Net weight | 3.85 kg (5.50 kg packaged) | Easy transport and installation; no need for structural reinforcements |
| Pressure curve | 0-650 Pa | Capable of overcoming pressure drops in carbon filtration |
The flow rate of 1400 m³/h allows for complete air renewal in a ~233 m³ grow room (length 6m × width 5m × height 8m) in just 10 minutes — which corresponds to an air cycle of 6 complete changes per hour, a professional standard for aggressive ventilation.
Sizing tailored to your space: how to calculate your actual needs
One of the most common mistakes in indoor growing? Choosing a fan based solely on its nominal airflow. Growers forget that the actual airflow drops drastically once a carbon filter and ducting are added.
The practical formula for indoor growing
Step 1: Calculate the volume of your room
Volume = Length (m) × Width (m) × Usable Height (m)
Step 2: Determine your target ACH (Air Changes per Hour)
- Without CO₂ input: 40-60 changes/hour (aggressive ventilation, ideal for high humidity)
- With CO₂ injection (closed system): 10-20 changes/hour
- Recommended average for LED growing: 20-30 changes/hour
Step 3: Apply the load loss factor
Carbon filtering and ducting reduce your effective flow rate by 30-50%. If you are using a quality filter (4mm carbon granules): apply a reduction coefficient of 0.65, which means dividing the required flow rate by 0.65.
Concrete example
- Bedroom : 3m L × 4m L × 2.4m H = 28.8 m³
- Target purchase price: 20 (good balance for LED + humidity) = 28.8 × 20 = 576 m³/h gross
- With loss of charge: 576 ÷ 0.65 = 886 m³/h required
For this configuration, the Prima Klima EC 150/160 1400 m³/h would be excessive (a smaller model would be preferable). However, for a professional installation of 6m × 6m × 2.8m (100.8 m³), the EC 150/160 1400 m³/h offers just the required capacity.
Acoustic performance: the silence that changes everything
One of the major strengths of this model is its exceptional silence. Indoor growers near residential areas know this well: a noisy fan can quickly become a social or legal problem.
Measured noise data
The Whisperblower EC 150/160 technical brochure provides sound pressure level measurements in decibels (dB) at various flow rates. While the complete specification is not detailed in the provided leaflet, the 150/160 EC models offer a sound pressure level reduction factor of 2.5 times less noise compared to equivalent AC fans.

Integration into a cultivation facility: complete system architecture
Standard Extraction Setup for Pro
THE Prima Klima EC 150/160 1400 m³/h is a central hub solution that connects to three essential elements:
- Activated carbon filter (upstream)
Most installations place the filter before the fan. The filter must have a flow rate capacity equal to or greater than that of the fan. For this model, a 150-160mm filter with a carbon surface area >1200 m²/g (like the high-activation CTC75 used by Prima Klima) is recommended. This type of filter has a moderate pressure drop (~100-150 Pa at nominal flow rate) and a lifespan of 6-12 months depending on relative humidity and flow rate. - Ducting sheaths (150/160 mm)
Use food-grade flexible or rigid tubing (Combidec 2000: polyester + aluminum, 5 layers, heat resistant). Tubing bends and lengths increase pressure drop: each 90° bend adds ~30-50 Pa. - Extraction point (outside or towards the outside)
The duct must vent the saturated air to the outside. A non-return valve should be installed to prevent cold air from returning if the fan stops.
Directional airflow: Push vs. Pull
Prima Klima recommends a suction extraction configuration (the fan "pulls" air through the filter). This provides:
- Improved engine protection (filtered air cools the coils)
- Preventing dust deposits on the engine
- More stable flow rate even as the filter ages
Reverse configuration (fan pushes air): reserved for small installations or pure blowing.
Control selection: 3 levels of climate sophistication
Prima Klima offers three versions of the EC 150/160:
| Model | Control | Use Cases | Key advantage |
|---|---|---|---|
| PK150/160WHSP-A | Monolithic (fixed speed) | Basic installation, single flow rate | Reduced cost, maximum reliability |
| PK150/160WHSP-EC | Electronic dimmer 0-10V | Manual speed selection | Flexible energy savings, reduced noise under partial load |
| PK150/160WHSP-ECTC | Onboard thermocontroller | Automatic temperature regulation | This one is the "pro-grade": it works on its own without external equipment |
The ECTC model: autonomous climate brain
The EC-TC model incorporates an analog thermostat that automatically reduces the fan speed if the temperature drops. Imagine:
- Starting threshold: 26°C (example)
- You set a hysteresis of +2°C
- The fan runs at 100% up to 28°C
- It gradually decreases to between 26-28°C
- It stops if the temperature is below 26°C.
This represents a significant electricity saving: instead of running 24/7 at full power, the speed adjusts. In an environment where nighttime cooling is less critical (low external temperature), this can reduce consumption by 30-50%.
Energy efficiency and ROI calculation
Actual consumption vs. other technologies
THE Prima Klima EC 150/160 consumes 170 W at nominal flow rate (1400 m³/h). Let's break this down:
- Equivalent traditional AC fan: ~280-320 W to achieve 1400 m³/h
- EC efficiency gain: 170/300 = 56.7% energy savings for the same flow rate
Annual economic calculation (Europe, average price €0.18/kWh, 18 hours/day usage)
| Technology | Power | Annual consumption | Annual cost | EC savings/year |
|---|---|---|---|---|
| AC standard | 300 W | 1.971 kWh | €354 | — |
| Prima Klima EC 150/160 | 170 W | 1.120 kWh | €201 | €153 (43%) |
Over an average lifespan of 7 years: approximately €1,070 saved on the electricity bill alone. The initial extra cost of an EC (approximately €200-€300 more than a standard AC) is recouped within 2-3 years of use.
Indoor humidity and CO₂ management: why adequate extraction is critical
The physiological role of the ventilator in growth
A novice grower might think that the fan is just there to "remove the heat." It's much more nuanced than that:
- Removal of saturated moisture: Plants release 95% of the water they absorb through transpiration (a phenomenon known as "evapotranspiration"). In a closed room without ventilation, the relative humidity quickly rises to 95%+ → ideal conditions for mold (botrytis, powdery mildew) and root rot. Prima Klima EC 1400 m³/h renews the air sufficiently to maintain an optimal RH (50-70% during flowering).
- CO₂ renewal: Plants consume CO₂ for photosynthesis. Without air exchange, the concentration drops from 400 ppm (atmospheric standard) to <200 ppm in a few hours, halting growth. Robust extraction naturally introduces fresh CO₂.
- Circulation of gaseous nutrients: Ethylene (the maturation hormone) accumulates around plants. Insufficient air circulation causes growth deformities (stretching, leaf drop). The movement created by a good extractor fan forces the plant to strengthen its tissues.
- Prevention of localized hotspots: Grow lights (LED, HPS) create microclimates. Rapid extraction homogenizes temperature and humidity, preventing heat stress.
For an installation of 150-200m³, the Prima Klima EC 1400 m³/h is ample, allowing 8-9 complete air changes per hour — beyond professional standards.
Convenient installation and integration in your home
Anchor points and fixing
THE Prima Klima The EC 150/160 comes with a wall/ceiling mounting bracket. Its net weight of 3.85 kg (5.5 kg packaged) ensures stable installation even in vertical configurations.
Installation steps
- Filter preparation: Connect the carbon filter to the angled connector of the fan using the supplied metal hose clamp.
- Suspension: Attach via the bracket to a load point (rafter, rail). Preferably, a suspended mounting at the top rather than on the floor (better airflow, no moisture buildup).
- Extraction duct: Connect the outlet duct to the venting point (window, wall hole, roof). Use metal clamps (jubilees) every 60-80 cm.
- Power supply: Connect to 230V via dedicated socket; ideally with a 16A circuit breaker.
- Order : If EC-TC version, set the thermostat to a temperature probe positioned in the center of the growing area (neither too high = concentrated hot air, nor too low = minimum temperature).
Installation acoustic considerations
- Vibration isolation: Place vibration dampers (rubber/neoprene) between the console and its wall mount.
- Flexible sheaths: Use flexible ducting rather than rigid ducting — turbulent air in rigid ducting generates more noise.
- Inline muffler (optional): For installations that are extremely sensitive to noise, add an in-line silencer (additional reduction of 8-12 dB, very low flow loss).
Maintenance and longevity
Preventive maintenance
Unlike AC motors with brushes (which require replacement every 2-3 years), the EC 150/160 is virtually maintenance-free:
- No brushes to replace → Zero internal maintenance
- Filter: Replace every 6-12 months depending on usage (visually check: blackening = end of life)
- Sheaths: Clean every 2-3 months (dust/residue accumulates)
- TC probe (if applicable): Check every 6 months that it is responding correctly
Advertised lifespan: 12 years
This is the expected lifespan of the EC EBM-Papst motor under normal conditions (temperature <50°C, no flooding, normal start/stop cycles). With basic maintenance, exceeding 12 years is common.

Frequently asked questions by farmers
A: Technically yes, but it's inefficient. For small rooms (<20 m³), opt for the PK125 (max 530 m³/h). The EC 1400 will excel in spaces >100 m³. However, its EC-TC variant allows for intelligent speed reduction—even in small spaces, it can run slowly, hence its appeal.
A: Purchase a 150mm or 160mm filter with a capacity of ≥1400 m³/h. Opt for 4mm pellets (fine granules) rather than powder — better balance between performance and pressure drop. Filters Prima Klima Combidec specified at 1400+ m³/h are optimal.
A: No. Unlike multi-speed AC fans that make noise when switching between speeds, EC fans offer continuous and silent reduction. At 50% speed (700 m³/h), the noise level is approximately 45 dB (similar to the sound of a low-volume conversation).
A: You can, but it will deplete your room of CO₂ if it's not sealed. Ideally, combine the exhaust with a controlled fresh air intake (partially open window, independent supply ductwork). Otherwise, you're wasting injected CO₂.
A: Estimate: Carbon filter (~100 Pa drop) + 5m duct (~80 Pa) = total ~180 Pa resistance. Looking at the pressure curve of the EC 150/160, at 180 Pa, the fan delivers approximately 1200 m³/h effective airflow — a 14% reduction is acceptable and justifies this choice rather than a smaller one.
A: Yes, it's designed for that. However, running it 24/7 accelerates filter wear and increases your electricity bill. Better yet: install a timer or thermostat (TC version) for optimal operation (18-20 hours/day on average).
A: 230V cable supplied. Connect to a dedicated 16A circuit breaker. Not suitable for three-phase configuration. The EC-TC version can be controlled via a temperature probe (wired, minimum 1m), or an external dimmer (0-10V if needed in the future).

Question about the Prima Klima WHSP EC 150-160mm extractor: In the context of indoor cultivation with several varieties having different ventilation needs, does this model allow for precise adjustment of the air flow to optimize air exchange without hindering the development of plants sensitive to mechanical stress?
The Prima Klima WHSP EC Ø150/160 mm extractor is designed to be quiet, helping to minimize mechanical stress on plants. However, this model does not feature an integrated precise airflow adjustment. For crops with very specific ventilation needs, external flow control or a variator may be necessary to finely adjust the extraction intensity.
If you are looking for a solution with dynamic adjustment capability and quiet operation, models like the Whisperblower EC-TC offer better modulation due to their efficient EC motor, with optimized pressure and noise.
In summary, the Prima Klima WHSP EC is an excellent base, but for very precise control, an additional control system is recommended.
Does the EC motor allow speed control to adjust the air flow according to the size of my compact growing room?
The EC motor of the Prima Klima WHSP EC Ø150/160mm Extractor, with a flow rate of up to 1400 m³/h, indeed allows for precise speed control. This electronic technology gives you the option to adjust the air flow according to the size of your compact growing room, ensuring optimal and energy-efficient ventilation while maintaining quiet operation.
Can the Prima Klima WHSP EC 150 160mm silent extractor be effectively used in a 60x60 micro-culture without disturbing the ambient silence?
The Prima Klima WHSP EC - Ø150/160mm extractor is known for its silent operation thanks to its EC motor, which reduces noise and energy consumption. With a capacity of up to 1400 m³/h, it provides very powerful ventilation, probably too much for a 60x60 cm micro-culture.
However, thanks to its digital controller, it is possible to finely adjust the fan speed between 0 and 100%, allowing you to adapt the air flow to the specific needs and thus limit the noise. By setting the flow to a moderate level, this extractor can be used effectively without disturbing the ambient calm of your micro-culture.
For such a small space, it might be worthwhile to consider an extractor with an appropriately sized capacity to avoid over-sizing, but your choice remains very efficient and quiet if well adjusted.
Can this model maintain a constant optimal flow rate between 1200 and 1400 m³/h without significantly increasing electrical consumption or generating excessive noise?
The Prima Klima WHSP EC Ø150/160mm extractor is equipped with a high-end EC motor that allows for maintaining a constant flow rate between 1200 and 1400 m³/h thanks to precise speed control. Its consumption remains moderate, around 170 W, even at high speeds, due to the energy efficiency of EC technology.
Moreover, this model is designed to be quiet: its motor does not produce rumbling, and the structure optimizes airflow management, limiting noise. It is therefore perfectly suited for powerful, stable, and discreet extraction within the desired flow range.
What is the actual noise level of the Prima Klima WHSP EC extractor at 1400m³/h, and can it be easily regulated to adjust the ventilation based on the size of the growing room?
The exact noise level of the Prima Klima WHSP EC extractor Ø150/160mm at its maximum flow rate of 1400 m³/h is not officially specified, but it is universally recognized for its very quiet operation thanks to its EC motor and optimized design that significantly reduces noise compared to traditional extractors.
Regarding regulation, this extractor generally features an integrated or optional speed control system, allowing for easy adjustment of the airflow based on the size of your growing space, thus providing perfectly tailored ventilation to your needs.
What is the difference between the maximum flow rate of 1400m³/h stated in the title and the flow rate of 950m³/h specified in the product description for the Prima Klima WHSP EC extractor?
The maximum flow rate of 1400 m³/h indicated for the Prima Klima WHSP EC extractor corresponds to the theoretical capacity in free outlet, meaning without any resistance in the ventilation circuit.
The figure of 950 m³/h mentioned sometimes in the description likely corresponds to a measured flow rate under real conditions, with ducts, bends, or filters that create static pressure and reduce the effective air flow. This difference is typical for any extractor and is not an inconsistency but a physical reality.
In summary, 1400 m³/h is the optimal flow rate announced by the manufacturer, whereas 950 m³/h illustrates a value closer to what you will achieve in use with a complete installation.
Is it compatible with home automation control systems like Zigbee or Z-Wave to adjust flow and speed remotely?
The Prima Klima WHSP EC-Absaugung – Ø150/160 mm fan does not have native compatibility with Zigbee or Z-Wave home automation systems for direct control of flow or speed remotely.
However, its speed can be adjusted via an appropriate external controller, although this is not included. For advanced home automation management, one would need to consider adding a third-party interface compatible with Zigbee or Z-Wave, as the product does not offer this function as standard.
Does the power of 170W allow maintaining an optimal flow rate of 1400m³/h continuously without overheating under intense use in indoor LED cultivation?
The 170 W power of the Prima Klima WHSP EC extractor Ø150/160mm is suitable for maintaining an optimal flow rate of up to 1400 m³/h continuously. This model is designed for intensive use with integrated thermal protection, which stops the motor in case of overheating, thus preserving its longevity.
To ensure optimal operation without overheating under LED lighting, it is essential to provide good ventilation around the extractor and to monitor environmental conditions (temperature, humidity). Using an external controller can help manage these parameters and avoid thermal stress.
In summary, this powerful and energy-efficient EC motor can keep pace indoors, provided there is a well-thought-out installation to facilitate cooling.
What is the difference between maximum flow 1400m3h and operational flow 950m3h real for compact micro-culture?
The maximum flow rate of 1400 m³/h corresponds to the theoretical maximum capacity of the Prima Klima WHSP EC extractor under ideal conditions, without any restrictions. In contrast, the actual operational flow rate of approximately 950 m³/h reflects performance in concrete situations, particularly in compact micro-culture where the limited size of the chamber, the presence of filters, and the moderation of flow to avoid stressing the plants reduce this flow rate.
Using a lower flow rate helps ensure adequate air renewal while limiting noise, energy consumption, and protecting plants from too strong drafts. This adjusted flow rate is therefore optimal for compact micro-culture, ensuring efficiency and cultural comfort.
Is this Prima Klima WHSP EC extractor compatible with an external speed controller to easily adjust the airflow according to the size of my indoor box?

For personalized management, it is possible to control this extractor via an external digital controller, ideal for confined cultivation or integrating ventilation into a home automation system.
Does the Prima Klima WHSP EC extractor remain effective in reducing odors while maintaining a low noise level when the speed is reduced to avoid disturbing the ventilation?
The Prima Klima WHSP EC Ø150/160mm extractor remains quite effective at reducing odors even when the speed is reduced. Its high-quality EC motor allows for precise speed adjustment, ensuring quiet operation without sacrificing the air flow necessary for renewal and odor control.
By lowering the speed, the noise significantly decreases, which limits disturbances in ventilation, while still maintaining sufficient extraction. For very fine flow regulation, an external dimmer can be considered, but overall, this extractor is recognized for its perfect balance between performance, silence, and odor control, making it ideal for indoor crops sensitive to noise.
Is the maximum air flow of 1400 m³/h maintained under real usage conditions or only in the laboratory? Is the sound reduction measurable on-site or mostly marketing? Finally, does the ebm-papst motor come with a real warranty and accessible customer service in case of failure?
Regarding the maximum air flow of 1400 m³/h, this is a theoretical measurement obtained in the laboratory without constraints in the circuit. In real conditions, with filters and bends, the flow is generally around 950 m³/h, which remains excellent for this type of extractor.
The sound reduction is indeed real and perceivable on-site. Thanks to the EC ebm-papst motor and the optimized design, this extractor produces less noise disturbance than classic models, not just a marketing argument.
Finally, the ebm-papst motor comes with a reliable warranty including thermal protection that safeguards against overheating. Customer service is accessible in Europe, ensuring serious support in case of failure, confirming the robustness and professional quality of this equipment.
What is the real difference between the announced air flow rate of 1400 m³/h and the displayed rate of 950 m³/h in the description? Does the efficiency concern only ideal or real growing conditions?
The difference between the announced flow rate of 1400 m³/h and the actual flow rate of 950 m³/h corresponds to the distinction between ideal performance and practical performance. The flow at 1400 m³/h is measured in free air, with no obstacles in the air circuit, reflecting a theoretical maximum capacity.
The flow rate at 950 m³/h, on the other hand, incorporates the actual constraints of your installation (ducting, filters, elbows), which generate static pressure and decrease the effective air flow. This value is therefore more representative of growing conditions.
In summary, actual efficiency always depends on the installation environment, and this phenomenon is classic for all air extractors. The Prima Klima WHSP EC remains efficient and silent thanks to its EC motor, which ensures a good compromise between power and consumption.
