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.
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
Volume = Length (m) × Width (m) × Usable Height (m)
- 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
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.

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
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).
