The Prima Klima WHSP2 extractor Ø125mm with 2 speeds (360/460 m³/h) does not have a built-in system for automatic speed control based on temperature or humidity. The settings are made manually between the two available speeds.
For automatic control, an external system will need to be considered or opting for a model equipped with a speed controller compatible with sensors, like some extractors with graduated speed control.
The Prima Klima WHSP2 Ø125mm extractor at low speed (360 m³/h) is designed for continuous operation without overheating, perfectly suited for a 4 m² growing space with multiple varieties.
In terms of electric consumption, it consumes about 50 to 55 W at this speed, which is approximately 1.2 to 1.4 kWh per day for continuous use (24h). This represents a reasonable energy impact to ensure good ventilation and maintain an optimal growing climate.
For sustainable efficiency, make sure to regularly check the state of the charcoal filter and the cleanliness of the extractor.
The Prima Klima WHSP2 Ø125mm stands out with its Whisperblower technology, ensuring noise reduction up to 2.5 times more effective than traditional extractors, while maintaining excellent airflow (360/460m³/h).
It is thus perfectly suited for environments where silence is crucial, such as bedrooms or offices, especially if the extractor is installed with good sound insulation. Several users emphasize that it remains quite silent even at maximum speed, making the device ideal for use where acoustic comfort is important.
This model combines performance and discretion, making it an excellent choice for indoor installations where noise levels must be minimal.
To optimize the management of temperature and humidity with the Prima Klima WHSP2 extractor (Ø125mm, 2 speeds), it is recommended to adjust the speed according to the growth phase:
During the growth phase, prefer the low speed (360 m³/h). It ensures sufficient air renewal while maintaining a stable environment, with less thermal and noise stress.
During the flowering phase, switch to the high speed (460 m³/h) to better expel the increased heat and humidity, thus limiting the risks of mold and assisting the active metabolism of the plants.
It is essential to regularly monitor the temperature and humidity in your growing space, and manually adjust the speed accordingly. For more convenience, you can also pair this extractor with an external thermostat that will automate these changes.
To precisely adjust the speed of the Prima Klima WHSP2 extractor and optimize ventilation without disturbing ambient silence, use its two available speeds: 360 m³/h for quieter growth phases and 460 m³/h for increased air renewal needs.
Ensure that the airflow remains constant, unobstructed, especially at the carbon filter if you are using one. Install the extractor in an open space to fully benefit from its silent design. Regular maintenance, particularly checking the ball bearings, ensures optimal and discreet operation.
Finally, to adjust precisely according to temperature, pair it with an external control system: this allows ventilation to adapt to climatic variations without excess noise.
For a cultivation area of 1.20 m x 1.20 m (approximately 1.44 m²), the Prima Klima WHSP2 Ø125 mm with its two speeds (360/460 m³/h) is perfectly suited. It is recommended to use the low speed at 360 m³/h, which ensures a sufficiently high air renewal for a volume of about 2.6 m³ (standard height 1.8 m), while limiting electrical consumption and noise.
This low speed guarantees efficient continuous operation due to its silent AC motor and optimized design, ideal for maintaining stable temperature and humidity. The high speed can be used occasionally during heat or humidity spikes, but is not necessary for daily operation for this surface.
Just make sure that the carbon filter or any other filtration system is not obstructed, in order to avoid unnecessarily increasing the load and noise of the extractor.
The Prima Klima WHSP2 Ø125mm at high speed (460 m³/h) is about 2.5 times quieter than a standard extractor of the same diameter thanks to its Whisperblower technology and its noise-insulating nylon polyamide casing, which reduces noise by approximately 4 dB more while providing superior airflow and air pressure.
To optimize its use in a compact box and limit heat:
This advanced design makes the Prima Klima WHSP2 particularly suitable for confined spaces where silence and thermal efficiency are essential.
The Prima Klima WHSP2 Ø125mm extractor has a two fixed speed system: 360 m³/h on low speed and 460 m³/h on high speed. This simple yet effective management allows the ventilation to be adapted to the specific needs of the cultivation phases.
During the growth phase, it is advisable to operate at low speed to ensure sufficient air exchange while limiting thermal and noise stress. In the flowering phase, switching to high speed improves heat and humidity evacuation, thus preventing mold risks and promoting an optimal environment.
The switching between these two speeds can be done manually or via an external thermostat for automation according to the measured parameters in the cultivation. This solution offers precise regulation tailored to the plants' needs while remaining quiet and energy-efficient.
The ebm-papst AC motor of the Prima Klima WHSP2 extraction system is designed with two fixed speeds accessible via an integrated selector. This motor is not compatible with a standard speed controller, as its regulation is done by changing windings and not by continuous electrical modulation.
To adjust the speed accurately and continuously, an EC motor designed to be controlled by a controller would be required. Thus, the WHSP2 model imposes a choice between its two offered speeds, with no option for fine variation with an external controller.
The Prima Klima WHSP2 Ø125mm extractor with its two speeds (360 and 460 m³/h) provides precise and tailored management of the microclimate in SCROG under compact LED.
At low speed (360 m³/h), it ensures sufficient air renewal to stabilize temperature and humidity while being energy-efficient and very quiet, ideal for continuous operation. High speed (460 m³/h) comes into play during thermal peaks or humidity for more intense mixing, thus avoiding plant stress and pockets of hot or humid air.
This dual adjustment allows for precise ventilation according to the phases of growth, guaranteeing an optimal environment under compact LED that generates less heat but requires a constant and controlled airflow. Moreover, its silent operation enhances comfort in a confined space.
