Here is the PK125-WHSP 2 exhaust fan from Primaklima. This extractor provides an airflow of 340 m³/h and 460 m³/h, thanks to its 63W centrifugal motor. The WHSP (Whisperblower) range is an extractor line with a built-in silencer. Its design makes it 2.5 times quieter than standard models. Both intake and exhaust ports have a 125 mm diameter.
The PK125-WHSP 2 extractor will allow you to optimally control your grow tent.
Equipped with a ball-bearing-mounted turbine, it operates with minimal noise levels (2.5 times quieter than other models in its category).

How to Use the PK125 WHSP-2 Air Extractor
To get the most from your extractor and ensure an optimal indoor grow:
-
Placement
Install the extractor near the top of your grow space, close to an air outlet. Hot air naturally rises, so locating the extractor up high helps remove heat more efficiently.
-
Duct Connection
Use an appropriately sized ventilation duct (Ø125 mm). Make sure to secure the ducting with clamps to prevent any air leaks.
-
Speed Adjustment
Select the appropriate speed based on the climate conditions inside your grow area.
- Speed 1 (360 m³/h): Ideal for small to medium grows or during cooler periods.
- Speed 2 (460 m³/h): Perfect for managing significant heat buildup, especially under intense lighting or during flowering when plants are more sensitive to heat and humidity.
-
Climate Control
Consider using a climate controller (thermo-hygrometer) to monitor temperature and humidity. Adjust the extractor’s speed as needed according to your plants’ real-time requirements.
-
Maintenance
Regularly remove any dust or residue from the extractor’s turbine and ducting to maintain optimal performance and extend the device’s lifespan.
Associated Products for a High-Performance Indoor Grow
Pair your 2-speed PK125 WHSP-2 Air Extractor with accessories and equipment for best results:
-
Activated Carbon Filter

-
Thermostat or Speed Controller
Automatically adjusts the airflow based on temperature. This helps optimize energy use and prolong the extractor’s lifespan.
-
Soundproof Ducting
Further reduces noise. A must-have if you need maximum discretion.
-
Circulation Fan
Complements the air extractor by circulating air inside the grow space, distributing heat and humidity evenly, and strengthening plant stems.

Grow Tent (Box)
Choose a tent suited to your available space and equipped with a 125 mm exhaust port. This guarantees a controlled environment and simplifies ventilation setup.
(FAQ)
-
Should I run the air extractor continuously?
It’s generally recommended to keep the extractor running during lighting periods, if not 24/7, to maintain fresh air and avoid sudden humidity spikes. However, using a thermostat or timer can help you customize operating times to your specific needs.
-
How do I know whether to use speed 1 or speed 2?
Choose your speed based on the temperature and humidity in your grow space. If heat or humidity levels get too high, switch to the higher speed (460 m³/h). If the conditions remain stable (around 24–28 °C), the lower speed (360 m³/h) may be sufficient.
-
What is the lifespan of this extractor?
The PK125 WHSP-2 from Prima Klima is built with quality materials and a robust motor, typically lasting over five years under heavy use. Regular cleaning (of the turbine and ducts) will help extend its service life.
-
What maintenance does this extractor require?
Periodically clean the turbine and check your ducting to remove dust and debris. A dry or slightly damp cloth should suffice. Also remember to replace your carbon filter (if used) every 6 to 12 months, depending on usage intensity.
-
Can I use this extractor in a hydroponic system?
Absolutely! The PK125 WHSP-2 extractor is suitable for all indoor grows—soil, hydroponics, aeroponics, or coco. Its main function remains the same: to renew the air, manage temperature, and control humidity for a stable, healthy environment.
