Prima Klima WHSP EC-TC Silent Extractor Fan - Ø125mm - 800 m³/h

With a maximum airflow of 800 m³/h it suits large tents (1.2 × 1.2 m and beyond) or multi-light spaces. The rule of thumb is to replace the grow's air volume at least every 1 to 3 minutes; this airflow gives a wide margin, especially as the temperature probe modulates power to your real needs.

The EC-TC thermo-controller ships with a probe you place inside the tent. You set a minimum and a maximum speed, and the electronics then automatically vary the motor's speed based on the measured temperature — speeding up in the heat and slowing down as the air cools.

Yes, that is the whole point of the WhisperBlower (WHSP) range. The insulated body and EC motor cut noise substantially compared with a standard fan of the same airflow. For an even more discreet result, pair it with acoustic ducting and anti-vibration mounts.

To neutralise odours, yes: choose an active carbon filter in Ø 125 mm, sized for at least 800 m³/h. Because the extractor is optimised for this use, it keeps airflow effective even with the filter and ducting connected.

The EC-TC motor uses less power, runs cooler and, above all, can be finely controlled via the temperature probe, whereas an AC motor often runs at a fixed speed or in steps. You gain control precision, quietness and energy savings over time. In practice this means fewer temperature swings, a healthier canopy climate and less manual tinkering throughout the grow.
