Extraction Fans and Kits

Adequate extraction is fundamental to a healthy grow environment — managing temperature, humidity and CO2 while removing heat from your lighting. Your fan should exchange your total grow space volume at least once per minute as a general guide.We currently stock four extraction fan products. The Isomax Acoustic Duct Fan is a high-performance, low-noise centrifugal fan where sound reduction is a priority. The RVK Circular Duct Fan is a reliable, widely used inline fan. The Q-Max AC 250mm 3-Speed delivers up to 1590m³/hr with three speed settings. The Airfan Thermo 315 is a thermostatically controlled 315mm fan that adjusts speed in response to temperature.
