RVK Systemair Extractor Fan — German-Engineered Reliability
The RVK Systemair fan has been the reliable workhorse of UK grow rooms for years — German-made, robust, cheap to run, and simply keeps going. Available in two versions: A1 (standard) and L1 (more powerful). Designed for 24-hour continuous operation, properly insulated to handle humid grow-room conditions, and a strong low-cost alternative to pricier acoustic fans.
Why growers choose RVK fans:
German-engineered build quality — proper Systemair components, not a budget knockoff
Robust and reliable — the fan you install and forget about for years
Two versions: A1 (standard) and L1 (more powerful) — match power to tent size and filter load
Rated for 24-hour operation — designed for continuous running, unlike domestic-grade alternatives
Low running costs — efficient motor design, cheap to keep running
Insulated for grow-room conditions — handles humidity and temperature variation without failure
Proven track record in UK grow rooms — been around long enough to know it works
Who it's not for:
Open-housing design — you will hear it running. For quiet operation, step up to an acoustic box fan (Tornado, Gekko) or pair with an inline silencer. A1 and L1 have different airflow ratings — check you're ordering the right one for your tent size. Check the diameter matches your filter and ducting.
