We all know the importance of good air exchange for indoor grow rooms to supply your plants with CO2 rich fresh air, to extract old, stale air and to also help with odour control. Good intake and extraction can also help manage room temperature and humidity levels, which is also a vital to getting optimum performance from your hydroponic equipment and also your plants.

The RVK in-line duct fans by SystemAir are one of hydroponics most recognisable names for manufacturing powerful, efficient and with low noise, grow room intake and extraction fans. They’re available in various sizes from 4” (100mm) through to 12.5” (315mm) and with two different power outputs, A1 (lower) and the L1 (higher).
