This fan offers high performance at low wattage and can deliver a maximum airflow of 1008 m3/h. It can be easily connected to other ventilation devices, such as silencers to reduce noise levels or a carbon filter if you use it in your grow room. The RVK 200 L1 is an inline fan that can be installed directly into the ventilation system. Its speed can be controlled with a triac or via the voltage. Both experienced and new growers have used Systemair's RVK fans for years because of their performance, quietness and low cost - plus they're virtually indestructible.
