the flexible choice
This pair of innovative extractor fans are a great invention that include two separate windings in each unit - enabling them to run at two different speeds depending on your requirements. This is ideal for growers who may need less extraction during winter than they do in summer or for growers who have their grow room near to where they sleep and want to minimise air noise at the flick of a switch. Not as controllable as using a KlimaVator but perfect for gaining control over your extraction at a good price. Also available are plastic spigots that allow you to reduce the outlet diameter on these fans when using the lower speed setting. Wall brackets included.
