G.A.S Step Controller Pro



The GAS Step Controllers are the best AC fan controllers available. Quiet, simple to use, and the most efficient way to regulate your AC fans, with no clicking between steps like other controllers. Unlike other controllers which may cause humming and excess motor noise when your fans are dimmed below a certain level, the Step Controller uses mechanical step control which ensures they remain totally silent. 

The digital controller technology with solid state relays create a top quality 5 step transformer. Made in Europe to the highest standards, with the grower in mind. The silent seamless changes between steps removes the loud clicking that some controllers have.
