Our portable fan speed control is great for direct control of 120V fans/ventilators. The fan control lets you adjust fan speed for exhaust and circulation fans from 30% to 100% of output capacity – shaded pole , P.S.C. , and universal. It also provides the ability of turning a fan on and off. The controller comes in a weatherproof and corrosion proof, polycarbonate thermoplastic enclosure and comes prewired with 8ft cord. Just plug the item into back of plug and plug into wall outlet.
The fan control is commonly used in the winter when less ventilation is required and too much cold air flow can harm greenhouses.
Has standard 7/8 opening and we recommend using our strain relief cord connector that can be purchased here.
