EC Fan Technology

EC Fan Technology

The Electronically Commutated (EC) backward curved plenum fan is the key to this product’s efficiency. The Mini-Space is able to provide a fully scalable air volume with EC fans that are designed to operate at reduced speed. The result is significant energy savings and lower maintenance costs compared to belt driven forward curved fans.
