Controlled environments, now with even more control.

Electronically Commutated Motor (EC)

The SPX-EC is Technical Air Product's most feature rich FFU, offering customers the highest level of performance and control. The electronically commutated motor is a variable speed motor which automatically ramps up or down to keep a consistent air flow. When teamed with an auto-control card, the SPX-EC fan filter unit can provide customers with a completely automated clean air environment.
