PERFORMANCE

Exceptional energy efficiency performance puts the VS500 SQe in a class by itself.

With its polymer counterflow heat exchanger core, the VS500 SQe transfers 71-86% of the heat and 51-79% of the moisture between fresh and exhaust air streams.

Our fans incorporate electronically commutated motors (ECMs) and backward curving fan blades, reducing the power required for air movement.
