PERFORMANCE
Exceptional energy efficiency performance puts the VS500 SQ in a class by itself.
With its aluminum counterflow heat exchanger core, the VS500 SQ transfers 81% to 90% of the heat 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.
