Product Description
Panasonic BalancedHome™ Elite Plus+ FV-21VEC1S is a 210 CFM Energy Recovery Ventilator (ERV) with horizontal duct orientation, providing tempered supply air while exhausting stale indoor air. Independent supply and exhaust settings give balanced ventilation while recovering energy from the exchanged air, with adjustable 40–210 CFM and an occupant-controlled boost up to 210 CFM. The unit features two DC-enclosed ECM brushless motors, MERV 13 (FV-FL1321VE1) filter, ASHRAE 62.2 timing function, and built-in frost prevention. Engineered for use in any temperate North American climate zone. Specs verified from the Panasonic specification sheet.
