How it works

The FIT® 120E brings a continuous supply of fresh air into a home while exhausting an equal amount of contaminated air. The energy recovery core at the center of the unit transfers heat and moisture from the incoming air to the outgoing air that was cooled and dried by the building's air conditioner.

Dimensional information in inches (mm)


Two (2) factory-balanced fans with backward curved blades. Motors come with permanently lubricated, sealed ball-bearings to guarantee long life and maintenance-free operation.

Energy Recovery Core 

AHRI certified core made from water vapor transport durable polymer membrane that is highly permeable to humidity. The ERV core is freeze tolerant and water washable. Core dimensions are 11.5” x 11.5” (290 x 290 mm) with a 7.8” (198 mm) depth.

Frost Prevention 

A preset frost prevention sequence is activated at an outdoor air temperature of 14°F (-10°C) and lower. During the frost prevention sequence, the supply blower shuts down and the exhaust blower switches into high speed to maximize the effectiveness of the frost prevention strategy. The unit then returns to normal operation, and continues cycle.


Core, filters, fans and electrical panel can be accessed easily from the access panel. Core conveniently slides out with only 8” (203 mm) clearance.


24 gauge G90 galvanized steel.


Insulated with 1 in. (25 mm) of foil-faced high density polystyrene foam an 0.25 in. (6 mm) of closed-cell foam on the top of the unit.


Two (2) washable electrostatic panel type air filters. Exhaust air filter dimensions 11.2” (284mm) x 7” (176 mm) x 0.125” (3mm). Supply air filter dimensions 11.4” (289mm) x 7.7” (196 mm) x 0.125” (3mm).


Unit is typically hung by using ceiling bracket supplied with unit. Optional chain kit available.
