  • Hardwired (hard-connect) for direct connection to the home electrical mains  (-HC version)


FIT fits multi-family projects

Designed for multi-family residential applications, the FIT® appliance brings a continuous supply of fresh air into the premises while exhausting an equal amount of contaminated air out.

10" Installed Depth

Simplifies installations with limited mechanical space, such as over a false ceiling.

Energy Efficiency

The energy recovery core transfers both heat & moisture from the outgoing exhaust air to the incoming fresh air, reducing the energy required to condition it.

Frost Prevention

Equipped with a preset frost prevention sequence, the appliances automatically activate when outdoor temperatures drop to 14°F (-10°C) or lower.

In the Box

This appliance comes with two washable, UL900-certified, electrostatic panel-type air filters, integrated in-door manometer ports, an external electrical box with easy-connect ports, a ceiling mounting bracket, and metal collars with rubber gaskets to ensure a tight connection on rigid ductwork.
