Application
Fantech's most popular HRV for home projects, the VHR 150 is designed for higher static pressure applications.
How it works
The unit brings a continuous supply of fresh air into a home while exhausting an equal amount of contaminated air. During winter, fresh incoming air is tempered by the heat that is transferred from the outgoing air so you save on energy costs, while during summer, the incoming air is pre-cooled if the house is equipped with an air cooling system. The VHR 150 is equipped with automatic defrost mechanisms so you can use your HRV all year long.
Defrost cycle
A preset defrost sequence is activated at an outdoor air temperature of 23°F and lower. During the defrost sequence, the supply blower shuts down & the exhaust blower switches to high speed to maximize the effectiveness of the defrost strategy. The unit then returns to normal operation, and continues the cycle.

Fans
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.
Heat Recovery Core
Aluminum heat recovery core covered by a limited lifetime warranty. Core dimensions are 9” x 9” (229 x 229 mm) with a 15” (380 mm) depth. Our heat exchangers are designed and manufactured to withstand extreme temperature variations.
Frost Control
A preset frost control sequence is activated at an outdoor air temperature of 23°F (-5°C) and lower. During the defrost sequence, the supply blower shuts down & the exhaust blower switches into high speed to maximize the effectiveness of the defrost strategy. The unit then returns to normal operation, and continues cycle.
Serviceability
Core, filters, fans and drain pan can be easily accessed through latched door. Core conveniently slides out on our new easy glide core guides. 17" (432 mm) of clearance is recommended for removal of core.
Duct Connections
