Do you compromise?

  • Improper fan backdraft solution puts your air filtration investment at risk.

  • All available fan backdraft solutions involve high building construction costs and/or compromising airtightness.

  • Fan louvers and air chutes significantly reduce the performance of ventilation systems and accelerate wear of fan motors.

Make no compromise with the best fan backdraft control system

No BackDraft is the most efficient fan backdraft control system for any air-filtered barn. It features a simple, robust, and ingenious automatic close/open mechanism that allows complete airtightness without compromising fan efficiency.

Its patented mechanism keeps the damper open at the required angle to maximize air flow when the fan is running and closes it tight with sustained pressure against a rubber seal when the fan turns off. No Backdraft requires no electricity and works in perfect unison with fan action.

Advantages and benefits

Easy

Quick and easy installation on any existing fan design or size (up to 55'').

Efficient

CFM/Watt ratio improvement allows for increased fan energy efficiency.

Full protection

Allows to remove original fan louvers to increase fan efficiency, without reducing protection against contaminated air infiltration.

Insulated

Insulated damper eliminates the need for insulated winter fan cover.
