Product Description

BACK DRAUGHT DAMPER / ONE WAY SHUTTER

Volume control dampers are specially designed for use in heating, ventilating and air conditioning systems for volume, and flow and pressure control of air within the ducts.

 

1. Easy to install.
2. They run efficiently and quietly, leaving homeowners to forget that they're even part of the process.
3. Regardless of the size of your duct network, VENTECH has backdraft dampers to fit a variety of different size ducts.

The backdraft damper is unique in that when air flows out of it gravity is the only source by which the backdraft damper closes and prevents contaminated air to filter back through.
 

A backdraft damper is used on heat exchangers, exhaust systems, solar heating systems; and can be installed in either a horizontal or vertical position with minimal leakage.
