Bypass Damper

The exodraft Bypass Damper is used in exhaust systems to control the hot flue gases/process air to the Basic Plate heat recovery devices. A Bypass Damper is used primarily for larger boiler systems, industrial processing plants, or commercial systems.

All parts in contact with flue gas are made from stainless steel EN 1.4404. All exterior parts are made from stainless steel EN 1.4301. An integrated electric motor opens and closes the damper. Power supply and start/stop signal come from an external exodraft panel, and is not a part of the Bypass Damper. The Bypass Damper has a safety spring return, causing it to close automatically in case of a power failure.
