Industrial Dampers

Listing ID #3189593

A duct damper is a device used within a heating, ventilation and air conditioning (HVAC) duct. These ducts carry air from furnace or air conditioning units to the different rooms within the building. A duct damper can help control the flow of this air, or can even prevent the air from entering specified areas. By regulating air flow, the duct damper can be used to control temperature and humidity levels, restrict the flow of dangerous fumes or smoke, or simply give homeowners more control over comfort levels and drafts. These dampers can take a number of different forms depending on the desired function. A duct damper may contain a rotating flapper-type mechanism, which will pivot back and forth within the duct to control air flow. It may also contain a louver or vent-type mechanism, which can slow or redirect air flow, but is ineffective at blocking airflow completely. Finally, guillotine dampers are designed to block the entire duct so that air is unable to enter a specific area. There are two basic types of duct damper models. Volume air dampers control overall air flow as part of the building̢۪s heating and cooling system. As the thermostat is adjusted, the dampers automatically activate to increase or decrease air flow. They can also be used to redirect conditioned air out of closed-off rooms, which prevents wasted energy.-Volume control Damper, Fire & Smoke Dampers .
