Are Louvers And Dampers The Same Thing

Louvres or dampers are often attached to the back of a heat register.

Are louvers and dampers the same thing.

The louvers do not move hence they have no control over the regulation of air flow and release a standard flow of air while dampers are movable hence they act as a regulator to control the air flow. Dampers are made of metal and usually square circular or rectangular in shape. Heat registers are vent covers that cover the hole in the wall or floor where the duct enters the room. Flowseal multi louvre dampers are designed and fabricated to meet the requirements of power and industrial plants and to comply fully with the requirements of amca publication 850 84.

The main difference between louvers and dampers is that the blades of the louvers are constant and do not move while the blades of the dampers move. Parallel louvers parallel louvers are primarily used for isolation applications. Some industrial dampers are designed for pressure relief or recommended for use within specific hvac systems. Like dampers louvers are usually made of aluminum or steel.

All of the blades rotate in the same direction. Ul rated fire smoke dampers also block out heat and smoke to contain or vent harmful fumes and slow the spread of fire. They provide effective and reliable control and or shutoff in hot noxious corrosive and dirty gas flow conditions. Louvers may be adjustable or suitable for applications that require noise control.

Flowseal louvre dampers can be manufactured with either parallel blade or opposed blade. With the addition of blade seals this damper can achieve better than 99 shut off.
