Are Louvers And Dampers The Same Thing

With the addition of blade seals this damper can achieve better than 99 shut off.

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. Parallel blade louvers are also used on inlet boxes of large industrial fans to promote pre spin to the in rushing air thus. 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. 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.

Dampers are made of metal and usually square circular or rectangular in shape. All of the blades rotate in the same direction. Louvers may be adjustable or suitable for applications that require noise control. Louvres or dampers are often attached to the back of a heat register.

Heat registers are vent covers that cover the hole in the wall or floor where the duct enters the room. These adjustable louvers dampers can open or close the register to open and close the flow of air. Ul rated fire smoke dampers also block out heat and smoke to contain or vent harmful fumes and slow the spread of fire. Our dampers meet air leakage requirements set by ashrae amca and the international energy code council iecc which encourages energy conservation efficiency in building envelope design and may also assist in obtaining.

Some industrial dampers are designed for pressure relief or recommended for use within specific hvac systems. They provide effective and reliable control and or shutoff in hot noxious corrosive and dirty gas flow conditions.
