IFD Inline Foam Damper

The IFD Inline Foam Damper is an inline damper for circular ducts. It is completely made from soft elastic plastic foam with good damping abilities. The damper has a number of oval openings equipped with releasable plugs. The pressure drop across the damper is adjusted by varying the number of open holes.

Due to the special material and the design of the holes, sound generation will be low even at large pressure drops. The damper is equipped with a measurement outlet to make adjustment faster. The stable plastic foam has an open cellural structure and high density, which makes for an extraordinary ability to absorb sound. Because of this, the damper acts as a simple silencer.

By placing several dampers after one another in a duct, the silencing is increased further. Sound problems, such as overhearing between rooms, can often be solved.
