An axial fan silencer is available to fit any fan size with construction materials suitable towards a system type a fan size and a higher velocity of a fan type.
Exhaust fan silencer installation.
Two silencers can be used together in installations where noise reduction is critical.
Noise levels can be high and contain low frequency content.
Replace windband of fan with silencer.
An excellent way to reduce the amount of noise is to use a fan speed controller.
The available types of axial fan silencers include media filled with film liner dissipative media filled and no media designs.
Exhaust silencers have mounting flanges to suit standard fan bolt patterns for easy installation.
Duct clampsthe joint between the inline fan and the adjacent filter or duct silencer.
Change to an inline fan running parallel to the roof and place a rectangular silencer on the outdoor side.

Direct the duct opening away from noise sensitive areas.
When attached to an inline or remote fan the ld silencer dramatically reduces the sound traveling through the duct.
Fantech ld silencers are typically used for kitchen exhaust systems.
Where vertical applications are required aerodynamically enhanced acoustic plenums can be provided.
Blade passing frequency is often the defining noise characteristic when designing an exhaust silencer.
