Exhaust Fan Silencer Installation

Where vertical applications are required aerodynamically enhanced acoustic plenums can be provided.

Exhaust fan silencer installation. 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. When attached to an inline or remote fan the ld silencer dramatically reduces the sound traveling through the duct. Direct the duct opening away from noise sensitive areas. Discharge silencers for industrial fans are often required to accommodate very high volumetric flow rates cfm at high temperatures and velocities.

Duct clampsthe joint between the inline fan and the adjacent filter or duct silencer. The vibration of the fan amplifies even more at this kind of joints to overcome the issue use a clamp as a joint media in between the fan and filter silencers. An excellent way to reduce the amount of noise is to use a fan speed controller. Noise levels can be high and contain low frequency content.

Replace windband of fan with silencer. Fantech ld silencers are typically used for kitchen exhaust systems. Blade passing frequency is often the defining noise characteristic when designing an exhaust silencer. Change to an inline fan running parallel to the roof and place a rectangular silencer on the outdoor side.
