Exhaust Fan Silencer Installation

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.

Exhaust fan silencer installation.

Duct clampsthe joint between the inline fan and the adjacent filter or duct silencer. Noise levels can be high and contain low frequency content. Replace windband of fan with silencer. Flexible seals between the silencer and fan can be eliminated by mounting the silencer on support legs and vibration isolation pads so that the.

Blade passing frequency is often the defining noise characteristic when designing an exhaust silencer. Discharge silencers for industrial fans are often required to accommodate very high volumetric flow rates cfm at high temperatures and velocities. 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. Change to an inline fan running parallel to the roof and place a rectangular silencer on the outdoor side.

Fantech ld silencers are typically used for kitchen exhaust systems. Where vertical applications are required aerodynamically enhanced acoustic plenums can be provided. Direct the duct opening away from noise sensitive areas. 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. Installation dos and donts 3 dr ref qxd 6 11 2015 3 58 pm page 18.
