A fan radiates noise through both its inlet and its discharge. In most cases, either the fan inlet or discharge is connected to some type of equipment which absorbs the noise from that side of the fan. Normally, only the inlet or discharge needs to be silenced.

The Aeroacoustic Corporation has designed a series of six fan silencers, made up of a wide variety of sizes and capacities, that are compatible with popular fan sizes and types to reduce the noise levels to those required either by law or customer preference. We also offer a wide variety of accessories, including but not limited to flow tubes, rainhoods and filter assemblies.

Inlet Silencers

"Silentflow" MODEL CI

"Silentflow" MODEL CI (For single-inlet fans without inlet boxes - horizontal inlet)

"Silentflow" Model CI inlet silencer is designed to bolt directly to the fan inlet flange. The silencer includes a silencing section followed by a plenum section with one or two access doors for installation and inspection. A 1" x 1" galvanized mesh inlet screen is included at no additional cost.

"Silentflow" MODEL SI

"Silentflow" MODEL SI (For single-inlet fans without inlet boxes – 90 deg. Inlet)

The "Silentflow" Model SI inlet silencer is designed to bolt directly to the fan inlet flange. The silencer includes a silencing section followed by a plenum section large enough to accommodate the fan inlet opening. One or two access doors are incorporated into the back of the plenum for installation and inspection. A 1" x 1" galvanized mesh inlet screen is included at no additional cost.

"Silentflow" TUBULAR

"Silentflow" MODEL TI TUBULAR (For a very low pressure drop)

The "Silentflow" Tubular silencer is used where noise reduction is needed combined with a very low pressure drop. It is designed to bolt directly to the fan inlet, but can be combined with a round-to-round transition to allow the fan inlet to attach to larger tubular silencers . Where necessary, certain models of the Tubular silencer are outfitted with centerbodies to further improve performance of sound attenuation.

"Silentflow" MODEL IB

"Silentflow" MODEL IB (For fans with inlet boxes)

The "Silentflow" Model IB inlet silencer features an internal configuration designed so that the silencer exit matches the fan inlet box. The silencer's discharge flange is customized to fit the fan's inlet box bolt pattern, eliminating the need for a separate transition piece. A 1" x 1" galvanized mesh inlet screen is included at no additional cost. (Please call for assistance)

Discharge Silencers

"Silentflow" MODEL CI

"Silentflow" MODEL DF (For discharging to the atmosphere)

The "Silentflow" Model DF discharge silencer is designed to be used when the fan inlet is connected to the process but discharges to atmosphere. The required silencer is generally larger than the fan discharge connection, in which case a transition may be purchased to connect the silencer to the fan.

"Silentflow" TUBULAR

"Silentflow" MODEL TO TUBULAR (For a very low pressure drop)

The "Silentflow" Tubular silencer is used where noise reduction is needed combined with a very low pressure drop. It is designed to bolt directly to the fan discharge, but can be combined with a round-to-round transition to allow the fan discharge to attach to larger tubular silencers . Where necessary, certain models of the Tubular silencer are outfitted with centerbodies to further improve performance of sound attenuation.
