A fan radiates noise equally through its inlet and its discharge. Usually either the inlet or outlet of the fan is connected to some sort of equipment which contains and/or absorbs the noise from that side of the fan. Normally only the inlet or discharge has to be silenced. One exception is that type of air conditioning systems in which both the inlet and the discharge are ducted into occupied spaces. In these installations silencers are often required on both the inlet and discharge sides of the fan.

Be it a rural or urban setting, noisy equipment is an issue. You may need to meet a noise ordinance, regulation or just want to be a good neighbor. The use of an acoustical barrier is an effective solution to reduce the noise level at the receiver without interfering with equipment operation. Here at The Aeroacoustic Corporation we have an engineered solution to meet your requirements.

The above shown acoustic louver doors swing in so that they do not obstruct corridor traffic. They help allow the engine room to breath freely and significantly reduce excessive sound energy into personnel corridor. This series of acoustic louver doors are completely at home in a wet wash down environment.

Model IB Inlet Box Silencers

Model DF Discharge Silencers

Model CI Circular Inlet Silencers

Model SI Side Inlet Silencers

Tubular Silencers

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.

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" 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.

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.

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, but can be combined with a round-to-round transition to allow the fan 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.
