We are offering fan silencers industrial fan installations, small or large, produce noise. This fan noise is one of the most predominant noise sources in an industrial plant. The magnitude and intensity of noise will vary depending on fan size, horse power, air flow, type and number of blades, static pressure, rotational speed, etc. Fans normally deliver a large volume of air at relatively low static pressures usually measured in inches of water. The rotating action of vanes produce a broad band noise spectrum however, the noise in mid to high frequency range is heard to be louder and requires to be treated for achieving noise control. Generally, silencers are used at intake and discharge of fan installations for treating air borne noise. Fan silencers usually require absorptive type design as they are well known for better attenuation in mid and high frequency range (500-8000 hz). The effectiveness of absorption material progressively reduces at frequencies above and below this range.

The centrifugal fan silencers are normally selected on the basis of maximum allowable pressure drop at rated flow and the silencing criteria. These silencers are usually sized for around 5000 to 5500 FPM velocity but not exceeding 7500 FPM velocity to prevent excessive self generated noise and aerodynamic noise generation. While selecting the centrifugal fan silencer, it must be ensured that the flow area throughout the silencer is sufficient to accommodate the air flow without imposing excessive restriction. Centrifugal Fan Silencers must be carefully matched to the fan inlet or outlet air profile to provide the most economical fan noise control with the lowest additional static pressure requirements. Galvanized, stainless steel and painted constructions are all available. Dissipative media filled, media filled with film liner, and No-Media designs are selected to suit the application. Numerous accessories are available for filtering, rain hoods, flow measurement, bird screens, and flange connection types. Baffles Cooling Systems works hard to make sure these concerns are alleviated with proper design regarding Centrifugal fan silencers.     Fan Noise Varies with Static Pressure Fan Efficiency Air Flow Fan Speed Major source of centrifugal fan noise are Air Inlet and Outlet of primary fans Inlet of FD fans and the outlet of ID fans Fan casing Motor       Centrifugal Fan Silencer Features: Heavy gauge perforated sheet is used.

Primary air fans, forced draft fans, and induced draft fans generally require some form of acoustical treatment. Most applications require inlet andor outlet silencers to meet Noise Standards and other noise requirements. For continuous exposure, a maximum of 90 dBA is generally specified to avoid hearing damage. When conversation near the fan is desired, levels of 80 dBA and less are often needed. We designs and manufactures a complete line of silencers for application on all fan types. Computer-enhanced technology developed for fan, turbine, and other air-moving equipment enables Us do offer a cost-effective solution to every fan silencing application. We offers four designs, each with unique advantages, depending upon application-specific requirements for octave band attenuation, pressure drop, and space utilization.

Both suction and discharge silencers shall be supplied either in circular or rectangular construction for fan blower and turbo blowers. The rectangular silencer shall be of absorptive type installed either at suction side or at discharge side of fan blower. The internals of the silencer comprises a series of acoustic splitter elements arranged in parallel inside the rectangular steel casing. This would ensure the flow of airgases through the rectangular air gap between acoustics splitters and thus offering a minimum pressure drop. The leading and trailing edge of the acoustic splitters will be designed aerodynamically to offer minimum resistance to the flow medium.

In order to have the basic data input for design-noise level measurements are carried out under normal load conditions, full load conditions and also with damper closed conditions. The measurements are carried out at number of locations at fan inlet and at distances of 1 or 2 or 3 metres. The noise contour at number of octave frequency bands are plotted and the Silencer is designed on the following considerations. - The source noise level at fan inlet under full load conditions shall be brought down nearer to NC80 Curve by suitable combination of acoustic systems. - The pressure loss across the silencer shall be around 25 mm wcl. The selected combination of acoustic systems may consist of any one or a combination of two or three components.
