Fan Silencers Dealers

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.

The fan silencer is used to reduce the suction and discharge noise of the fan. It is an absorptive type silencer and is very effective for high frequency noise attenuation. Consequently fan silencers shall be supplied in rectangular shape.The internal of fan silencer is constructed with series of rectangular baffle with aerodynamic design to offer minimum pressure drop. The following data are required to design fan silencer. Application Flow rate Temperature Fan inlet / outlet size (Depending on application) Allowable pressure drop Silenced noise level requirements

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.

Leveraging on our extensive market knowledge, we are providing a high quality range of Industrial Fan Silencer. However, in any mechanical device that requires components to rotate at high speeds, noise can become problematic.

Industrial Fan Silencers are installed depending on fan size, horse power, air flow, type and number of blades, static pressure, rotational speed etc. We are named among the renowned Manufacturers, Exporters and Suppliers of Industrial Fan Silencers. The manufacturing of these silencers is done using the latest techniques under the strict vigilance of experts. One can place retail as well as bulk orders for Industrial Fan Silencers with us. Details :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 noise control is achieved by means of absorption. The acoustic energy propagating through the silencer is effectively absorbed into the fibrous absorption material and converted into heat energy. These silencers generally employ straight thru design and have a low pressure drop as it imposes very little restriction to the flow. The 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 fan silencer, it must be ensured that the flow area throughout the silencer is sufficient to accommodate the air flow without imposing excessive restriction. Data Required Air Flow Rate (Actual CMH) Temperature (°F) Pressure (PSIG) Maximum allowable pressure drop (inches of water) Existing noise frequency spectrum (63).

We are offering fan intake silencer, our company is offering a wide range of fan intake silencer. Our fan intake silencer is used to reduce the suction and discharge noise of the fan used in cooling of the infrastructure and different machines. It is an absorptive type silencer and is very effective for high frequency noise attenuation.

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. Multiple duct baffles with acoustic material of resin bonded fibre glass mineral wool supported inside perforated sheets at fan inlet. Alternatively circular central core intake Silencer with centre core , baffle supports and housing, lined with mineral wool inside the perforated sheet. Outlet Silencer- baffle type or Centre core type Sound insulation with mineral wool inside perforated sheets in the scroll portion of the casing , inlet duct , suction Chamber and outlet duct Coating of all the fan parts in flow area with sound insulation material. For improved noise insulation a fan enclosure with silencer lining and weather protection

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. Lifting lugs and saddle are provided with proper calculating load and stress. Heat Resistant Aluminum Paint is applied on the surface area (800°C) based on customer requirement. Quality acoustic fills and Insulation is used. Sandblasting is done on the surface area. We have qualified welders for all types of welding joints for structural work. We have approval from third party inspection for WPS, PQR and WPQ records for all the welding positions like 1G, 2G, 3G, 4G, 6G. We have NDE LEVEL-II inspector for RT, UT, VT, PT, MT
