Buyers can place bulk orders for them with us!Details : A vent silencer or a blow off silencer is a device used to reduce unwanted noise created by gas or steam flow in a pipeline discharging directly into the atmosphere. This noise can be generated due to the high velocity flow through the valve and turbulence created around any obstacle in the line that suddenly restricts or changes the direction of flow such as valve or an orifice. Vent silencers find wide applications in high-pressure vents, steam vents, safety relief valve outlets, system blow downs and purge outlets etc. Each vent silencer is designed to attenuate the noise level to the required sound pressure level criteria at a given distance from the silencer. In any steam or gas venting / blow off system, the primary release of noise energy occurs at the open stack exit. The blow off silencer is installed either within the stack or at the stack outlet to intercept this noise before it escapes into the environment. Our vent silencers combine both dissipative and reactive technology in a highly efficient design. Data Required Application (Vent, Blow down, Relief Fluid Composition (Steam, Gas, Air) Molecular Weight or Specific Gravity Process conditions upstream of valve and units (lb/hr, SCFM, ACFM), Temperature Pressure (P 1) Atmospheric pressure ( P a ) and temperature (T 2) if known.

These are noise control solutions designed by our Principal IAC Colpro and manufactured by Indiaflex team of skilled engineers. At Indiaflex we can optimize solutions according to customer requirements. Our extensive experience and technical know-how on a wide range of silencers lends itself to all types of applications including: Discharge to the atmosphere of pressurized fluid (steam, gas etc.) from outlet of starting valves, vent valves or similar. In-line treatment under pressure of compressed gas networks. Treatment of inlets and outlets of large industrial fans. Treatment of inlets and exhaust lines of gas turbines. Treatment of inlets and exhaust lines of engines. Treatment of inlets and outlet suppressors and compressors.

The Drum Safety Valve Vent Silencer offered by is a combination of reactive and absorptive type silencers to attenuate high as well as low frequency noise signals. Clients can avail these as per the specific requirements of their noise reduction application.

Our Vent silencer is specially designed and manufacturing. Heat resistant Aluminium is painted on the surface area. Frequency noise level check is done using software. All the materials that we use are graded materials. We designed the silencer as per the ASME code standards. Exhaust Silencer performance is as per the Noise and OHSAS standards. We have our own testing facility for NDE like RT ,UT, PT, MT. We have qualified welders for all types of welding joints for structural work. Special care is taken in internals like absorbing materials, acoustic packing materials, perforated sheet, rockwools etc, in order to guarantee a long life. Painting on the surface area is check using DFT gauge. Compact and Customized design. Easy Cleaning and Maintenance. Good flow transmission that results in low pressure drop.

Decimin design, manufacture & supplies world-class vent (ventilation) silencers for reducing noise generated by venting of pressurized gases to the atmosphere. The noise levels can be as high as 170 dB(A) and can be reduced to level as low as 75 dB (A) at 1 meter distance with the vent silencer.

Steam and Gas Vent Silencers for venting process gases, HP and LP steam, blast furnace gases and other gases or vapours from pressure.

The aerodynamic noise is produced when venting of high pressurized gas to the atmosphere. The gas vent silencer is mounted on the discharge of the valve. The fluid enters through the silencer inlet (reactive section) where the pressure is reduced as per the requirements and process condition. Then it passes through the annular space between the acoustic packing where the sound energy is absorbed. These are used to attenuate the high as well as low frequency noise to the desired noise level.
