Porvair announces noise reduction device for pneumatic equipment

Offering sound attenuation properties, Vyon porous plastic silencers from Porvair Sciences directly fit into the exhaust port of pneumatic equipment so the noise from air escaping to the atmosphere is reduced to a safe decibel level.

Many industrial organisations use the power of compressed air in pneumatic equipment including blast cleaners, drills, forging pressures and paint sprayers. A notable drawback of pneumatic equipment is their loud operating noise. To reduce the ambient noise from your pneumatic equipment to safe, workable levels it is vital they are fitted with effective silencers.

Vyon is a porous permeable plastic made from high density polyethylene using a proprietary powder sintering process. Using this high-performance material, Porvair Sciences manufactures noise attenuation devices (silencers) to fit almost any pneumatic equipment.

Each Vyon silencer is comprised of a sintered polyethylene body moulded to a high-density polyethylene adapter with British Standard Pipe (BSP) M5 connections or easy-to-use push-in connectors. Once a silencer is fitted, compressed air escapes to the atmosphere by expanding through the porous body of the device.

Vyon silencers can reduce the noise from a single unsilenced exhaust port from about 90 decibels to between 60 and 70 decibels. Noise at 90 decibels level corresponds to the noise produced by a heavy truck or underground train passing at a distance of a few feet. It is widely acknowledged that such decibel levels are dangerous, and people should not be exposed to this level of noise for any length of time. By comparison, 60 decibels correspond to the level of noise from a normal conversation at 3 feet distance and consequently is completely safe.
