It is light weight, durable and highly effective for noise reduction without excessive back pressure. The uniquely structured porous polyethylene element channels the escaping air through a tortuous path, to reduce the noise level within OSHA requirements. 

The durable porous polyethylene body can withstand high working pressures up to 150 PSI. In an unlikely event of a blowout, resilient porous plastic body will not shatter, therefore no danger of flying fragments. 

The polyethylene plastic is completely non-corrosive and highly resistant to water and oil usually present in compressed air lines and can be easily cleaned with methylene chloride or similar cleansing fluid.
