Overview
The Arrow Pneumatics ASP-8 muffler filter is a compact 1″ NPT exhaust silencer that combines noise reduction with particulate filtration for compressed air systems. Built with a sintered bronze element rated at 40 microns, this unit effectively muffles exhaust noise while filtering gasoline, oil, and airborne contaminants. Arrow’s controlled-porosity sintered bronze technology diffuses escaping air to meet OSHA noise requirements while protecting downstream equipment and improving operator comfort.
