1621401600 Muffler Silencer Breather Unit For Oil Injected Rotary Screw Compressor

Product Introduction

Noise and pulsation at the breather line are not just annoying, they signal an open vent path doing real work. 1621401600 is listed by the OEM parts channel as a muffler/silencer for oil-injected screw compressors, used on vent and breather connections to cut air-borne noise while keeping the passage free. Internally it damps pulsation and traps oil mist carry-over from the relieved air path, so the cabinet stays quieter and the surrounding area stays cleaner.

A collapsed insert or blocked body changes venting behavior and can disturb casing pressure balance, which then shows up as slow recovery, minor oil mist at the breather, or unusual surge noise. Treat it as a serviceable silencer, not a decorative cap—check thread, body length, and flow direction against the removed unit before fitting. Also called muffler, silencer, breather muffler, vent silencer.
