- This porous metal muffler includes a manually-adjustable tapered metering valve to provide needle-point control of air flow on pressure (exhaust) applications as well as for vacuum relief on vacuum systems.
- Air flow is metered between fully closed and fully open using an external adjustment screw
- Locknut allows desired setting to be locked in to prevent accidental changes.
Material and Application:
- Constructed of 40 Micron sintered porous bronze and zinc-plated steel
- Durable and superior noise reduction and air flow control.
PSI pressure service recommendation: up to 125 psi (8.6 Ba
