Heavy-Duty Mufflers for Pumps — 2" NPT / 2.5" NPT / 3" NPT / 4" NPT / 5" Flange
Industrial-grade inline mufflers for vacuum pumps and blowers. Designed to reduce broadband discharge/intake noise while maintaining airflow with minimal pressure drop. Heavy-gauge steel housings with serviceable acoustic packs for long life in dairy and light-industrial applications.
What’s included:
- Complete heavy-duty muffler assembly (pre-installed acoustic pack)
- Integrated drain/boss (where applicable)
Not included:
- Piping, adapters, gaskets, flange hardware, thread sealant, or mounting brackets (sold separately)
Fit/Use Notes: Match muffler connection to your pump/blower outlet or inlet (NPT thread or 150-lb class flange). Install as close to the machine as practical with straight run-in/out for best attenuation and lowest pressure drop. Always support the muffler weight independently of the pump.
Benefits
- Noise reduction – Broad-spectrum attenuation to improve operator comfort.
- Durability – Thick-wall steel body with corrosion-resistant finish.
- Serviceable – Bolt-on end cap for media inspection/replacement.
- Low restriction – Large-area internals to minimize backpressure.
