Mufflers

Use these mufflers with air-powered tools, valves, and cylinders to reduce noise and filter exhaust fumes.

High-Flow Mufflers

Commonly used with high-flow, air-powered equipment, such as diaphragm pumps and valves, these mufflers reduce noise and filter exhaust fumes without restricting flow.

Compact High-Flow Mufflers

A small hex size makes these high-flow mufflers a great fit for cramped spaces.

Flow-Control Mufflers

Adjust the flow by turning the screw. Use these mufflers with air-powered tools and cylinders to reduce noise and filter exhaust fumes.

Corrosion-Resistant Mufflers

Made entirely of stainless steel, these mufflers stand up to harsh, corrosive environments.

Clog-Resistant Mufflers

Replace your muffler less often—these have a filter design that stays clean longer than porous mufflers.

Easy-to-Clean Mufflers

These mufflers can be cleaned for an extended service life.

Inline Mufflers for Air and Inert Gas

With a threaded connection on both ends, these mufflers can be installed anywhere in your line.

Oil-Mist-Eliminating Mufflers for Air and Inert Gas

In addition to a filter, these mufflers have a wool felt disc to trap oil mist.

Oil-Mist-Recycling Mufflers

Also known as reclassifiers, these mufflers have a clear reservoir with a drain plug to remove and store oil mist for reuse.

High-Noise-Reducing Mufflers

Install these mufflers in air-powered drills and other loud equipment. They filter exhaust fumes and reduce noise by 30 dB, a reduction that's equivalent to putting in earplugs.

Flame-Resistant High-Noise-Reducing Mufflers

Suitable for use with welding equipment, these mufflers are made of flame-resistant materials. They reduce noise by 35 dB.

Clog-Indicating High-Noise-Reducing Mufflers

Don’t let an unexpected clog interrupt your work. These mufflers have a filter that slides up slowly as it clogs to indicate when the muffler should be replaced. They reduce noise by 30-35 dBA

Exhaust Filters/Mufflers for Dry High-Vacuum Pumps

Purify exhaust fumes while silencing the noise from your oil-free high-vacuum pumps.
