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.

Oil-Mist-Eliminating Mufflers

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

Clog-Resistant Mufflers

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

Inline Mufflers

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

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.

Air-Powered Vibrators for Dry Materials

These are also known as ball vibrators.

Energy-Efficient Air-Powered Vibrators for Dry Materials

Also known as turbine vibrators, these use half the air of other air-powered vibrators to generate the same force.

Air-Powered Vibrators for Wet Materials

Also known as piston vibrators, these pound the sides of your bin to dislodge wet, sticky, and caked-on materials.

Compressed Air Control Valves

Air-Exhaust Flow Control Valves

Install these valves in the exhaust ports of air directional control valves to control exhaust air speed without needing access to your cylinder.

Quiet Safety-Lockout Air On/Off Valves

These valves have a muffler to reduce exhaust noise. A padlock locks the handle in the shut-off position so you can disconnect air tools safely.
