Mufflers

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

Compact High-Flow Mufflers

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

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.

Corrosion-Resistant Mufflers

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

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.

Easy-to-Clean Mufflers

These mufflers can be cleaned for an extended service life.

Clog-Resistant Mufflers

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

Oil-Mist-Eliminating Mufflers

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

Inline Mufflers

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

End-Exhaust Mufflers

These mufflers exhaust through narrow holes on one end to provide a concentrated blast of air. Use them to eject items from your conveyor and direct exhaust away from delicate applications.

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 30-35 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 35-42 dB.

Inline High-Noise-Reducing Mufflers

With a threaded connection on both ends, these mufflers can be installed anywhere in your line. They reduce noise by up to 45 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 dB.

Intake and Exhaust Filters

Air-Intake Filters

Stop dust and other contaminants from entering your process and equipment. Use these filters on blowers, compressors, engines, and in hydraulic systems.

Compact Air-Intake Filters

Clean the air going into small blowers and air-powered equipment in tight spaces.

Corrosion-Resistant Air-Intake Filters

Made of polypropylene, these filters can be used in damp environments where corrosion is a concern.

Inline Air-Intake Filters

With a threaded connection on both ends, these filters can be installed anywhere in your pipeline to keep dust and debris out of your system.

Exhaust Filters/Mufflers for Dry High-Vacuum Pumps

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

Air-Exhaust 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.

Made-to-Order Air-Operated Air-Exhaust Control Valves

Choose the pressure range you need. When these valves receive an air signal, they quickly dump exhaust air to the atmosphere without routing it back through a directional control valve to speed up the movement of equipment. They're often used with air compressors that require continuous operation. Also known as quick exhaust valves.

Elbow Air-Exhaust Control Valves with Flow Control

Control the flow of exhaust air while also regulating the exhaust air speed. These valves dump exhaust air to the atmosphere without routing it back through a directional control valve. The 90° elbow shape allows you to install them in tight spaces. Also known as quick exhaust valves.

Quiet Air-Exhaust Control Valves

A muffler reduces exhaust noise. Valves allow airflow into your equipment and then quickly dump exhaust air to the atmosphere without routing it back through a directional control valve to speed up the movement of equipment. Also known as quick exhaust valves.
