These valves are made of corrosion-resistant materials for use in wet conditions and harsh environments.

For excellent corrosion resistance in wet conditions and harsh environments, these valves have no metal parts.

Turn the key to manually vent radiators and heaters.

Our only air-release valves for steam, these seal shut when steam enters the valve to prevent system contents from escaping through the relief port.

Add a filter to these grilles for protection against dust and debris entering your HVAC system.

No additional fittings or collars needed.

These dampers regulate airflow.

A vapor barrier provides moisture protection as these diffusers spread hot or cold air around a room.

Diffusers come with a collar and damper already in place for simple installation.

Direct air coming out of HVAC systems. Adjust the damper to control airflow.

Guide air toward your workspace or deflect unwanted drafts with these diverters and covers.

Join duct and fittings with quick-release clamps for faster disassembly and cleanout than other duct systems.

Also known as barometric dampers, these dampers improve furnace performance by automatically opening and closing to maintain consistent airflow despite changing environmental conditions.

In the event of a fire, these dampers automatically stop airflow through duct.

Mount these louvers into openings that are too small for most louvers. They are sized for use in block and brick walls.

The included filter cleans the air as it passes through these louvers.

Get an exact fit for your opening by sliding out these louvers to the width you need.

Thicker than standard movable-blade wall louvers, these are rugged and dependable.

Relieve heat buildup and prevent condensation from forming inside enclosures and other small spaces.

Allow air to circulate through doors while maintaining privacy.

These louvers are gravity operated. The blades open when your roof-mounted exhaust fan goes on and close when it's off, preventing backdrafts.

Cover chimneys to reduce downdrafts and prevent obstructions from entering.

Built to withstand temperatures up to 1000° F, these vent pipes and fittings are for use with boilers, furnaces, stoves, and other equipment that is fired by coal, gas, oil, propane, or wood.

These breather vents withstand corrosion in damp environments.

These breather vents are rated NEMA 6 to withstand periodic submersion in water.

Add a filling port to your hydraulic tank while protecting against excess pressure and vacuum.

Keep moisture, dirt, and debris from entering your oil reservoirs.

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

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

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

These mufflers can be cleaned for an extended service life.

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.

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

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

Mount to the outside of your enclosure to prevent moisture from being trapped inside.

These conductive aluminum screens block electromagnetic interference (EMI) and radio frequency interference (RFI) to prevent electrical problems such as radio static and faulty signals. Made of mesh, they let air flow through, so the pressure in your enclosure stays constant as temperatures fluctuate.

Vent air from your enclosure to equalize pressure and stop condensation from forming inside while securing cords in wet environments. These polyamide grips are lightweight and resist rusting.

Belt-drive fans are quieter and have a longer life span than direct-drive fans because components can be replaced if worn or damaged.

Direct-drive fans have fewer moving parts than belt-drive fans for less maintenance.

These hoods keep your enclosure watertight, even around intake and exhaust cutouts.
