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.

Place these diffusers in the grid of a drop ceiling to distribute air evenly throughout your space.

Connect diffusers to duct.

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

Evenly disperse airflow into a room to maintain a consistent temperature throughout the space.

Install onto floor ducts to direct hot and cold air from your HVAC system.

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

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

No need for clamps or connectors—duct and fittings have a male end that is slightly smaller than its female end for simple assembly.

Constructed with a thick frame and blades, these louvers have a long service life.

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

Mount these louvers through an outside wall and control airflow from the inside by adjusting the register.

These gravity-operated louvers remain open only when air flows, preventing backdrafts.

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.

The expanded mesh on these vent caps provides spark protection.

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.

Shield outdoor pipe and tank openings from the environment. Also known as vent caps, these breather vents have screens to allow air flow while blocking debris.

Secure access to vented openings in pipe and tanks—the cap can be locked to prevent tampering.

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

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

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.

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

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

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

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

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.

Use these vents to maintain consistent pressure as temperatures fluctuate by allowing air to flow through sealed enclosures.

No threaded hole or tools needed—snap these vents into enclosures with a maximum 1/8” panel thickness to let airflow in and keep water out even when submerged.

Rated NEMA 4X, these vents provide protection from washdowns, corrosion, and power jets of water.

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.

Secure cable installed through enclosures in wet environments while venting air to protect electronics from condensation.

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

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.
