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.

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

Relieve heat and moisture buildup in enclosures and other small spaces.

A spring-loaded fusible link locks the blades closed if the temperature reaches 167° F. Louvers meet UL 10C fire requirements.

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.

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

Cover the opening where air is pulled into your HVAC system.

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

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

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.

The expanded mesh on these vent caps provides spark protection.

These breather vents withstand corrosion in damp environments.

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

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.

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

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.

Adjust flow by turning the screw, then tighten the hex nut with a wrench to secure.

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

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.

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.

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.

Also known as thermostatic steam traps, these increase the efficiency of your radiator by venting cool air.

Suitable for food, pharmaceutical, and other sanitary environments, these steam traps are made of 316 stainless steel with a Viton® fluoroelastomer O-ring to stand up to frequent washdowns with harsh cleaners and sanitizers.

For the highest level of protection from water, these vents rated IP68 for protection from water submersion.

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

Mount these drains at the bottom of your enclosure to let moisture drip out and keep electronics dry.

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.

Eliminate air pockets in your drinking water system with these valves. They meet NSF/ANSI 61, which designates them as safe to use with drinking water.
