With a gasketed sealing kit, these louvers shield your enclosure from dirt, moisture, and weather while regulating heat and stopping condensation from forming inside.

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.

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.

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.

These dampers regulate airflow.

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

No additional fittings or collars needed.

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

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.

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.

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.

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

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

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.

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.

Shield vents on electronic and automotive equipment, such as cell phone microphones, from water, dirt, and debris without blocking them entirely.

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.

Also known as thermostatic steam traps, these vent cool air and condensate to increase energy efficiency in your steam lines.

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

These vents maintain air pressure inside enclosures that may be exposed to indoor and outdoor temperature changes while keeping dust and water out.

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.

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.

Safe for use around hazardous gasses and dust, these vents maintain steady pressure and prevent moisture buildup from temperature changes inside enclosures.

Safe for use around flammable and combustible gases, vapors, fibers, and dust, these drains let moisture buildup from temperature changes inside enclosures drip out to keep electronics dry.

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

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.

An internal wire brush traps air bubbles and discharges them through the top relief port while allowing inline flow from the inlet to the outlet.

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.

Designed to spin freely with the slightest breeze, these fans create a vacuum that draws air out from buildings and ventilation systems—no electricity required.

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