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.

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.

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.

Place these grilles in the grid of a drop ceiling.

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.

Made of PVC plastic to withstand acids, alkalies, salts, and other corrosive vapors and fumes.

Save energy and increase comfort by heating and cooling only the areas that need it.

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

Use in dust collection systems. The slide pushes through the top of the gate to clear debris.

More convenient than other blast gates, these automatic gates open and close in sync with dust collectors, fume exhausters, and other machines.

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.

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.

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

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

These mufflers can be cleaned for an extended service life.

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

Install these mufflers in air-powered drills and other loud equipment. They filter exhaust fumes and reduce noise by 30 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 dBA

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

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

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 thermodynamic steam traps, these discharge condensate when close to steam temperature for minimal energy loss.

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

These steam traps offer good corrosion resistance.

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

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

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.

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.

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.

For a low-pressure seal around plastic and soft metal tubing, these valves have push-to-connect fittings.

Change set pressure without guesswork—the adjustment screw is marked in 25 psi increments for making pressure adjustments without a gauge.

Design a valve specifically for your process media and set pressure. Choose from a valve for air, inert gas, water, hydraulic oil, fuel oil, gasoline, or diesel fuel and a set pressure.

To gradually relieve pressure in lines for diesel fuel, fuel oil, gasoline, and kerosene, these valves begin opening at the set pressure and fully open at about 10% over the set pressure.

These valves are often used with catalysts, pH buffers, and electroplating solutions.

Cleaned and bagged for oxygen service and other high-purity applications, these valves are built to withstand the extreme cold of liquid carbon dioxide, liquid nitrogen, and liquid oxygen.

The most basic option for air and inert gas applications.

For corrosion resistance in wet conditions and harsh environments, these valves have a 303 stainless steel body. All meet ASME Code Section VIII for use with air and inert gas pressure vessels.

These valves have a bronze body for durability and a long service life. All meet ASME Code Section VIII for use with air and inert gas pressure vessels.

Commonly used with high-volume blowers, compressors, and air-powered conveyors, these valves quickly relieve a large amount of air in systems with a pipe size of 2 or greater. All meet ASME Code Section VIII for use with air and inert gas pressure vessels.

Our only valves that meet ASME Code Section VIII for use with cryogenic pressure vessels. They are for use with argon, carbon dioxide, helium, hydrogen, methane, nitrogen, and oxygen.

These valves meet ASME Code Section I for use with steam power boilers requiring pressure relief above 15 psi.

For use with low-pressure steam-heating boilers requiring pressure relief at 15 psi, these valves meet ASME Code Section IV.

Protect your water-heating system with these valves that meet ASME Code Section IV for hot water heaters and boilers.

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 light duty fans are designed for use without duct.

Rust won't be a problem with the durable plastic housing and louvers on these fans.
