Place these grilles in the grid of a drop ceiling.

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

These dampers regulate airflow.

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

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.

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.

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

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.

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

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.

Keep rain and debris out of vertical exhaust pipe with these caps that open with slight pressure from exhaust.

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

Safe for use around flammable and combustible gases, vapors, fibers, and dust, these vents allow air to flow through enclosures to maintain consistent pressure and reduce moisture buildup as temperatures change. They also stand up to washdowns.

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.

Filters remove dust and other particles from the air.

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

These two-piece guards attach to NEMA frame motors.

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

Protect against excess vacuum and pressure in cylinders, gear boxes, enclosures, manifolds, and tanks.

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

Minimize moisture buildup in enclosures. Also known as drain plugs, these breather vents have a small outlet that allows condensation to drain.

Body is brass or nickel-plated brass. All meet ASME Code Section VIII for use with air and inert gas pressure vessels.

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.

Use these valves with liquid argon, liquid nitrogen, and liquid oxygen.

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

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

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.

These valves have a cast iron body.

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.
