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.

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.

Place these grilles in the grid of a drop ceiling.

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

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

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

Join duct and fittings with quick-release clamps for faster disassembly and cleanout than other duct systems.

A spiral seam gives this duct greater strength and rigidity than standard duct.

Often used in tight spaces, such as in walls and ceilings, rectangular duct allows you to select larger sizes without increasing duct height.

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.

Always open, these are our most basic wall louvers.

Mount these louvers into openings that are too small for most louvers. They are sized for use in block and brick walls.

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.

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

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

These louvers are gravity operated. The blades open when your roof-mounted exhaust fan goes on and close when it's off, preventing backdrafts.

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

Suitable for use with welding equipment, these mufflers are made of flame-resistant materials. They reduce noise by 35 dB.

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.

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.

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.

These mufflers can be cleaned for an extended service life.
