These dampers regulate airflow.

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

Connect diffusers to duct.

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.

Place these grilles in the grid of a drop ceiling.

Use these louvers in harsh environments—they won't rust.

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.

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.

Replace your muffler less often—these have a filter design that stays clean longer than porous mufflers.

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

Also known as reclassifiers, these mufflers have a clear reservoir with a drain plug to remove and store oil mist for reuse.

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

Suitable for use with welding equipment, these mufflers are made of flame-resistant materials. They reduce noise by 35-42 dB.

A rubber air diffuser provides uniform bubble distribution.
