No need for clamps or connectors—duct and fittings have a male end that is slightly smaller than its female end for simple assembly.

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

Fittings have gaskets which create a tight seal—you don't need to seal joints with coating or tape.

These dampers regulate airflow.

No additional fittings or collars needed.

No additional fittings or collars needed.

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.

Regulate airflow by adjusting dampers from fully open to fully closed.

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

These gravity-operated louvers remain open only when air flows, preventing backdrafts.

Always open, these are our most basic wall louvers.

Constructed with a thick frame and blades, these louvers have a long service life.

Designed with blades that drain water down the jambs, these louvers keep water from running down the front of the blades, even in harsh weather.

Fixed front blades give you consistent sight lines when viewing these louvers from outside, while hidden rear blades open and close.

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

For use with gas-fired equipment, such as boilers and furnaces, these vent pipes and fittings withstand temperatures up to 400° F. Also known as type B gas vents.

The expanded mesh on these vent caps provides spark protection.

The arm length adjusts from 3 to 6 feet making these exhaust hoses good for locations with low ceilings.

Move the hose into position and the support arm will hold it in place.

Position these exhausters above drums, tanks, and distillers.

In addition to using the handle to carry these exhausters, you can mount them to a wall, bench, or floor.

This fume exhauster has a motor that is UL listed for Class I, Divisions 1 and 2, Groups C and D; and Class II, Divisions 1 and 2, Groups E, F, and G locations. Use it to remove fumes, vapors, and fine dust particles from your space.

Increase airflow through exhaust duct to improve furnace performance.

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

Better suited for dirty, dusty, and damp environments than standard direct-drive fans, these have a totally enclosed motor enclosure.

These fans come complete with a movable-blade louver. The louvers are gravity operated so they open only when air flows through them, which prevents backdrafts.

Better suited for dirty, dusty, and damp environments than standard belt-drive fans, these have a totally enclosed motor enclosure.

Good when you don't have room to mount an exhaust fan inside your facility, these fans attach to an outside wall and work with or without duct.

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

Direct-drive fans have fewer moving parts than belt-drive fans for less maintenance.

Exhaust air and humidity directly into the outdoors without using duct.

Use these fans to draw stagnant and humid air out of a room.

Insert these fans directly into your ductwork. They give small heaters and air conditioners a boost to circulate air through ductwork.

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