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.

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

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

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.

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

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

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.

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.

Direct-drive fans have fewer moving parts than belt-drive fans for less maintenance. Use these fans to draw stagnant and humid air out of a room or area.
