No need for clamps or connectors—duct and fittings have a male end that is slightly smaller than its female end for simple assembly.
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.
Made of PVC plastic to withstand acids, alkalies, salts, and other corrosive vapors and fumes.
Fittings have gaskets which create a tight seal—you don't need to seal joints with coating or tape.
Often used in tight spaces, such as in walls and ceilings, rectangular duct allows you to select larger sizes without increasing duct height.
These dampers regulate airflow.
Connect diffusers to duct.
No additional fittings or collars needed.
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.
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.
Cover the opening where air is pulled into your HVAC system.
Place these grilles in the grid of a drop ceiling.
Add a filter to these grilles for protection against dust and debris entering your HVAC system.
Install onto floor ducts to direct hot and cold air from your HVAC system.
Regulate airflow by adjusting dampers from fully open to fully closed.
Save energy and increase comfort by heating and cooling only the areas that need it.
Also known as barometric dampers, these dampers improve furnace performance by automatically opening and closing to maintain consistent airflow despite changing environmental conditions.
In the event of a fire, these dampers automatically stop airflow through duct.
Add a flexible joint to your system to reduce vibration caused by fans and blowers.
These gravity-operated louvers remain open only when air flows, preventing backdrafts.
Made of PVC, these louvers stand up to acids, alkalies, salts, and corrosive vapors in harsh environments and won’t rust.
Always open, these are our most basic wall louvers.
Sized to replace block or bricks.
Constructed with a thick frame and blades, these louvers have a long service life.
Get an exact fit for your opening by sliding out these louvers to the width you need.
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.
The included filter cleans the air as it passes through these louvers.
Fixed front blades give you consistent sight lines when viewing these louvers from outside, while hidden rear blades open and close.
Relieve heat buildup and prevent condensation from forming inside enclosures and other small spaces.
With a gasketed sealing kit, these louvers shield your enclosure from dirt, moisture, and weather while regulating heat and stopping condensation from forming inside.
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.
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.
Cover chimneys to reduce downdrafts and prevent obstructions from entering.
The expanded mesh on these vent caps provides spark protection.
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.
Keep rain and debris out of vertical exhaust pipe with these caps that open with slight pressure from exhaust.
The arm length adjusts from 3 to 6 feet making these exhaust hoses good for locations with low ceilings.
For exact positioning, these hoses swivel 360°.
Move the hose into position and the support arm will hold it in place.
Remove fumes, vapors, and fine dust particles from your space.
Position these exhausters above drums, tanks, and distillers.
Mount these exhausters to the floor to remove fumes, vapors, and fine dust particles from your space.
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.
Often used for electric-to-gas conversions and renovations, these exhausters allow gas- or oil-fired equipment to be vented through a sidewall rather than a chimney.
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 light duty fans are designed for use without duct.
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.
Belt-drive fans are quieter and have a longer life span than direct-drive fans because components can be replaced if worn or damaged.
Better suited for dirty, dusty, and damp environments than standard belt-drive fans, these have a totally enclosed motor enclosure.
Use these fans to draw stagnant and humid air out of a room or area. Belt-drive fans are quieter and have a longer life span than direct-drive fans because components can be replaced if worn or damaged.
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.
Designed to spin freely with the slightest breeze, these fans create a vacuum that draws air out from buildings and ventilation systems—no electricity required.
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.
Also known as room-to-room exhaust fans, these exhaust air and humidity directly into another room.
Use these fans to draw stagnant and humid air out of a room.
These fans have a light that can operate alone or share a switch with the fan.
Keep noise to a minimum with 1/2" thick acoustical insulation and vibration-resistant motor mounts.
These fans have a motor that is UL listed for hazardous environments.
Insert these fans directly into your ductwork. They give small heaters and air conditioners a boost to circulate air through ductwork.
Often used in vehicles, these fans operate on DC power.
Produce three times the airflow as standard direct-drive duct fans.
These hoods keep your enclosure watertight, even around intake and exhaust cutouts.
