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

The expanded mesh on these vent caps provides spark protection.

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.

Also known as sintered filters and frits, these discs have tiny holes that trap very small particles. Discs are often used in laboratories and gas-bubbling applications (sparging).

Also known as thermostatic steam traps, these increase the efficiency of your radiator by venting cool air.

When close to steam temperature, these traps—also called thermodynamic steam traps—release condensate from steam lines to save energy in food, pharmaceutical, and other sanitary environments.

Safe for use around flammable and combustible gases, vapors, fibers, and dust, these vents allow air to flow through enclosures to maintain consistent pressure and reduce moisture buildup as temperatures change. They also stand up to washdowns.
