Intake and Exhaust Enclosure Hoods

Image of Product. Front orientation. Contains Annotated. Enclosure Hoods.

These hoods keep your enclosure watertight, even around intake and exhaust cutouts. The silicone seal shuts out water and dust, while the slanted top lets water roll off. When used over fans or vents rated IP54 or higher, hoods meet IP56 and NEMA 4X to help protect your electronics from wet and corrosive environments, dust, and washdowns. They also meet American, Canadian, and European safety standards.

Screw the mounting bracket around your fan or vent, then clip the hood on. Pop it off for cleaning, changing filters, and other maintenance.

Standard Duct and Fittings

Deliver air for a range of HVAC applications, including exhaust and dust collection. Our basic duct, the round shape creates smoother, more efficient airflow than rectangular and oval duct. The male end is slightly smaller than the female, so sections join without clamps or tools.

Rain Caps

Top off vertical duct and exhaust stacks to prevent corrosion and blockages that can disrupt airflow.

Galvanized Steel—Corrosion resistant and affordable, galvanized steel is the most commonly used ductwork material.

Corrosion-Resistant 304 Stainless Steel—The most corrosion-resistant metal duct we sell. It won’t rust or degrade in systems that exhaust chemical fumes or vent heat from industrial ovens and dryers.
