Weather-Resistant Enclosure Louvers
With a gasketed sealing kit, these louvers shield your enclosure from dirt, moisture, and weather while regulating heat and stopping condensation from forming inside. All have an aluminum mesh filter that keeps out solid debris and water.
Stainless steel louvers stand up to corrosion better than powder-coated steel louvers.

EMI/RFI-Shielding Enclosure Vents
These conductive aluminum screens block electromagnetic interference (EMI) and radio frequency interference (RFI) to prevent electrical problems such as radio static and faulty signals. Made of mesh, they let air flow through, so the pressure in your enclosure stays constant as temperatures fluctuate.
Screw through the vent frame to mount on the surface of your enclosure. A shielded foam gasket fills the gap between the enclosure and the vent.
Also known as attenuation, interference reduction at frequency measures how much interference is blocked. These vents have high attenuation and work for most applications.

Enclosure Intake and Exhaust 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.
