Enclosure Louvers
Relieve heat buildup and prevent condensation from forming inside enclosures and other small spaces.
All aluminum louvers have small openings between their blades to stop bugs from getting inside your enclosure. Anodized aluminum louvers withstand corrosion better than unfinished and powder-coated aluminum louvers. They’re good for settings such as saltwater environments. Darkroom louvers have a shield on the back that blocks out light—use them where light control is a concern.
Powder-coated steel and 316 stainless steel louvers are rugged and durable.

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.
