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.

These vents maintain air pressure inside enclosures that may be exposed to indoor and outdoor temperature changes while keeping dust and water out.

These vents have louvers with foam filters to keep out dust and falling liquids.
