Air Intake/Exhaust Port with Wire Mesh

USAB air intake/exhaust ports are used to terminate ductwork ends in mechanical, gravity or heat-recovery ventilation systems. Unlike louvre blades, the wire mesh generates very low air flow resistance while protecting against the ingress of dry leaves, debris or birds into the ductwork. The product is made from stainless steel, and the gasket underneath is made from EPDM rubber and provides a tight and snug fit to the wall. The inward part of the port fits spiral coiled ducts and flexible ducts.
