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.
USAB air intake/exhaust port 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.
