External stainless steel ventilation grille

 

USUF external grilles are stainless steel products designed for
wall mounting with screws.

The deep sleeve-like bezel and the dipped-down louvres
protect from the ingress of melt water
and rain, while the removable wire mesh keeps insects away.

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.

ULMA decorative air grilles can be used as an air intake or exhaust vents
and have been specifically designed for use in single-family
houses. They are made from cast aluminium with an
ornamental bezel and spoke finish.

The sturdy casting form can withstand typical loads when installed as a floor vent.
The inward sleeve of the grille fits spiral coiled ducts and other
types of round ventilation ducts. The sleeve features a wire
mesh which is easily removable for cleaning.

SGR air supply/exhaust grilles are installed directly and
lengthwise on the round ducts and fastened with screws.
The grille has been designed so that the bezel flange fits
tightly to the round surface of the duct, whatever the duct
diameter.

The grille is made of galvanized steel sheet without
tack or seam welds. As a result, it requires no anti-corrosion
protection and its finish matches that of the ductwork. The
grille can be optionally fitted with single or double louvre
blades positioned horizontally and vertically. The louvre blade
angle is adjusted manually. The air grille can also be fitted
with the SGR-DA sliding angle damper.

The SGR-DA sliding angle damper is designed for installation
on the SGR air grilles intended for round ventilation ducts. The
damper is provided with separate clips for mounting on the
air grille.

The SGR-DA dampers provide a means to control the
air flow rate, air flow speed and air flow range. The damper
outlet grate is set at an angle to the air grille surface. The air
flow is adjusted by repositioning the damper closure behind
the damper grate.
