Louvers, Dampers, & Industrial Grilles
|
 Louvers
Our standard weather louvers are
die-formed .050 aluminum with removable external expanded
aluminum screens. Available in sizes up to 52” wide
and 123” tall. They make an excellent installation
companion with our type “A” dampers for outside
and exhaust applications.

Dampers
 Our
type “A” dampers have die-formed. galvanized angle
frames with crank arms and linkage out of the airstream.
They can be surface mounted, eliminating the need for a
louver sleeve. Stainless steel construction is available,
as are operator mounting brackets with linkage kits. Our
type “R” dampers are barometric relief dampers
designed to relieve internal building pressure.
They're designed for stiffness and wear resistance.

Industrial
Grilles
Grilles are fabricated in two parts: the
frame and core. These sturdy grilles require no rebalancing once
in place. Practically maintenance free, they have no springs or
other devices to fail. Specifically designed for use in dirty
environments requiring large volumes or air. The two-part frame
design is for easy removal for cleaning. Frames are extruded aluminum
welded in the corners. Cores have a die formed aluminum wrap and
extruded aluminum binder.
