Type 3200

The increasing heat loads in industrial structures caused by today’s huge modern furnaces and other heat producing equipment require greater ventilation exhaust capabilities and, in turn, more efficient air inlet.

Design Features

Strong and efficient, the Type 3200 Industrial Operating Louvre has up to 85% effective free area opening, with a minimum static pressure drop. The blades are housed in a rugged 2.5mm thick galvanised steel frame, painted or unpainted, which make it ideally suited to industrial applications. Normal operation is by means of spring and cable; however, optional hand or chain wheel, electric motors, or other methods are available to operate the louvres singly or in banks.

Type 3300

Type 3300 louvres feature rugged, heavy gauge materials, factory controlled fabrication and accurate forming. The materials give the designer freedom to blend or contrast the louvres with surrounding areas.

Design Features

Type 3300 louvres are designed so that in the fully open position the blades and the hand operating mechanism do not project beyond the louvre joints. When open, the louvres produce minimum pressure drop, with good resistance to weather penetration. When fully closed, air infiltration is reduced to a minimum.

Louvres are designed for either single louvre application to small openings or, where necessary, multiple louvre application. Louvres can be stacked vertically in banks with suitable supporting steelwork.

Standard Louvre Heights (mm)

* Denotes minimum dimensional limitation.
NOTES:
a) Standard heights shown give maximum free inlet area; however,
louvres can be manufactured to suit any opening dimensions.
b) Nominal weight in steel (with Standard Operating System): Type 3200 = 16 kg/m2; Type 3300 = 17.5 kg/m2.
