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.

TYPE 3300

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

Design Features:

Type 3300 Louvers 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 may be stacked.
