Model ALT light troffer diffusers are factory co-ordinated to accommodate the normal slot configurations of light fixtures.

ALT Light Troffer Diffusers have been designed with a pattern controller which provides an excellent horizontal air pattern, resulting in optimum space air distribution.

With a superior horizontal air pattern, it produces the maximum entrainment of room air, generating the air motion required to provide the optimum comfort conditions throughout the occupied zone.

• AIR GRILLES light troffer diffusers are custom made to suit all light fitting designs.
• For top entry, the collar is round in shape and side entry, oval in shape.
• Internally insulated with ½ 31bs fibreglass.
• Butterfly damper will be installed at the collar if required.
• Air discharge pattern can be adjusted from face of the troffer air slot.
• Designed to handle large volumes of air quietly and efficiently.
• Units of diffusers have been tested at an independent N.A.T.A. accredited test laboratory in Australia.
