The LTD diffusers to provide superior horizontal air distribution at low sound levels when interfaced with compatible air handling light fixtures. The LTD series can be factory coordinated to accommodate the normal slot configurations of either surface slot or regressed slot air handling light fixtures.

Model LTD air troffer diffuser has been with a curved pattern controller which provides a superior horizontal air pattern, resulting in optimum space air distribution. The horizontal air pattern is ideal for general air conditioning applications. The horizontal air pattern produces the maximum entrainment of room air, generating the air motion required to provide the optimum comfort conditions throughout the occupied zone.

The consistent horizontal air pattern eliminates the need for the installer or balancing contractor to adjust the pattern controller to avoid vertical air discharge. This performance feature eliminates vertical air discharge pattern, the most frequent source of complaint of draft conditions in occupied zones, when field setting of adjustable pattern controllers has been overlooked.

These diffusers attach quickly and easily to standard fluorescent light troffers. Lighting and air distribution are provided through one ceiling penetration. The air opening is an inconspicuous slot at the edge of the light troffer. The LTD diffusers are compatible with most manufacturer's models of light troffers and are suitable for surface slot and regressed slot applications.

Single Side Model This Model is designed to provide concealed air distribution from one side of a light troffer. The diffuser incorporates curved blade pattern controller, adjustable from the air supply slot, which provides a consistent horizontal air discharge pattern at low sound levels.

Diffusion are available with uninsulated construction, externally insulated and internally insulated.



Saddle Model This model is designed to provide concealed air distribution from two sides of a light troffer. The diffuser incorporates curved blade pattern controller, adjustable from the air supply slot, which provides a consistent horizontal air discharge pattern at low sound levels. Air pattern controller can be adjusted for trim balancing to equalize the air flow from each side of the diffuser.

Diffuser are available with uninsulated construction externally insulated and internally insulated.
