Linear Bar Grille

Type LBG39 & Type LBG66

The LBG series grilles are designed to be used in air conditioning systems for either heating or cooling or a combination of both. The distance between the blades allows for either 50 or 75 percent free area and the units can be strengthened for use in public areas such as gymnasiums.

They can be placed in ceilings, floors or as continuous line units or small separate units for fan coils. They are also suitable for slim line applications above radiators.

Removable cores are an option as are hinged cores and removable sections.
