Inlets shall be round or oval, centrally located, with a minimum depth of 2 1/8" for ease of duct connection. Units with inlet depths less than 1-3/4" are not acceptable. For straightness and rigidity, plenums shall be fabricated using a single–piece panel construction and have a double metal thickness hem at the face. Plenum diffusers shall be constructed of corrosion resistant galvanized steel. Height of unit shall be 10" or greater to maximize diffuser performance.

Units with heights less than 10" are not acceptable.

Units shall be available with 1/2", 3/4", 1", or 1-1/2" slot widths and be available with 1, 2, 3, or 4 independent supply slots. Diffuser face and air pattern controller shall be black. Optional tees shall be white.
