PRICE PDDR / PDDRE Series perforated face return air ceiling diffusers are designed to match supply air models PDN and PDF in appearance and detail, except that air pattern controllers are not required. The PDDR series is offered in two versions — one for ducted return and one for plenum return applications. For ducted return air applications, PDDR features the same backpan as the supply air models, providing a connection to a flexible or rigid round duct, or to a square or rectangular duct. For plenum return (non-ducted) applications, a special frame assembly results in an inlet 2 in. [51] under module size for maximum free area. The drop (extended) face Model PDDRE is available to complement the supply air models PDNE, PDCE and PDFE for tegular tile ceilings.
For Fire-Rated applications see Series
PDDR-FR / PDDRE-FR.
