1 Square and Rectangular Directional Diffusers Product Overview Price offers a complete line of square and rectangular directional diffusers for a velocity of. Models SMD / AMD This series of louvered face directional diffusers is available in steel (SMD) and aluminum (AMD) construction with a wide variety of air pattern core styles in square and rectangular neck styles. They can supply large volumes of air at low sound levels and pressure drops. Complete with a wide selection of frames for flush, T-bar and drop mounting, the SMD / AMD is the diffuser of choice for most architectural applications. Models SMDA / AMDA Matching the styling of the SMD / AMD line of diffusers, these are designed for field adjustment from horizontal to vertical air pattern and are available in steel (SMDA) or aluminum (AMDA) construction. Models SMX / AMX Matching the styling of the SMD / AMD line of diffusers, these are designed for high induction and rapid mixing with the addition of internally mounted discharge vanes. Model SMDP The SMDP design is intended to blend harmoniously with most ceiling systems while the louvered slots supply large volumes of air at relatively low sound levels and pressure drops. Models AMDSR / CSRD These combination supply / return directional diffusers are available in louvered face extruded aluminum construction (AMDSR) as well as aluminum egg crate core (CSRD) return air sections. Models SMCD / AMCD / AMCDP Designed for air pattern adjustment through field modification of louvered modular pattern controllers, PRICE modular core directional diffusers are available in steel (SMCD) and aluminum (AMCD) construction, as well as with a perforated face panel version (AMCDP) for smooth integration with the ceiling. Model CVD / SCVD / ACVD Individually adjustable curved vanes direct supply air precisely to suit the desired application in PRICE model CVD/SCVD/ACVD directional diffusers. A clean, functional appearance with excellent performance characteristics, the CVD/ SCVD/ACVD provides a wide range of application versatility.

3 Louvered Face Directional Diffusers CSRD Series Combination Supply / Return Product Information PRICE CSRD Series combination supply / return directional diffusers are available with extruded aluminum louvered blades for supply air and an egg crate core for return air. Extruded aluminum construction matches in detail and styling the Series AMD. The performance characteristics are excellent; the diffuser handles a large amount of air for a given set of outside dimensions with low pressure drop and noise levels. The CSRD is sized to match rooftop air conditioners in the most popular capacities. Features Extruded aluminum construction. Return air core is aluminum egg crate, minimizing see through and maximizing free area Surface mounting flange is applicable to most ceiling types. Finish White Powder Coat B12 For optional and special finishes see color matrix.
