The DIF.P, DIF.A and DLS.A terminal hoods enable the installation of absolute filters directly into sterile and cleanroom environments, thus diffusing the air filtered to the required purity levels directly into the room.
They are made of a frame to hold a DELTA mini-pleat absolute filter, a thermoformed polystyrene plenum and a diffuser. The diffuser can be unidirectional flow, high induction swirl flow or 4-way turbulent flow with Coanda effect. Filter and diffuser can be disassembled directly from inside the room.
