Direct vent MDO 4-way diffuser 450 x 450mm, supply air (SR45)

Direct vent MDO 4-way diffuser 450 x 450mm, supply air (SR45)

This direct vent MDO diffuser is a 4-way multi directional diffuser with a 450 x 450mm face, listed for supply air only. Its matt face with high gloss louvres gives a clean, modern look in the ceiling.

• Size: 450 x 450mm
• Air pattern: 4-way
• Supply air only
• Finish: matt with high gloss louvres
• Clip-in modules
• Range: direct vent
• Type: multi directional diffuser (MDO)
• Code: SR45

As a multi directional diffuser (MDO), it sends air out through four sides of the face, and the face is built from clip-in modules. The diffuser is fitted to the end of a supply duct through an adaptor above the ceiling, then the face is set into position. Set it so the four discharge sides suit the room shape and keep the airflow off seating areas.

As it is listed for supply air only, plan a separate grille for any air intake in the same room. Check the ceiling opening, the duct size that will feed the 450 x 450mm outlet and the adaptor you will use before ordering, and confirm the matt and gloss finish suits the other outlets in the house.
