� Swirl diffuser OD-9
• Square or round front mask• Square or radial deflector arrangement• Plastic deflectors• Possible volume control damper in
spigot• Foam sealing on the flange
Fastening of the plate
Fastening with four screw is recommended by sizes 600 and 625. For size 800, fastening with five screws is always applied (4xM4 + 1xM6).
