Levelling
The OXYFLEX
®
- MF1100 membrane plate diffuser is mounted onto distribution pipes (round or square pipe
depending on version). The distribution pipes must be levelled to a maximum of ± 10 mm.
For installation on round pipes with Supratec supporters,
the pipe clamps must be tightened with torque of 10 Nm
(M10); 20 Nm (M12). The surface pressure that this
produces ensures that installation is distortion-free.
Threads have to be lubricated before screwing the nuts to
avoid seizing.
Type 'B': Installation on square pipe
The OXYFLEX
®
- MF1100 type 'B' membrane plate diffuser is mounted on a square pipe (width at least 60 mm)
with 4 threaded bolts M6 x 35 mm.
An EPDM gasket is inserted between the diffuser and the distribution pipe. The surfaces must be clean and
straight. Gasket must sit clean and undamaged between the diffuser and the pipe.
The distance between the bolts is 227 x 30 mm (see sketch). We would be pleased to provide you with an
appropriate welding template. The air-socket Ø = 29 mm is inserted from above into the bore hole Ø = 30 mm of
the square pipe and bolted in place using the threaded bolt that is now protruding from the side fastening lug of the
diffuser frame with washers and self-locking nuts M6 (4 Nm). The threaded bolts must be lubricated beforehand to
avoid seizing.
Always make sure that the diffuser is firmly and horizontally seated.
