Material used
The diffuser can be supplied with a round or square front
plate manufactured from galvanized steel. The surface is
powder painted white RAL9010 as standard, or another
RAL code can be specied. It is also possible
to manufacture a stainless steel AISI304 or AISI316
version, without surface nish.
The deectors are made from plastic, available in black
or white colour. In the middle of the diffuser there is
a pre-punched hole for front plate screw xing. A screw
with a white decorative cap for its installation is provided
together with a self-adhesive seal, which must be
adhered at the installation site.
