Swirl Diffusers | 2 / 5
Design
The diffuser is manufactured with a square front panel
made of galvanized steel. The surface is powder-painted
with a signal white RAL9003 by default, other RAL types
can be applied upon request. In the diffuser’s center
there is an opening for mounting the diffuser front panel
using a screw. Every VVT front panel includes a screw
with a decorative white cap for its mounting onto a
plenum box as well as a self-adhering seal, which needs
to be placed onto the diffuser front panel during the
installation.
