Construction RFD-Q
The application of TROX swirl diffusers has been extended
from the comfort conditioning field and has found a
significant number of industrial applications. Therefore, to
complete the range of FD swirl diffusers which have been so
successful, the RFD range has been extended to include
smaller diameters.
The construction of the diffuser results in a swirling rotational
type of discharge of supply air ensuring a high level of
induction and rapid reduction in temperature differential. The
noise levels are low.
Swirl diffusers can be used in either constant or variable air
volume systems with excellent performance characteristics
when air flow reduces from 100 % to 25 %.
Swirl diffusers type RFD can be installed in many situations:
in continuous ceilings, suspended without a ceiling, above
open grid ceilings and in ceiling panels (max. 20 mm thick)
using fixing clamps. On request, the face shape of the
diffuser plate can be changed to meet specific architectural
requirements.
