Circular cone ceiling or duct mounted
diffusers, are capable of a high aspiration
rate and have the capacity to handle
large volumes of air at relatively low
sound levels for supply and extract
applications, making these diffusers
particularly useful for installation in open
plan areas such as auditoriums, airport
lobbies, supermarkets and factories.
FKD is an adjustable circular multi-cone diffuser, which is typically used for supply air. The diffuser can be switched between horizontal and vertical supply air and is therefore ideal for the supply of both heated and cooled air. Installing an FKD diffuser up to size 400 in a plenum box type MBB can help to achieve a stable airflow to the diffuser as well as realise the potential for individual adjustment.
The multi-cone insert can be removed to enable cleaning of
internal parts or to gain access to the duct or box. The visible
parts of the diffuser can be wiped with a damp cloth
FKD is supplied for vertical supply air as standard.
The dispersal pattern can be altered to horizontal supply air
by setting the inner part of the diffuser to its lowest position.
