li ndab | ceiling diffusers Plain diffuser CRL is a circular diffuser with an unperforated adjustable face plate. CRL can be used both for supply and exhaust air. The diffuser can be switched between horizontal and vertical supply air, and is therefore suitable for the horizontal supply of cooled air or vertical supply of heated air. Installing a CRL diffuser 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. It is also possible to install a damper directly in the diffuser to enable adjustment without a box. * ØU = Ceiling grid opening Dispersal patterns CRL is supplied with vertical supply air as standard. The dispersal pattern can be changed to horizontal supply air by moving the face plate. • Suitable for both supply and exhaust air • Suitable for horizontal or vertical supply air patterns • A damper can be installed on the diffuser to achieve adjustment The face plate can be removed to enable cleaning of internal parts or to gain access to the duct or plenum box. The visible parts off the diffuser can be wiped with a damp cloth.
