Construction · Dimensions · Materials Construction The face sections of the type DLQ and ADLQ consist of a peripheral border with fixed air control blades. The plenum box is supplied with a circular side entry spigot and an optional volume control damper which can be adjusted from the front face. The diffuser face is permanently rivetted to the plenum box. The diffuser face is made from formed sheet steel. The surface is pre-treated and powder coated white (RAL 9010). The plenum box is made from galvanised sheet steel. ADLQ Materials The diffuser face is made from extruded aluminium sections,...

Discharge Directions Location of Connecting Spigot The diffuser face can be supplied in a 1 to 4 way discharge pattern, as required. The side entry spigot of the plenum box is located on side A as standard. If the customer requires it to be located on another side for architectural reasons, this must be indicated in the order code. (No indication need be given for the 4 way discharge pattern).
