Square ceiling diffusers type DLQ and ADLQ Varyset are ideal for use in variable volume systems (VAV systems).
Despite a large turn down in volume flow from 100 to 25% even when cooling, the diffuser maintains a stable horizontal discharge along a ceiling.
The automatic Varyset flap on the entry to the plenum box is self powered, i. e. no external power supply required.
Type DLQ and ADLQ Varyset ceiling diffusers are ideal for flush mounting in ceilings of room heights up to 4.00m.
