Ceiling Diffusers Type DQ · Type ADQ recommended for room heights from 2.60 m to 4.00 m TROX GmbH Heinrich-Trox-Platz D-47504 Neukirchen-Vluyn

Contents · Description Description Construction · Dimensions Materials Installation Directions of Discharge Nomenclature Technical Data Aerodynamic Data Order Details Square or rectangular construction ceiling diffusers, either in aluminium (type ADQ) or steel (type DQ). Ideal for horizontal air discharge in a flat ceiling. The directions of discharge can be selected to meet the requirements of room geometry, with 1 to 4 ways available. These ceiling diffusers are suitable for both supply and extract air application.

Construction · Dimensions · Materials · Installation Construction The type DQ and ADQ diffuser faces consist of a border with counterpunched holes and fixed blades for horizontal discharge. Available with 1 to 4 ways discharge face. Additional rear mounted opposed blade damper, operable from the front face is also available. The diffuser face is in extruded aluminium sections natural anodised E6-C-0. The rear ancillaries are in formed sheet steel. The surfaces are phosphate treated and black stove-enamelled (RAL 9005). The installation subframe is rolled galvanised sheet steel. The diffuser face...
