3 Description The ceiling swirl diffuser type DQJA-SR / DQJA-SQ / DQJB / DQJR is particularly suitable for installation in comfort rooms with high air change rates. Unlike the conventional swirl diffusers, the air deflection blades can also be adjusted at a later stage. This may become necessary if there are obstacles in the air jet path. The diagrams clearly show the influence the blade position has on the radial propagation of the jet. The blades can be adjusted to achieve throw patterns from horizontal to vertical. This can be important, for example, if the air jet is to be directed toward a specific point where high heat loads are present. In difficult cases, the position of the blades can be determined by carrying out flow tests at the SCHAKO laboratory. Various air jet guide postions can be manufacturer preset. Air throw "B" is set in the factory unless specified otherwise in the order. The air diffuser is particularly suitable for installations with variable volumetric flow. A stable jet pattern is guaranteed by the high exit velocity. Even at a low volumetric flow the jet does not sink abruptly from the ceiling. If the "critical throw" x kr (m) parameter is smaller than the "horizontal throw" x (m) parameter for your model, then the calculation for the maximum end velocity of jet V max (m/s) is based on the "critical throw" x kr and not on the "horizontal throw" x (m) parameter. A plenum box with fixing lugs can be fitted to the ceiling swirl diffuser (-SAK for DQJA-SR... / DQJA-SQ / DQJB, SRK for DQJR-SR-...). The supply air diffuser model has two straightening grids, for return air the model is painted inside to RAL 9005 (black) as standard. In addition, the plenum box can be fitted (at an extra charge) with various components such as throttle damper (-DK), volumetric flow meter (-VME), ROB version(-rob) and rubber lip seal (-GD). The throttle damper (-DK) at the connection piece is for air volume regulation and adjustable from below (only DQJA-SR / DQJA-SQ / DQJB). For plenum boxes SAK, the damper (-DK) can be mounted on the room side with mounted diffuser. For plenum boxes SRK, the ceiling diffuser must be removed, before the damper can adjusted. Alternatively, a cable-operated adjustment (-SZV) can be attached, which allows the damper (-DK) to be adjusted on the room side even with mounted diffuser. In the connection piece of the plenum box, a volumetric flow meter (-VME) can be integrated. The measurement error of the volumetric flow meter is ± 5 % at a connecting piece velocity of 2-5 m/s and a straight flow pattern of at least 1 x D. The measurement is carried out with integrated diffuser. By adjusting the throttle damper, the required air volume of each diffuser can be set quickly and correctly. To allow duct cleaning robots to be inserted from the room side, the distribution sheet in the ROB version (-ROB) can be removed as well as the damper and the volumetric flow meter (if integrated). Other accessories (at an extra charge) are hit-and-miss damper (-SS-K, only for DQJA-SR / DQJA-SR-PS-Z / DQJA-SQ) for air volume regulation, ball impact guard (-BS, only for DQJA-SR / DQJA-SR-PS-Z / DQJA-SQ / DQJB), motor adjustment (-MV only for DQJA-SR / DQJA-SR-PS-Z sizes , activated via AGV-3), 1/4 cover (-AD, only for supply air version) and adjustable damper (-DV, only for DQJR-SR / DQJR-SR-PS-Z). TÜV SÜD has successfully inspected the ceiling swirl diffuser DQJ according to the following rules: - VDI 6022, Sheet 1: Hygienic requirements of ventilation and air-conditioning systems - VDI 6022, Sheet 2: Hygienic requirements of ventilation and air-conditioning systems - Measurement methods and investigations during hygienic controls and hygienic inspections. - DIN 1946, Sheet 2: Air-conditioning technology - Health requirements For mounting in the ceiling, inspection openings for the electrical connection must be provided on-site in sufficient number and size. Advantages - A subsequent adjustment of the blades on-site in the built-in state is also possible. - Noise level and pressure loss remain constant in all blade positions. - High induction ensures very good reduction of the velocity and the temperature difference. - Stable air jet even at reduced air volumes - Volumetric flow meter 05/01-3
4 Blade adjustments Pages 5-8 in the catalogue clearly show the extreme adjustment flexibility of the DQJA-SR / SQ ceiling swirl diffusers. It may become necessary to adjust the position of the blades if, after installation, there are obstacles too close to the diffuser obstructing the air flow, for example columns or cupboards. The "two-way throw" version is ideal for corridors. This avoids any deflection from the wall down to the occupied zones. The diffuser is preset by the manufacturer to air throw "B" as a standard feature unless specified otherwise when ordering. For size 310, the only air throw available is "A". The air throw patterns can be easily changed at a later stage on-site, even with the diffuser installed, without using any special tools. The pressure loss and the noise level remain constant in all blade positions.

9 Special model If, for constructional reasons (e.g. ceiling grid), a particular faceplate size has been defined, it is possible to punch smaller swirl diffusers (1) into the faceplate. If a plenum box is required, it will be delivered, as a standard feature, in the size as the punch and not in the size of the faceplate. However, if the plenum box is larger, the standard hole (2) in the blade is placed in the faceplate, to allow damper adjustment. In case of a screw mounting, the screw holes (3) are adjusted to the plenum box.

44 Specification texts Ceiling swirl diffuser type DQJA-SR-Z, with square faceplate, circular blade patern. Particularly suitable for installation in comfort rooms with high air change rates, for clean rooms (in connection with particle filter boxes) and for VAV systems with variable volumetric flows (between 40 and 100%). Cooling and heating modes are possible. With faceplate made of sheet steel with high-quality powder coating, painted sheet steel RAL 9010 (white). With central pivoting, aerodynamic radially arranged air deflection blades in support blade profile sections made of plastic RAL 9010 (white), RAL 9005 (black, standard) or aluminium painted in the RAL colour of the faceplate (blades are not adjustable subsequently). Each blade is adjustable from the diffuser faceplate without using any special device, without dismounting the diffuser. The blades are divided lengthwise, allowing an air throw with an even higher induction to be set (air throw "B"). Free cross-section, resistance and sound power level remain the same in all blade positions. With visible screw mounting (-SM). For size 800 with concealed mounting (-VM), with motor adjustment only possible with SM mounting.
