CONTENTS Adjustable blade variable geometry diffuser DVP 2 Quick selection table 4

Adjustable blade variable geometry diffuser DVP Description The adjustable blade variable geometry diffuser Model DVP provides an optimum discharge in cooling (horizontal discharge) and heating (vertical discharge) enabling the diffuser to meet the required comfort criteria .by moving its blades The diffuser is available in 9 sizes ranging from Ø160 mm to Ø 800 mm in manually version and 6 sizes from Ø250 mm to Ø630 mm either motorised or thermo-adjustable versions Operation The adjustable blade variable geometry diffuser allows the air discharge horizontal, inclined and vertical by moving its...

Dimesions The DVP-type diffusers have a variable geometry and were designed to meet the air conditioning needs of areas which, depending on the thermal loads during the various seasons of the year, require cold or hot isothermal air. By changing the positioning of its blades, the direction of the outlet airflow is changed, thereby achieving a horizontal or vertical throw, as well as adjustment within several intermediate positions. - The DVP-type diffuser was designed by the Research & Development Department of KOOLAIR, S.A., and tested and calibrated in our own Distribution and Acoustic Laboratory,...
