Ceiling Swirl Diffuser DQJA/DQJR

Fields of application

Supply air and return air installations in amenity rooms such as offices, shopping centres, restaurants, cinemas or clean rooms. They can be used for heating and cooling up to a Δt = -14 K. Mounting height from 2.6 – 4 m.

Function

The high induction of the swirl jet produced by the louvre layout reduces the end velocity of jet and the temperature difference very quickly. The air jet direction can also be adjusted later manually from horizontal to vertical. The free cross-section is the same in all louvre positions, so that pressure loss and volume level do not change when the air jet direction is adjusted.

Volumetric flow range

40 – 250 m³/h, use in VAV installations from 100 - 40%.
