Ceiling swirl diffusers

The database contains 17 articles relating to this field: "Ceiling swirl diffusers".
Please select from the following popup menu.

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 Dt = -14 K. Mounting height from 2.6 - 4 m, with motorised adjustable throw pattern of up to 6 m.

Volumetric flow range:
150 – 3,000 m³/h, use in VAV installations from 100 - 40%.

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. This allows the air to be blown into the room free from draughts even under extreme conditions (very high air change and high Dt). The air jet direction can also be adjusted later, either manually or motor-driven, 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 throw pattern is adjusted.

Models:
DQJA-SR - with square face plate, radial louvre pattern, standard screw mounting (-SM)
DQJA-SR-PS-Z - same as DQJA-SR, but with continuous through louvres (for supply air only), standard screw mounting (-SM).
DQJA-SQ -with square face plate, square louvre pattern, standard screw mounting (SM)
DQJR-SR - with round face plate, radial louvre pattern, standard concealed mounting (VM)
DQJR-SR-PS-Z - same as DQJR-SR, but with continuous through louvres (for supply air only), standard concealed mounting (VM)
DQJB-T70/T150 - with square face plate, offset by 70 / 150 mm, radial louvre pattern, standard screw mounting (SM)
DQJ...-...-Z - for supply air, with air deflection blades
DQJ...-...-A - for return air, without air deflection blades
Sheet steel front plate painted to RAL 9010 (white), stainless steel (V2A) painted in the colour sand silver or aluminium natural colour anodised
Plastic louvres RAL 9005 (black), RAL 9010 (white) or aluminium painted in the colour of the diffuser (louvres cannot be adjusted subsequently).
