Nozzle jet diffusers
Airports, pools, sports facilities, shopping malls, theatres, atriums: when air has to cross a large room, a nozzle throws it where ceiling diffusers cannot reach. EffectiV jet diffusers do it with a presence architects are willing to show.
The throw
Nozzles concentrate the air into a jet that keeps its velocity over long distances, without relying on the Coandă effect of a ceiling. On a KOO panel every nozzle is aimed by hand: straight, the nozzles throw jets that surpass 100 ft; angled, they widen the pattern and shorten the throw to cover an area rather than a point.
Maximum throw
Parallel jets that keep their velocity to the far end of the room. To reach a distant zone, or to wash a curtain wall from the opposite wall.
The models
01 KAM-W
An adjustable nozzle with hidden screws, for a wall or a ceiling. Its aluminium construction makes it the choice for pools and aquatic centres. Manual, actuator-controlled (KAM-W-M5) or thermodynamic (KAM-W-ACTIF).
02 KAM-D
The same nozzle without the flange: it inserts directly into the opening of a round duct. The nozzle of open ceilings with exposed ductwork. Manual, actuator-controlled or KAM-D-ACTIF.
03 KOO
One or two rows of 2 to 10 nozzles in a rectangular panel, two nozzle diameters, 32 sizes, 15 to 1065 cfm per diffuser. Every nozzle is aimed by hand: long throw or wide spread.
04 KOBE
A continuous long-throw slot in six widths. On the wall to cross a large room, in the ceiling to push air down along a glazed wall. Jet adjustable by ±30°.
Three ways to adjust
01
The base model: the jet angle is set by hand at installation or balancing.
02
KAM-W-M5 and KAM-D-M5 take an actuator so the jet angle can be driven from the control system.
03
KAM-W-ACTIF and KAM-D-ACTIF tilt their own jet 30° down in heating and 30° up in cooling. No power, no controls.
Thermodynamic diffusersApplications
KOO
To treat a large glazed wall, the reflex is to run ductwork to the top of the window and create an air curtain. A KOO panel on the opposite wall washes the same glass from a distance: often less duct, less labour, and real energy savings when the window is tall.
