APL - Jet nozzle diffuser

Compact jet air supply for wall or ceiling installations
Ideal for large spaces and with adjustable throw pattern.
- Specially designed for large enclosures
- Long throw pattern with low velocity reduction
- Auto-balancing of the duct work due to units high pressure drop
- Directional air pattern; maximum deflection angle of 30° in all directions
- Circular duct connection with rubber gasket
- Corrosion resistant aluminium material
Product Models
- Model with adjustment damper
The supply air jet is directionnal in an angle of 30°, when the angle roll is 360°.
The jet diffuser ensures the auto-balancing of the network due to its high pressure drop.
The jet diffuser ensures a good diffusion for large enclosure.
The jet nozzle is made of heavy aluminium.
The colour of the jet diffuser is either anodised or white (RAL 9010).
The jet diffuser includes a sealing gasket.
Directional adjustment is accurate, accomplished without the use of special tools, and is able to provide 70° of global rotation with minimal restriction of movement.

APL without damper (standard) | APL/N |
The aluminium aperture damper is connected to the adjustment knob via a stainless steel connecting link, tension spring and hardware, providing corrosion resistance.
Function ▲
Supply air is supplied to the space at a high velocity.
The supply air mixes efficiently with the room air, with a high induction effect.
The supply air jet can be directed at an angle of 30° when the angle of roll is 360°.
Adjustment of the supply air pattern (Halton APL/A model) can be performed manually.
Installation ▲
Code description
1. Frame
2. Fixings screws
The Halton APL jet nozzle diffuser is fastened to the wall with screws.
Screw the fixing screws into the pre-drilled holes in the front panel.
Note :
When a connection to the duct is required, an additional part can be supplied (Flange for Halton APL).
Servicing ▲
Remove the diffuser by unscrewing the visible fixing screws.
Clean the parts by wiping them with a damp cloth.
Push the diffuser back into place and screw in the fixing screws.
