Compatibility:
Outlets - it is fully compatible with LUFTOMET® Sky, Jet, and Lumen outlets with a diameter of 125 mm. In this combination, the outlet’s neck is directly anchored into the collar of the LUFTOMET® Round Box Low without the need for plugs.
Ducting - the neck of the box is designed to accommodate flexible plastic ducts with an outer diameter of 75 mm and 90 mm, such as Dalflex, ComfoTube, ED-FLEX, ROZ-DUOTEC, Ubbink Air Excellent, Klimaflex, Octopus AE48c, HEATPEX Aria, Kermi x-well, FLXP, Atera GreenPipe, Lindab Indom, etc.
Installation Procedure:
Rough Construction
-
Cut the duct to the appropriate length (preferably using the LUFTooL Duct Cutter) and secure it approximately 1 meter from the planned outlet position.
-
A sealing ring is placed into the second groove of the duct.
-
Slide the duct into the neck of the box.
-
Insert the spike into the prepared hole in the body of the box so that it fits between the ribs of the duct.

The duct can be rotated but cannot be pulled out. Sealing is guaranteed by the O-ring.
- The box is capped with a 125 mm lid for securing.
After Installing Drywall and Painting
-
Place the box into the cut-out hole so that its outer collar rests against the upper edge of the drywall. The duct must not exert pressure on the box or the drywall.
-
Insert the neck supplied with the outlet into the box. The collar of the neck is secured with screws through the drywall into the collar of the box.
-
The design plate of the outlet can be easily attached to the neck using magnets (for the LUFTOMET® Sky, Jet, and Lumen outlets).
