AREAS OF APPLICATION

The wall duct is for fresh and outgoing air flow through solid or system walls and ceilings.

Almost any duct thickness is feasible because of its modular construction and the variability

allowed in the module insertion depth.

The modules are connected during assembly using a suitable adhesive.

FLANGE REDUCTION SLEEVE

The flange reduction sleeve is for connecting to air pipes in the inside of the building.

i

Drill holes for wall mounting with screws

i

Condensation drain

The connecting pieces can be connected via a tube to a drain.

If this is not required, a plug is used.

i

Surrounding groove for accommodating insulation in the connecting pipe (minimization of thermal bridging)

CONNECTION SLEEVE WITH COLLAR

The connector sleeve serves to connect the sleeve with the flange reduction sleeve.

WEATHER PROTECTION GRILL

The weather protection grill guarantees a minimal loss in pressure due to the large free areas and fluid streamlined rib design.

Supporting edge and spigot length are generously sized for sufficient coverage of the plaster surface and the insertion depth
