INDULCLIP ceiling air diffuser

Excellent level of thermal comfort, a striking design and proven technology – the INDULCLIP has every angle covered. The large volume of ambient air induced means high cooling loads can be achieved for draught-free interiors. The air diffuser can be used universally to create a comfortable ambient climate in offices, retail properties and hospitals, to name but a few examples.

INDULCLIP strengths


Low pressure drop and high temperature differentials are the prerequisites for energy efficient operation in the air conditioning system as a whole.


A range of different design options, shapes and colours allow plenty of scope for individual ideas and designs. Not all ceiling air diffusers have to be round or square!


Kiefer's flow-optimised air guide elements enable draught-free air induction, even under demanding conditions.


The clip elements specially developed by Kiefer enable high induction, so large differentials in temperature – down to -12 K between the supply air and ambient air – can be quickly balanced out, to achieve draught-free air distribution. The result is an energy efficient ventilation system with a high cooling capacity, as there is no need to heat the outdoor air following heat recovery in the central unit.

Sizes 300 mm - 800 mm
Designs Round and square
Supply air temperature difference Down to -12 K
Air flow rate 100 - 1500 m³/h
Room height 2.3 m to approx. 8 m
Front panel RAL colour of choice
Single elements Black or light grey (RAL 7035), other colours possible on request
Butterfly damper Adjustable from the room

Flow patterns

The individual air jets flowing through the air guide elements create a stable tangential flow pattern, flush with the ceiling. The air stream adheres to the ceiling due the Coanda effect. As a result, ambient air is induced, which produces the ideal balance of both air temperature and velocity.
