Air Diffuser INDUDRALL

Highly inductive ceiling air diffuser in various designs, shapes and colours. Special designs leave plenty of room for individual room-specific design wishes.

The strengths of INDUDRALL


Low pressure losses and high temperature differences are the prerequisite for energy-efficient operation throughout the air-conditioning plant.


Very distinctive ceiling air diffusers that are often used as an aesthetic design element of ceiling architecture.


Kiefer air guide elements are optimised in terms of flow technology, enabling draught-free introduction of air even in demanding conditions.


The discharge flow from the front panel of INDUDRALL is fan-shaped. The respective blocks composed of single elements form jets in order to optimally induce the ambient air. Very soon after leaving the diffuser the temperature differences have largely dissipated. A highly turbulent ambient air flow is formed, which represents the optimum in terms of low ambient air velocities and temperature differences. The air duct elements offer scope for a wide variety of solutions that are optimally adapted to the individual room situation. The individual elements can also be adjusted or replaced after installation if room situations change over time.
