Step Impulse Diffuser SIA

Fields of application

Supply air installations with step-mounted ventilation in pressure floors for the air-conditioning of festival halls, auditoria, theatres and cinemas.


Inductive step-impulse diffuser with high-speed reduction in temperature and speed after only a few centimetres. Suitable for heating and cooling at a maximum ΔT of +/-6 K.
Ingenious fittings on the inside of the SIA reduce the speed and temperature at a distance of only 0.4 m between diffuser and legs at such a high rate that no draught is formed, this being achieved even at a maximum temperature difference of -6 Kelvin.
The diffusers are connected via pressure floors.
