Ceiling impulse diffuser PIL

Fields of application

Supply air and return air installations in amenity rooms such as offices, shopping centres, restaurants, cinemas or clean rooms. They can be used for heating and cooling up to a Δt = -15 K. Mounting height from 2.6 – 4 m.


The ceiling impulse diffuser produces a pulsating jet of air which penetrates the room horizontally. This pulsation has the effect that the end velocity of jet and the temperature difference in the supply air are efficiently reduced, despite the low induction.

Volumetric flow range

90 – 1,500 m³/h, use in VAV installations from 100 - 40%.
