Ceiling Impulse Diffuser Model PIL Description connected to ductwork via a reduction piece type RF. The ceiling impulse diffuser type PIL-... has been specially designed for use in clean rooms, operating theatres and comfort rooms up to heights of 4m. It produces a pulsating horizontal jet stream. The supply air is discharged along the ceiling and, upon reaching the critical throw length, gradually sinks into the occupied zone at low velocity. The pulsating air pattern results in an efficient reduction of the velocity and of the temperature difference in the air jet. A displacement flow is created...
