Abstract (en)
[origin: EP0497296A2] The filter/ventilator arrangement is used in clean rooms and has a ventilator (9), the pressure side of which faces an airflow space (21, 23). It is formed by an annular duct, at least one of the delimiting walls (13a to 13d, 20a to 20d, 22a to 22d) of which consists of sound-absorbing material. The arrangement is of compact design. The annular duct (21, 23) makes possible uniform flow distribution and uniform speed across the surface of the downstream filter, so that the air can penetrate uniformly through the filter into the clean room situated below. The annular duct (21, 23) makes possible very short flow paths, as a result of which there are low flow losses and a low energy requirement. <IMAGE>
