Low-noise exhaust gas expulsion assembly

摘要

The exhaust air stream blowing arrangement (10a, 10b, 10c) has an air-permeable and noise-absorbing foam filter (12) in which the exhaust air flow (11) at the upstream side (13) coincides with a main flow direction in the foam filter. An impermeable baffle (15) arranged on a downstream side (14) of the foam filter deflects the air flow in the foam filter out of main flow direction. An independent claim is included for method for blowing exhaust air stream.
