    摘要： The invention is a filter group (1) comprising a filtration region (R) extending between an inlet area (IN) through which fluid to be filtered flows, and an outlet area (OUT) through which filtered fluid flows. The filter group (1) extends along a longitudinal axis (X-X), along a transverse axis (Y-Y) and, in height, along a vertical axis (V-V). Furthermore, the filter group (1) comprises: a filtering panel (3) extending with respect to an imaginary plane (F) and which may be crossed by the filtration fluid in a direction substantially orthogonal to the imaginary plane (F); —a baffle panel (4) impermeable to fluid; —an inlet chamber (5) defined between the filtering panel (3) and the baffle panel (4), wherein the inlet chamber (5) is open in a proximal region to the inlet area (IN) and is closed in a region which is proximal to the outlet area (OUT).

    摘要： A filter arrangement for filtering dust-laden air generated by a hand-guided power tool having a motor features a filter cartridge having a hollow casing with a longitudinal extension along a longitudinal axis, a hollow filter element located inside the hollow casing, having a longitudinal extension along the longitudinal axis, an air inlet port in the hollow casing, pneumatically connected to the power tool to allow the dust-laden air generated by the power tool to flow into the hollow casing, and an air outlet port in the hollow casing, to allow filtered air to leave the filter cartridge. An external chamber of the filter cartridge is formed between the hollow casing and the hollow filter element. An internal chamber is formed inside the hollow filter element. The internal chamber is closed by a conical head portion at a first end of the internal chamber facing towards the air inlet port. The external chamber is in pneumatic connection with the air inlet port and the internal chamber at a second end opposite to the first end is in pneumatic connection with the air outlet port. The filter arrangement includes an active airflow generating device being in pneumatic connection with the air outlet port and the internal chamber of the filter cartridge in order to generate or support the airflow through the filter cartridge.
