Suction system, has guide plate guiding suction volume flow to larger part corresponding to formation and direction of guide plate and further guiding flow to smaller part by through-flow openings radially to middle part of process unit

摘要

The system (1) has supports (4) extended in a middle region between a base (21) and a cover (22) of a process unit (2). Suction volume flow radially flows into the process unit in an inlet region. A guide plate (5) is formed at the inlet region, and guides the suction volume flow to a larger part corresponding to formation and direction of the guide plate and further guides the suction volume flow to a smaller part by through-flow openings radially to a middle part of the process unit. A filter (7) is arranged in the process unit and detached over complete volume flow from the process unit. The filter is formed as a lamella filter and a round filter.
