ABSTRACT:
A filter for filtration of fluids includes a filter cloth arranged in a housing with an inlet and an outlet. An acoustic field produced by an acoustic transducer, can act on the filter cloth. The invention the filter cloth is arranged substantially in a pressure node, i.e. a velocity antinode, of the acoustic field. As a result, a relatively inexpensive filter is obtained which is economical to operate due to the long durability of the filter.
