摘要

The coating powder filter (6-8) has a filter surface for filtering through a coating powder sand an ultrasonic source for stimulating vibrations of the filter surface. The filter surface is angular, e.g. rectangular with sides of different lengths, and is inclined to the horizontal so that dirt particles that have been filtered out pass off to the side.
