The fluid to be filtered enters through the top collar of the filter bag. As it passes through, particles are caught by the filter cloth while the clean fluid exits from the outside. Over time, trapped particles build up, increasing the pressure difference across the bag. This indicates that the filter bag needs to be replaced.
