ABS Filter Receivers eliminate the need for a cyclone filter at the pump because the air is filtered directly at the vacuum receiver. They are designed to optimize airflow through the unit and minimize restrictions. These units have a precise measure of delta P, which is used to alarm and control cleaning cycles so only dirty bags are cleaned. Front door allows easy bag access, and bags are connected with quick-release claps to make bag-changing a snap. Self-cleaning, completely sealed design purges waste into an easy-to-clean canister.
