Dirtbag™ – Vacuum Pre-Filter

Protect your commercial vacuum motors and maximize suction efficiency with the AVW Dirtbag vacuum pre-filter. Designed as a direct breakthrough for car wash vacuum maintenance, this heavy-duty separator bag prevents fine dust, debris, and abrasive particles from ever reaching your primary filter canisters and vacuum motor housings.

By trapping contaminants at the entry point, the Dirtbag dramatically multiplies the operational lifespan of both your filters and motors. It ensures consistent, high-powered vacuum suction across all client drop-off stations, eliminating performance drops during peak operating hours.

Non-Stick Filtration & Maintenance-Free Performance

Built with an advanced non-stick fabric, the Dirtbag forces dirt and debris to slide off immediately rather than caking onto internal surfaces. This self-shedding design effectively stops filter clogging in its tracks, protecting central vacuum primary canisters from severe restriction.

By streamlining waste collection and reducing manual filter cleanouts, this system cuts routine vacuum maintenance time in half. Whether retrofitted into existing motor canisters or integrated into modern central vacuum layouts, it delivers reliable, low-maintenance protection that reduces equipment downtime and lowers operational replacement costs.
