A-404 Pulse Vac Industrial Dust Collector

The A-404 Pulse Vac is a heavy-duty dust collector built for contractors who need strong suction, cleaner air, and dependable performance on demanding concrete jobs. It delivers continuous dust control for surface prep equipment, grinders, and saws.

Key Benefits

• Strong suction keeps dust off the floor and out of the air, improving visibility and workflow.
• Built-in pulse filter cleaning keeps the machine running without constant shutdowns.
• Large-capacity drum reduces the number of bag changes on bigger jobs.
• Durable frame and components built to handle daily use in tough environments.
• Easy transport with integrated handles and wheels, even when the drum is full.

Detailed Description / Features

The A-404 Pulse Vac is designed for contractors who need reliable dust collection while running grinders, shot blasters, scarifiers, and other surface prep tools. The heart of the system is its pulse-cleaning technology, which blasts air through the filters to keep them clear without stopping production.

A large 30-gallon collection drum gives crews longer runtime between disposal stops. The heavy-duty steel frame and commercial-grade components hold up to harsh jobsite conditions. High airflow and strong suction help remove fine concrete dust before it becomes airborne, keeping the workspace cleaner and safer.

The vac’s oversized wheels and balanced frame make it easy to move in and out of trailers, across slabs, and through tight commercial remodel spaces. Routine maintenance is simple, and the pulse-cleaning system helps extend filter life.
