Bosch VAC090AH 9 Gallon Dust Extractor with Auto Filter for Grinder 1773AK

The Bosch VAC090AH is a 9 gallon dust extractor designed to handle job site dust collection during demanding tool operations. It solves the problem of rapid filter clogging and heavy airborne dust, making it a natural fit for tradespeople, contractors, and woodworkers who frequently run dust intensive tools like grinders.

High performance suction comes from a motor setup that generates up to 150 cubic feet per minute (CFM) of airflow and 97 inches of static water lift. To keep that airflow continuous, the unit features automatic filter cleaning that clears the filter every 15 seconds. This self cleaning cycle prevents fine powder from caking over the intake, so you spend less time stopping work to clear jams or tap out filters manually. Filtration relies on a HEPA filter that captures 99.97 percent of particles down to 0.3 microns, supported by an included fleece filter bag that securely holds dry dust while protecting the main filter element.

Everyday convenience relies on smart power tool integration. The tool activation feature lets you plug your tool into the vacuum so that switching your power tool on or off automatically starts and stops the extractor. A dedicated Power Broker dial allows you to match the exact suction strength to the task at hand, preventing lighter materials from sticking to the intake nozzle. Furthermore, the unit incorporates the Bosch Pro plus Guard system to help users work toward OSHA Silica Table 1 dust compliance.

Some clear trade-offs should be kept in mind based on the specs. The fleece filter bag is specified for containing dry dust and debris, meaning this vacuum is tailored primarily for dry extraction tasks rather than bulk liquid cleanup. Additionally, meeting OSHA dust standards requires pairing the unit with appropriate dust collection shrouds and accessories.

Verdict: The Bosch VAC090AH is an excellent investment for professionals who need high volume dry dust collection without constant maintenance breaks. Its automated filter cleaning and tool activated power control make it ideal for anyone running grinders or heavy dust machinery on the job site.
