Dust Collector Sizing Calculator

Sizing a dust collector correctly is critical for safety, visibility, and compliance in blasting and painting operations. This calculator makes the process simple by letting you enter details about your job site or facility—such as the number of operators, enclosure dimensions, airflow targets, and environmental conditions—and instantly see the recommended CFM, face velocity, and air changes per hour. It also highlights compliance cues based on OSHA and NFPA standards, giving contractors, engineers, and safety professionals a quick, reliable way to estimate ventilation needs for both portable job sites and fixed blast or paint booths.
