Blastmaster® 20 Cu. Ft. Abrasive Blasting Pots
The Blastmaster® 20 Cu. Ft. Abrasive Blasting Pots are pressure vessels used as part of an abrasive blasting system to deliver a mixture of abrasive and compressed air to a work surface. Marco blast pots are proudly engineered and manufactured in the USA and built in accordance with ASME guidelines. Each Marco blast pot is designed with added features to enhance work site safety. Blastmaster® Abrasive Blasting Pots are manufactured using higher quality materials that resist wear, reducing costly downtime and increasing production rates. Typical applications include blast rooms, blast yards, bridges, oil refineries, pipelines, railcar shops, storage tanks, and water towers. Common abrasives used include aluminum oxide, crushed glass, garnet, mineral abrasives, slags, and steel shot and grit.

Enhanced Safety

OSHA requires an abrasive blasting pot to be equipped with a remote control system, which only operates with continuous hand pressure and deactivates upon release of the control switch by the operator (29 CFR 1910.244(b)). This remote control system meets the OSHA requirement by providing a “Fail-to-Safe” configuration, which will deactivate the remote control system in the event the operator drops or loses control of the remote control switch.


The capacity of the Blastmaster® 20 Cu. Ft. Abrasive Blasting Pot is able to hold up to 20 cubic feet of abrasive, increasing production by extending blasting time between each fill.


Our commitment to producing the highest quality products in the industry demands strict control over our raw materials and manufacturing processes. All components used in the manufacturing of Marco products adhere to strict process controls as specified by Marco’s Quality and Engineering team.
