The blast cabinet has a working area of 28" x 40" and contains tiny glass bead media in the bottom section. There is a large wire mesh that divides the upper and lower sections of the cabinet. The foot pedal is connected to compressed air and controls the flow of air going to the nozzle assembly. The air passing through the nozzle creates a vacuum and draws the glass beads from the bottom of the machine up into the air stream in the nozzle.  The machine requires 80-125 psi shop air. Glass beads are rapidly accelerated into the part you are bead blasting. The beads fall back into the bottom of the cabinet and are recycled through the system.

Operating the blast cabinet requires you to have a basic understanding of how the machine works.  Our machine uses glass beads, but can handle using other media. Many different types of media are used in industry including but not limited to glass, sand, walnut shells, and soda. Sand is one of the more aggressive media materials and works good on heavy rust.  When the machine foot pedal is pressed the air passing through the nozzle creates a vacuum and draws the glass beads from the bottom of the machine up into the air stream in the nozzle. It is very important not to step on the pedal when the cabinet door is open. The door prevents media dust from flying out into the room. It's also very important to only point the nozzle away from the glass and gloves.  The nozzle will destroy the glass window protector as well as put holes in the gloves if careless. Always make sure that materials are free from heavy grease and dirt before trying to blast them. There is a vacuum system with a filter attached to the side of the cabinet. This system pulls a vacuum on the cabinet and helps filter the dust created.
