Salient Charicteristics:

The main blast chamber is a closed steel frame approximately 60in x 50in x 40in where workers can place parts that they are working on. The front has two holes where blast safe gloves are attached so the worker can safely control the blast nozzle. A screen(glass) is above the gloves for viewing the inside of the chamber. The blasting hose and nozzle come down from the top of the unit. The top also has an intake, with filter that draws in air while stopping particles from escaping the chamber. Inside the chamber there is a grated shelf where parts are placed but media is allowed to fall into the reclamation area. The bottom of the blasting chamber is conical and a 3-5 in hose attaches to vacuum to dust collection and the filters system.

Used media goes through a centripetal force separation where the usable media is separated from the waste media. Good media is cycled back into a hopper for use. Waste media goes through a filter system and directed into a 55 gallon drum. Dirty air passes through the pre-HEPA and HEPA filters and exhausted into the building as clean air. The HEPA filters are usually 99.97% efficient to 0.03 microns. Air handler takes building service air usually between 150-175 PSI and allows the user to control the airflow to the nozzle by use of a foot pedal. The air flow activated a hopper directing media into the airstream and controls on the blast chamber allow the adjustment of nozzle pressure and media flow rate.
