The Model 999 pressure-blast cabinet has a 48 in. x 48 in. x 144 in. (1220 x 1220 x 3660 mm) work envelope fitted with multiple blast nozzles, which can be used from each of the six operator workstations. The cabinet is equipped with a track extension and a transfer cart that moves in and out of the blast machine by means of a ball screw-ball nut mechanism driven by an electric gear motor. When the shuttle cart is fully outside the cabinet, there is easy access for loading heavy pipe components using forklift, hoist and overhead crane. Catch-hoppers under the track extension collect carry-out media and return it to the system's cyclone separator and reclaimer.
