New Vacu-Blast Walk-In Airblast System Offers Superior Environment for Controlled Processing

Ontario, CANADA - (October 30, 2002) - Ideal for applications ranging from precision finishing of delicate surfaces to removal of difficult rust and heat treat scale, the new Vacu-Blast® walk-in airblast room system offers a superior controlled processing environment for surface preparation. Designed for use with any type of abrasive blasting material including metallic (ferrous and non-ferrous) or non-metallic, the Vacu-Blast system features high quality ventilation and lighting provisions, superior dust collection, as well as a choice of two different media recovery systems: Vacu-Draft(TM) pneumatic or mechanical.

Superior USF Surface Preparation Group filtration technology meets even the strictest environmental control requirements. Offering high collection efficiency, low cost operation, and
a compact design, dust collectors are constructed with all welded 12-gauge steel for housing and hopper and are equipped with pleated paper-type filter cartridges designed for airblast
applications. A distinctive cylindrical cartridge captures contaminants on the outer filter media surface, while cleaned air passes through the cartridge and out the exhaust fan outlet.
Vertically hung cartridges allow maximum cleaning during the pulse purge cycles and are easily replaced through an external mechanism. Standard equipment includes a magnahelic gauge
mounted on the collector support leg, a manual slide gate for the hopper discharge, and a butterfly air-balancing gate on the dust collector air inlet(s).

Ideally suited to handle a variety of medium to lightweight abrasives including aluminum oxide, gamet, and glass beads the self-supporting Vacu-Draft recovery system is formed from 16-gauge steel and offers a grid-type floor that eliminates the need for deep pits. Trough and shed plate construction includes valley angles greater than 45 degrees for improved media flow. A uniform flow of ventilating air constantly moves media from the room enclosure through the grid floor and into the recovery ducts. Bolted in place, each floor hopper section can be replaced individually. The Vacu-Draf(TM) pneumatic system is durable, easy to assemble and fully supported by the USF Surface Preparation Group distribution network, reducing customer costs to install and maintain the system.

The mechanical recovery system and its long-life bearings also provide customers proven performance and durability. Combining downdraft and end-to-end airflow designs, the mechanical recovery system incorporates a conventional bucket elevator and airwash separator with rotary scalping screen. Constructed of 14-gauge galvanized wall and room panels with an 8' x 8' solid core work door and dual latch point door closures, the mechanical recovery system is ideal for heavier media applications such as steel shot and grit. Six-inch diameter augers with proven hollow core bearings maintain a gap under the segments; providing a bed of abrasive to protect the hoppers from the moving abrasive.

Each blast and recovery system is designed and supplied with a factory installed relay logic system that is UL and CSA approved. An interlocked limit switch with control panel
ensures optimum safety during blasting operation. When chosen or required, a breathing (free) electric air pump, complete with inlet filter, provides clean breathing air for the operator. A 6.5 cubic foot Schmid(TM) pressure blast tank comes complete with MicroValve control, ComboValve(TM) control, 1 ½ inch tank piping and a NIOSH approved blast helmet with cape.

Through the USF Surface Preparation Group's Distribution organization, Vacu-Blast customers can access a wide range of support services including site visits and consultations by
experienced service or process engineers, machine and system performance checks with written documentation, maintenance and updating of machine systems, inventory of high wear
service parts, and more.
