That answer lead us to further define that machine as having:

1. Easy operation and maintenance for painters not trained as mechanics
2. Very clean grit (under 500 PPM) to get the full benefits of recycled steel grit (no dust)
3. Low restriction, low maintenance vacuum system to maximize vacuum speed (tonnage per hour) and reduce fuel consumption
4. Ultra compact design to allow use of I-R HP1300 (or other compressor) on front of trailers
5. Universal design of modules allows them to be used to update all makes of competitive machines

• The fewest moving parts with NO double dump valves, bucket elevators, conveyors, augers, gearboxes, chains or belts to wear and breakdown
• Gravity recovery directly into the VPC with 5 minutes setup. No vacuuming required.
• Watertight design without using full van enclosure which makes it easy to access all parts of the machine
• Easy interchangability of various modules to allow upsizing and downsizing.
• 24 volt DC power (diesel engine battery) to run control systems eliminating the chance of electrocution or grounding problems. 110 volt AC power required for demag system.
• Pneumatic movement of grit between modules using very little CFM of air.
• Rugged and reliable PLC control system to replace sensitive relays and timers
• Automatic and manual control of all functions simplifies operation and maintenance
• High fuel efficiency for vacuuming and grit recycling
• Grit recycling system is usable with all makes of vacuums
• 8’-0" high modules and 9’-6" high modules, both 8’ to 8’-6" wide

• Lack of dust makes it possible for blasters to see EXACTLY what they are blasting
• With low restriction vacuum, vacuuming is accomplished faster and at a lower cost
• Easy automatic and manual operation with full system flow diagram and pilot lights
• Low operation and maintenance costs
• Easy operation makes it possible to get more square feet cleaned in one day and grit recycled for the next days operation
• Lack of moving parts dramatically reduces chance of downtime and greatly simplifies daily maintenance
• Ultra compact design makes it possible to have a fully self-contained trailer requiring little setup on the job. This is perfect for lane closure work with tight time schedules
