Product Profile: Saving with a Blast Recovery System


By Chris McNamara, Rapid Prep, LLC

Designed for contained open or vacuum blasting, the Rapid Prep Vacuum Blast and Recovery Systems (VB) blast abrasive through two or three blasting outlets onto the surface being finished. The high-powered vacuum system recovers the spent abrasive where the dust and waste are separated. The used abrasive is recycled and returned to the storage hopper for re-use.

The VB systems allow for the use of any type of recyclable abrasive, including steel grit, aluminum oxide, garnet and others. Using steel grit, it is possible to get more than 200 recycles, greatly reducing abrasive and disposal costs.

Watch the systems in action:


VB 1200
• Two blasting outlets
• Blast pot capacity 16 cubic feet
• Storage hopper capacity 16 cubic feet
• Vacuum and classifier

VB 2400
• Three blasting outlets
• Blast pot capacity 35 cubic feet
• Storage hopper capacity 35 cubic feet
• Vacuum and classifier

According to Rapid Prep, these systems 1) provide maximum worker protection, 2) continuously recycle the abrasive, 3) separate the dust and 4) deliver high productivity — resulting in a safe and cost-effective decontamination and surface preparation. The VB systems are designed and built to be simple and affordable to operate, making them a smart entry-level option for contractors who are new to abrasive recycling.  

The VB 1200 and 2400 systems each have two high-powered jet vac pumps, capable of recovering abrasive over 200 feet away and at rates up to 9 tons per hour. Each vacuum pump consumes 275 cfm of compressed air and produces 700 cfm of vacuum power at up to 22 inches Hg, all with no moving parts, making the unit low-maintenance.

The VB systems include an air-wash and a vibratory screen classifier built into the abrasive storage hopper, so clean grit is stored right above the blast pot, ready for use. When the blast pot is depressurized, clean abrasive automatically flows into the pot. Rapid Prep blast pots are all rated for 150 psi working pressure, allowing for higher production and long blast hose runs. The blast pots can be equipped with several different types of abrasive metering valves based on customer preference.

The systems also include a self-cleaning, four-cartridge dust collector to filter the vacuum air and collect the dust being removed from the grit. This dust collector has vertical mounted filters and is cleaned using the reverse pulse jet method, blasting compressed air into the inside center of the filter so dust is released. Each filter has its own pulse valve for maximum cleaning.  

The entire system is mounted on a steel skid with fork pockets and lifting eyes along with a shipyard lifting frame, making the units easy to move and transport.

The VB 1200 and VB 2400 systems are currently being used on several high-profile projects throughout North America. They are available to rent, allowing customers to try before they buy.
