90kW Roots Blower Sand Suction Machine

The VR90 Abrasive Vacuum Recovery System is designed for fast and efficient recovery of steel shot, steel grit, garnet, quartz sand and other blasting abrasives from blast rooms, shipyards, tanks, workshops and industrial sites. Using a powerful pneumatic vacuum conveying system, the machine collects used abrasive through wear-resistant suction hoses and transfers it directly to the storage silo for recycling and reuse. This significantly reduces manual cleaning work and improves abrasive recovery efficiency.
