Vacuum Recovery Manual Sand Blasting Machine With Automatic Abrasive Reclycle By Vacuum Air
The vacuum recovery manual sand blasting machine (also called dustless vacuum sand blaster or closed-circuit manual sand blaster) is a portable, closed-loop surface treatment device that integrates blasting, vacuum recovery, abrasive separation, and dust collection. It solves the dust pollution and abrasive waste problems of traditional open sand blasting, making it ideal for indoor, confined-space, and precision surface treatment scenarios.
Core Capabilities
Closed-Circuit Dustless Operation
- The blast head (with a brush seal) creates a local negative pressure zone, instantly vacuuming dust, used abrasives, and debris into the recovery system—no dust overflow, meeting strict environmental and occupational health standards
- Suitable for indoor workshops, confined spaces (tanks, pipelines), and sensitive areas (hospitals, food factories) where dust is prohibited
High-Efficiency Abrasive Recycling
- Used abrasives are sucked back, separated from dust/impurities via a cyclone + screen separator, and returned to the blast pot for reuse. Recycling rate ≥90%, drastically reducing abrasive consumption and operating costs
- Supports most abrasives: steel grit/shot, aluminum oxide, glass beads, walnut shells, baking soda, etc.
Manual Flexibility + Precise Control
- Handheld blast gun with adjustable nozzle (flat/round/angled) for 360° treatment of complex surfaces (corners, holes, welds, profiles)
- Blasting pressure (0.4-0.8 MPa) and vacuum suction are independently adjustable, adapting to light deburring, heavy derusting, paint stripping, and surface roughening
Portable & Easy Maneuverability
- Compact design with wheels/casters; can be moved freely in workshops or on-site (shipyards, bridges, construction sites)
- Quick setup: no fixed foundation, connect to compressed air and power to start
Safe & Low-Maintenance
- Interlock protection (blast/vacuum sync), emergency stop, and filter clogging alarm
- Modular design for blast gun, filter, and separator; quick replacement of wearing parts (nozzles, brushes, filters) reduces downtime

Typical Applications
Widely used for small-to-medium workpieces, on-site maintenance, and confined-space treatment across industries:
- Shipbuilding & Offshore Engineering - Rust/paint removal on ship hulls, tanks, pipelines, and offshore platforms; surface preparation for coating in confined cabins
- Petrochemical & Energy - Cleaning storage tanks, reactor vessels, heat exchangers, and pipeline inner/outer surfaces; descaling and paint stripping in explosive-risk areas (optional explosion-proof models)
- Construction & Renovation - Concrete surface roughening, old paint/coating removal on bridges, buildings, and facades; historical building restoration (low dust)
- Automotive & Machinery Maintenance - Paint stripping on car bodies, chassis, and engine parts; derusting of molds, gears, and hydraulic components
- Aerospace & Precision Manufacturing - Surface cleaning of aircraft parts, precision components, and molds (dust-free to avoid contamination)
- General Industrial Maintenance - On-site repair of steel structures, metal furniture, and equipment; deburring and oxide removal for small batch parts
