Company Profile

Automatic Sand Blasting Machine with Integrated Vacuum Recovery, PLC Automatic Control, and 90% Abrasive Recycling Rate

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

Equipped with brush sealing structures, the blasting nozzle forms a local negative pressure area on the workpiece surface. Dust, spent abrasives and residues are immediately extracted and delivered into the recycling system to prevent dust leakage, fully complying with stringent environmental regulations and workplace occupational health requirements.
It fits perfectly for indoor workshops, confined operating environments such as tanks and pipelines, as well as dust-restricted sensitive sites including hospitals and food processing plants.

High-Efficiency Abrasive Recycling

Recovered used abrasives are processed through cyclone separation and screening devices to filter out dust and impurities, then sent back to the abrasive storage tank for cyclic reuse. The abrasive recycling rate reaches no less than 90%, which greatly cuts material consumption and overall operational expenses.
The equipment supports a wide range of abrasive media, covering steel shot, steel grit, alumina abrasive, glass beads, walnut shell media, sodium bicarbonate and more.

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

Models & Specifications

Typical Applications

Widely used for small-to-medium workpieces, on-site maintenance, and confined-space treatment across industries:

Shipbuilding & Offshore Engineering - This equipment is used for rust elimination and old paint stripping on ship hulls, storage tanks, pipelines and offshore platforms. It also delivers professional surface pretreatment for coating construction inside enclosed ship cabins.
Petrochemical & Energy - It is widely applied to clean the inner and outer surfaces of storage tanks, reaction kettles, heat exchangers and various pipelines, completing descaling and paint removal work. Explosion-proof customized versions are available to meet the safety requirements of construction sites with explosion hazards.
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
