产品特点
主要技术参数

1. Product Introduction
Type B sandblasting gun is a siphon negative pressure sandblasting gun, widely used as a replacement gun for cabinet sandblasting machines. It adopts internal mixing sandblasting design. Compared with Type A gun, it has a larger inner flow channel, which allows delivery of coarser abrasives. It is mainly made of die-cast aluminum alloy for dry blasting. It can also be customized into polyurethane versions for wet sandblasting as required.
2. Core Structure & Dimensions
- Structure: Larger inner cavity than Type A gun. Equipped with fixing lugs for easy mounting on sandblast cabinets. Total length: approx 95mm, gun body thickness: 40mm
- Material: Die-cast aluminum alloy (standard); Polyurethane (optional for wet blasting)
- Interface: External thread connection, pagoda joint optional; sand tube core diameter: 16mm; air core outer diameter: 20mm
- Nozzle: Interchangeable boron carbide or tungsten steel nozzles; nozzle bore size 6–12mm available
- Weight: About 0.55kg
3. Performance Parameters
- Working Principle: Negative pressure siphon (suction feed)
- Working Air Pressure: 0.4–0.8 MPa
- Applicable Abrasives: Coarse and medium abrasives, brown corundum, white corundum, steel grit, quartz sand, etc.
- Spraying Distance: 100–400mm
- Compatible Equipment: Dry box sandblaster, semi-automatic sandblasting equipment
- Consumables: Nozzle, air core protective rubber sleeve
4. Product Features
- Large internal flow channel, stable sand feeding, suitable for medium & coarse abrasive blasting
- Aluminum alloy gun body, robust and durable, with mounting lugs for simple installation
- Simple siphon structure, easy disassembly and maintenance; replaceable wearing parts to cut operation cost
- Higher sand output than Type A gun, improves working efficiency for heavy cleaning work
Model Comparison Tip: Type B for medium / coarse sand; Type A for fine sand and delicate surface finishing; Type C is small size with low flow for light blasting jobs.
5. Application Fields
- Castings & forgings: Heavy rust removal, scale cleaning, deburring
- Steel workpieces: Remove old paint, oxide layer
- Foundry industry: Clean casting flash and residual sand
- Heavy hardware: Surface pretreatment before coating
- Stone material: Surface roughening and carving
6. Operation Notes
- Suitable for medium and coarse abrasives; avoid ultra-fine powder sand which may reduce blasting efficiency
- Compressed air must be dry to prevent sand agglomeration and pipe blockage
- Inspect nozzle regularly. Replace immediately once worn out to maintain blasting effect
- For wet blasting environment, select polyurethane version to avoid corrosion
