Wetblast Injector System

Tongbao’s Wetblast Injector System adds the dust-suppressing power of water to any pressure blast machine.  The Wetblast injects a small amount of water into the high-velocity abrasive/air stream just before the nozzle.

This hard-hitting mixture of water and abrasive cleans and keeps dust levels under control.

The Wetblast System introduces water into the abrasive/air stream before it passes through the nozzle orifice.  This results in a complete wetting of each abrasive particle, unlike with water ring systems.  The Wetblast controls airborne dust far better than water ring systems.

Portable Suction Blast and Vacuum System

Air powered mobile dustless abrasive blasting equipment with superior productivity, suction power and separation efficiency.

Tongbao's Vacuum Blaster units are suitable for different purposes and applications, and have superior suction power and separation efficiency. The units are based on pressure vessels in combination with compressed air filters and pressure regulators that ensure sufficient speed of operation in a dust free environment. tongbao has been operating in the field of environmental equipment for more than 20 years, and has extensive experience in equipment and systems for blasting applications. The Vacuum Blaster comes complete, mounted on a trolley with a grit separator, silo with an internal sieve, filling valve, efficient vacuum producer and compressed air filters. A pneumatic valve in the bottom of the silo empties the dust into a plastic bag. Furthermore, the unit is equipped with a pneumatic control device for automatic filter cleaning. The Vacuum Blaster also comes with a 10 m hose with a blasting and suction head. The capacity of the vacuum unit is determined by the maximum blast pressure and the type of blasting abrasive used. The sieve ensures that bigger extracted particles can not enter into the blast vessel. The filling cone is pushed up by the blasting abrasive and the lid above it ensures sufficient clearance to eject the abrasive.

Internal Pipe Cleaning Tools 

We are offering a comprehensive range of Internal Pipe Cleaning tools, which is mainly designed to blast clean without the necessity of rotating the pipe. These cleaning tools help in removing rust, old paint and other contaminants from the pipe better than any other method. Our cleaning tools have replaced the conventional blast nozzles as these are powered by compressed air. In these tools, the abrasive is accelerated and propelled through specially designed nozzles that clean the pipe with ease.   

Blast Machines Accessories

Blast Nozzles, Nozzle Holders,

Hose Coupling, Blast Hoses and  Remote Control System

Tongbao Equipment offers our blast machine accessories and spares to meet most users’ blast equipments and their applications. All remote Control Systems can be easily fitted to any Standard Blast Pots. Please check with us on the suitability of using our blast pot accessories and spares for your existing blast pots.

Blast Machines and other makes (brands) can be fitted easily with either our air or electric-operated remote control system. The remote control system gives each individual blaster instant starting and stopping capabilities without the need of pot-tender. This results in no wasted abrasives, increased rate of production with maximum safety. Our remote control system effectively reduces labour cost, improves the efficiency of abrasive usage, performance and operator safety.
