Suction Blasting Cabinets

Suction Blasting Cabinet for Sale

Suction Blasting is based on Injection Suction principle of blasting. It works on the venturi principle to get abrasive from a non-pressurized storage hopper to the blast gun where it is mixed with the compressed air stream and propelled against the work surface or blasting surface. Suction blast machines are most easily recognized by having two hoses (one for air and one for abrasive media) running to the blast gun.

When we are working with a suction-blast gun, it is easy to recognize, because it has two pipes attached to it, one providing compressed air and one vacuum pipe (abrasive blasting hose) is bringing media into the gun. Pressure-blast nozzles have only one larger pipe to deliver a mixture of media particles and compressed air.

The suction blasting cabinet system uses the venture principle, integrating an air jet one half the inside diameter of the nozzle. This creates a negative pressure in the pipe that sucks the abrasive media into the gun body from the media containing hopper. A suction blaster can operate continuously without shutdowns to refill abrasive media in the storage hopper and can be easily operated with multiple guns over multiple bodies.

Suction blast cabinets provide the ideal cleaning, smoothening and finishing solution to many coating, painting and corrosion problems. They are ideally used for ensuring a decorative or naturally pleasing surface finish across many materials. Suction systems are generally have lower capital cost than a pressure cabinet and use less compressed air, making them appropriate for smaller workshops or lower production environments.

Suction blasting cabinet features

• Suction blasting cabinets are of lower cost than the similar sized pressure blasting cabinets.
• Suction blaster has far fewer moving parts and valves than a pressure abrasive blast unit, therefore, more easy maintenance and trouble shooting is possible there.
• Less air and abrasive consumption is there in an ejection gun (suction abrasive blast gun) as its air demand is governed by the abrasive air jet, which is almost half the size same of the blast nozzle diameter.
• Continuous blasting is possible in a suction blasting cabinet because we need not to think to refill the abrasive media containing hopper again and again in this, whereas in a pressure blast system the continuous blasting time is decided by the amount of abrasive media present in the storage hopper or pot present at one time.
