The 5 Basic Elements of an Airless Blast System

1. One or more airless blast wheels for propelling the abrasive by centrifugal force in a controlled pattern and direction.
2. A Cabinet that contains the abrasive material as the blast wheel performs its cleaning action.
3. A work handling system to present the work to be cleaned to the abrasive action of the wheel[s].
4. An abrasive cleaning and recycling system to transport, condition and clean the abrasive, removing contaminants and fines from the useful abrasive before going back to the wheel[s].
5. Dust Collector to remove all dust and abrasive fines from the blast machine and environment for a clean and safe operating environment.

What is Airless Blasting?

The introduction of the airless blast wheel was a major revolution for the blast cleaning Industry. Instead of using compressed air to propel abrasive, the abrasive is thrown from a rapidly rotating wheel onto the work to be cleaned.

The throwing action is achieved through a centrifugal force, where a wheel with radially located blades is rotated at high speed. Onto the revolving wheel, abrasive is fed in such a manner that it travels along the radial length of the blades and is thrown off in a high velocity stream at the surface to be cleaned.
