Concave Blade

Specifically designed for better distribution of abrasive on smaller parts

Cleaning is the result of transferred energy from the abrasive to the work piece. The correct size of abrasive is typically the smallest size capable of cleaning the work piece. This assures optimal coverage for the energy required.

Abrasive breakdown is a result of energy transfer. Increasing the velocity without decreasing shot size will result in increased cleaning energy and higher shot consumption. Unless the additional energy is required to clean, there is an implied loss of potential productivity improvement due to less than optimum coverage for the energy required.

A combination of high velocity and small abrasive size provides for the optimal combination of cleaning energy and coverage.

Previous wheel velocities did not produce the energy levels required to achieve the desired cleaning results with small abrasive sizes. Through wheel innovation, velocity in excess of 360 feet per second will drive the use of smaller abrasive size in achieving the optimal combination of


The narrow pattern of the focus blade provides the following:

  • Increase concentration of abrasive on smaller parts
  • Provides better cleaning of narrow pieces, equaling fewer multi passes
  • Less blast on cabinet liners outside the work piece
  • No need for expensive blast intensifier assemblies

The concave blade provides an effect that results in narrow line of the blast pattern that reduces the shot on shot interference from rebound back into the shot stream.
