Most smaller blast cabinets include trigger guns. Larger cabinets usually include a Foot Pedal Control. When you pull the trigger or press the foot pedal, the result is the same: abrasive is pulled up through the gun and “blasted” at the part, instantly removing rust, paint, and scale. The results are the same, but for more than occasional use, we recommend the use of a foot pedal control to minimize operator hand fatigue.
