What is the abrasive blend knob?
The abrasive blend knob can be a bit of a mystery. What’s the right setting? How far can I turn it clockwise? Will opening it create a richer abrasive stream? Every blaster is configured to a specification. This means the tank orifice, the nozzle, and the blast pressure have been carefully selected for the application. When the abrasive blend valve is fully closed, which happens when the knob is in the max position, leave it there! This position allows the most abrasive to flow through your blaster. The richness of the abrasive stream is ultimately determined by the tank orifice, where the abrasive enters the air stream. Watch the video to learn more!
Need a Calibration Cap?
If several operators alternate use of your blaster, and you see a difference in abrasive flow between users, then a calibration cap is a good idea. A calibration cap locks this knob into the maximum position and reduces variability operator to operator.
