Failure to comply with ANY NOTICE listed below could pose a hazard to personnel or property.

 

See Air & Abrasive Consumption Chart for estimated abrasive consumption rates and required air flow 

(cubic feet per minute). Your system must meet these minimum requirements to ensure proper function and 

performance.

 

When it comes to air & abrasive mixtures, more is not necessarily better.  Optimum abrasive blasting efficiency 

takes place when a lean air & abrasive mixture is used. To correctly set the abrasive metering valve, begin 

with the valve fully closed and slowly increase the amount of abrasive entering the airstream. As you increase 

the abrasive flow, watch for a “blue flame” at the exit of the abrasive blasting nozzle. Faster cutting, reduced 

abrasive consumption and lower clean up costs, are benefits of the “blue flame”.

 

Abrasive blasting at optimal pressure for the abrasive used is critical to productivity. Example: For an abrasive 

with an optimal abrasive blasting pressure of 100 psi at the abrasive blasting nozzle, one pound per square inch 

of pressure loss will reduce abrasive blasting efficiency by 1.5%. A 10 psi reduction in air pressure will cause a 

15% loss of efficiency. Use a Needle Pressure Gauge to identify pressure drops in your system. Consult with 

your abrasive supplier for the requirements of your abrasive.

*Abrasive consumption is based on abrasive with a bulk density of 100 lbs per Cubic Foot

Inspect abrasive 

blasting nozzle before 

placing into service. 

Damage to abrasive 

blasting nozzle liner 

or jacket may occur 

during shipping. If you 

receive a damaged 

abrasive blasting nozzle, 

contact your distributor 

immediately for 

replacement. Abrasive 

blasting nozzles placed 

into service may not 

be returned. Abrasive 

blasting nozzle liners 

are made of fragile 

materials and can be 

damaged by rough 

handling and striking 

against hard surfaces. 

Never use a damaged 

abrasive blasting nozzle.

Replace abrasive 

blasting nozzle if liner 

or jacket is cracked 

or damaged. Replace 

abrasive blasting nozzle 

if original orifice size 

has worn 1/16” or more. 

Determine abrasive 

blasting nozzle wear by 

inserting a drill bit 1/16” 

larger than original size 

of abrasive blasting 

nozzle orifice. If the 

drill bit passes through 

abrasive blasting nozzle, 

replacement is needed.
