Mil Profile:
3.5-4.5
Nozzle (min):
5/16”

1240 produces a moderate profile and is used for a near white blast. Blast through medium to heavy coatings, heavy rust, and heavy mill scale. 1240 is often used for general purpose repair and maintenance blasting of coated steel surfaces.

Mil Profile:
3-4
Nozzle (min):
5/16”

1630 provides similar cutting efficiency as 1240 with the smoother profile associated with 2040. 1630 is used for surfaces with medium to light coatings.

Mil Profile:
2-3.5
Nozzle (min):
1/4”

2040 is used to remove light rust, mill scale, enamels, and acrylics. 2040 produces a moderate profile and is used for white to near white blast, often for new construction, special maintenance applications requiring reduced profiles, exposed aggregates, bridge maintenance, new structural steel, and more.

Mil Profile:
1.5-3
Nozzle (min):
1/4”

2850 provides similar cutting efficiency as 2040 while achieving the more precise profile of 3060. 2850 is used on new steel or surfaces with light coatings to achieve a moderate to slight profile.

Mil Profile:
1-2.5
Nozzle (min):
1/8”

Clean surfaces and create a smooth finish for a variety of applications. 3060 produces a slight profile for a near white blast finish and is ideal for light rust and mill scale removal. It can also be used in wet abrasive applications.

Mil Profile:
.75-1.5
Nozzle (min):
1/8"

4080 offers the delicacy for glass etching, can brush surfaces clean of light rust, and is used for light cleaning of new steel, household, automotive, or farm equipment to create a smooth finish with a slight profile.
