When a sufficiently hard abrasive particle strikes steel, it deforms the surface into a valley and pushes up peaks. The distance between the top of the peak and the bottom of the valley is known as the depth profile. In the U.S., the depth profile is measured by mils – thouhs of an inch.In the metric system, the micron(one millionth of a meter) is used.

Comparing Pressure VS Suction Blast Cabinet, pressure blast cabinets are known for providing a much higher speed. Another difference between pressure blast and suction blast is in the speed of throwing out the blasting media. The abrasive media delivering speed is twice than those of suction blast cabinets.

Industrial blasting gun bodies of suction cabinet blast systems range between 12 to 38 SCFM. The pressure blast cabinet systems range between 12 to 68 scfm and the pressure blast room systems use up to 254 scfm. Industrial air compressors produce approximately 4.5 SCFM per horse power (hp).

The pressurized air pushes the abrasive at faster velocities than suction systems. Many processes can be completed 30-50% faster with a direct pressure blaster. Due to the higher flow rate (and more force), pressure blasting offers the additional advantage of allowing for lower blast pressures ideal for delicate and sensitive surfaces.

When it comes to the best blasting system for the job there are several variables to consider, including suction vs pressure blast systems, media type, budget, desired surface finish, etc. So let's look at some of the advantages and disadvantages of Dry Blasting vs Wet Blasting in a blast cabinet for an industrial environment.
