FARR Application Focus on Blasting Sizing Recommendations
Wheel Blasting generates a very concentrated dust stream compared to room air blasting. The blasting media is usually steel shot. The dust that makes it to the dust collector is a combination of carbon mill scale, steel powder, and rust. The density is several hundred pounds per cubic foot. When cleaning carbon steel, a GS with Hemipleat cartridges can run about 1.5 to 2:1 AC ratio. If the process runs 24 hours a day, then you should be around 1.5:1. We also recommend the abrasive resistant inlet option to extend filter life. When blasting SS, we recommend staying at or below 1.5:1. Consult factory if blasting anything unusual like plastic or specialty alloys. These materials may be flammable and extra precautions are needed. Also, adequate ventilation of the blast chamber is required or overheating can occur quickly. When applying a dust collector on this application, you must make sure the minimum airflow is maintained to keep the air stream under 150 deg. F
Room Air Blasting - When sand or grit blasting AC ratios can be up around 3:1 for most applications. There is much more dilution air compared to wheel blasting. Temperature is also generally not a concern.
The main caution is blasting aluminum. Extra safety precautions must be taken like x-venting and placing the collector outside.
The Gold Series has proven itself to work very well on difficult Laser and Plasma Cutting applications. The Gold Series works on applications where most other dust collectors have failed.

Gold Cone Cartridge
GS
60 on Sand Blasting
Camfil Farr Gold Series cartridges have an expanded capacity due to the patented inner Gold Cone. This inner cone increases media area and provides uniform dispersion of back-pulsed air. It also opens up more useable space for air flow in the filter.
