Abrasive Blasting 101| Maintenance Tips
Blasting cabinet filters can be one of three types: Air Inlet Filters, Air Regulator Filter, and Dust Collector Filters. Dust Collector filters come in two main materials: cloth filters or cartridge filters. Dust Collector Filters are the most important.
Buy the most dust collector filter area, measured in square feet, you can find for your spending budget. This is because the more filter area, the less filter cleaning is required and the slower the air speed through the filter. This equals better filter performance.
Real World Example: Purchased a Blasting Cabinet that has the gun cfm size, blower size, separator reclaimer, and filter area size all matched together for your DDC, Daily Duty Cycle, you will have a great blasting experience, great visibility, and a clean area. The cartridge allows for semi-automatic cleaning using a vibrator or reverse pulse cycle using compressed air. All this is better than wiggling a manually operated handle back and forth used in the same era as tube radios. This also means slower air velocity, better filter efficiency through the filters, easier cleaning and a clean area around the cabinet.
There are lots of different blasting cabinet filters. Plan to change your filters, any type, yearly if you use your blasting cabinet. Some filters using the large industrial gun sizes may need changed more often. Keep in mind that using a filter 20 times smaller means you should clean the filter 20 times more often. Also, easy-to-clean cartridge filters are more likely to be property maintained than other filters. Finally, never use wet air in a dry blasting cabinet, it turns any filter type to plugging mud.
Media Blast’s production machines and negative pressure dust collectors are easy to service and offer a larger filter dust storage area for maximum use between filter cleanings. If you’re not sure which blasting cabinet is right for you, check out our buying guide or give us a call!
