Please note these tables highlight the actual requirement and are only a guide.
It is always advisable that your supply exceeds this as there could be other uses and discrepancies, and therefore exceeding the required power, free air delivered (FAD) and volume of air is necessary.

Here are 9 critical points to help you get the most out of air blasting:
1. Ensure You’re Working To The Correct Parameters.
3. Choose The Smallest Media That Will Do What Is Required.
5. Media Flow Regulation Requires To Be Optimised On A Pressure System.
6. On The Venturie / Suction Delivery System Alternative Regulation Requires Attention.
7. Surface Consistency And Repeatability.
8. Nozzle And Air Jet Size Compatibility On A Venturie Fed System.
9. Quality And Delivery Of Your Compressed Air.
All dry blast systems require dry, oil free air delivered to the process. Small amounts of moisture and oil cause the media particulates to stick together and prevent the free flow of blast media.
Check and make sure that the air jet and nozzle bore sizes are optimised. It is a fact that when checked many venturie blast systems have air jets and nozzles that are entirely miss-matched.
Depending on the air blast process desired, (i.e. a cleaning operation only or surface preparation prior to bonding) it is desirable to maintain and repeat the surface finish time after time.

Under the blast media hopper, placed under the base of the cabinet floor or under the cyclone unit, you will find the blast media pick up device, referred to in our introduction Part 1. There are several designs on the market each purporting their advantages, however, in principle they almost always work the same, some designs better than others. It is important to understand how this simple but effective pick up method works as this is critical to the process.
To draw both blast media and air in through this pick up device, it requires to be set up by adjusting the air to media ratio. Once fixed, this is set and need not be changed until another blast media or size is required.
