Control Your Sandblasting Air Pressure With These Tips
Air pressure is one of the most integral parts of sandblasting. Without the optimal amount of pressure, your desired level of blasting cannot be completed. At Kramer Industries, we are long-time experts in all blasting systems. If you’re looking to increase the efficiency of your system, check out our tips.
What Sandblasting Air Pressure Is Required?
The blast pot requires a minimum of 50 PSI. This measure will allow the pop-up valve to seal and the internal pot to pressurize. While operating, the pressure of the pot will typically in the60-80 PSI range to ensure the most efficient amount of blasting. Once pressurized, the pot needs to maintain its airflow to keep that minimum level of 50 PSI.
What Happens if Pressure is Not Maintained?
If your system cannot handle the amount of air flow coming through, the pop-up valve will likely unseal and any internal pressure will be lost. Typically, if you are using a high-pressure system, an additional 20-25 CFM’s is needed to supply enough air pressure.
Achieving Optimal Air Pressure
To achieve maximum sandblasting performance, we’ve outlined some tips to keep in mind as you are completing your project. Following these guidelines will help achieve best performance.
- Regularly clean your blast pot. Contaminants will make proper metering difficult and increase the generation of dust.
- Use a clean, dry nozzle to ensure proper air supply. While higher air pressure often produces greater productivity, it also increases particle breakdown and shorter media life.
- Set the metering valve by closing it, then slowly open while blasting. This introduces the abrasive to the air stream to help you find the optimal balance.
While it might be tricky at first, maintaining optimal sandblasting air pressure is essential to getting your desired results. Our team will equip you with the right blasting system and all the necessary components you need to finish your job right
