(See the video on the page for details.)
- For the most stable and reliable performance, we recommend using an 850 PSI air tank https://mcsus.com/products/mcs-13ci-air-tank-with-integrated-on-off-slide-valve-3000psi-850psi-output-air-tank-regulator

VIEW INSTALLATION AND OPERATION VIDEO:

==============================
We recommend keeping your air tank pressure around 900 psi, as this provides the best balance of stability and reliability.

This is the best tank option for this setup:

Higher-pressure tanks may still work; however, they increase the risk of blowing an O-ring, and O-ring replacement may become necessary more often.
