Firestone control panels will allow you to monitor the PSI that is inside of your air springs. There are single and dual gauge options that are available in white or black. There are options for systems that have a tank (pneumatic) as well as systems that do not (electric).
So, to be clear:
- Single control panels inflate and deflate one pair of air springs
- Dual control panels inflate and deflate two individual air springs or two pairs of air springs
- Pneumatic control panels are used in any air compressor system that utilizes a tank
- Electric control panels do NOT require the use of a tank
