Sizing a tank for your use
An air tank supplies pressure for whatever you connect, so the tank size and the demand of your application should match. Air tools and tire inflation draw air differently than horns or leveling air springs, so think through how often and how long you will run the system before choosing a setup.
A compressor and tank system works best when the lines, fittings and wiring are sized and secured for the job. Keep the tank mounted firmly, route lines away from heat and moving parts, and make sure any fuse sits close to the power source.
- Match tank demand to how you will use the air
- Route lines away from heat and moving parts
- Mount the tank firmly
- Keep the fuse close to the power source
