Compressed air is useful in filling up bike or car tires. It is also a good clean-up tool. You can use it to blast away dust from tubes or other difficult places to reach. Compressed air is available in gas stations. But if you have a portable air tank, you will have compressed air on hand any time you need it.

A portable air tank should have components that will make it safe and easy to use. An air pressure gauge will make sure that you achieve proper inflation pressures. It should be easy to read. The air shut off valve stops air from leaking out of the tank when not in use. The pressure tank is what holds the compressed air and should be pressure tested for safety. You can have compressed air stored for months.
