A portable air tank is an air compressor that features a tank to store compressed air in. There are air compressors that do not have tanks, such as what you may have seen people keep in the trunk of their car for inflating tires. Traditional air compressors are usually far too heavy to lug around. They also vary in size and are just not practical for easy transportation.
There are a lot of different kinds of tools that use a compressed air tank, such as nail guns, paint sprayers, staple guns, sanders, and more. Air compressors are also good for cleaning and obviously filling up tires too, so they’re incredibly handy to have for do-it-yourself projects and a variety of other situations.
How to Use an Electric Air Tank
The vast majority of air tanks are powered through an electrical plug. Operating an electric one is simple. First place it on a level surface, and then check the pump oil level to make sure it’s sufficient. Connect your air hose if it’s not already connected. After activating the compression switch, the tank will automatically stop running once it reaches the pressure it was set to as long as the ‘auto on’ setting is activated on the pressure switch box. It will also automatically refill when the pressure falls below the set amount. Attach the tool you want to use, if any, and set the suggested PSI for operation with your specific tool.
When you’re finished using the air compressor, turn the air pressure relief valve to bring the PSI back down to 10 pounds or less. Some people choose to leave their tank already full of pressurized air for certain periods of time. This is a matter of preference, but for safety reasons and also to protect the integrity of your equipment, it’s better to release most of the pressure every time you turn it off. Next, open up the lower tank drain valve to release any built up moisture in your tank, and then it will be ready to be put away.
