Some people install the compressor in a remote place and if it is new, they install it on the tank and store it in the garage.
If tank replacement is not the cheapest option, make sure you have a non-destructive testing laboratory near you that can provide this service. To inspect your tank, perform an ultrasonic thickness inspection and measure the wall thickness. If you have high-pressure washers, you can also test them with a hydro- or high-pressure cleaner on the bottom of the compressor tank.
In this case, I estimated the tank at 175 PSI, so I doubled the maximum working pressure and checked it with a high-pressure cleaner at the bottom of the compressor tank. After doubling the 175 psi to 350 psi, connect the pressure to the tank and fill it FULLY with water and run for a few minutes to double the maximum operating pressure. Once the air line (s) are disconnected, note how long it took to build up the tank pressure by disconnecting it.
To determine whether the air compressor is working properly, you can test it with a high-pressure cleaner at the bottom of the compressor tank and then with the tank.
If your compressor has its own oil supply, check the oil level before driving and the oil level after driving. If the test period is well behind you, contact an authorized ROLAIR Service Center in the USA or Canada.
The governor controls when your air compressor pumps air into the air tank and out of the tank. When the pressure in the air tank increases, the governor stops pumping the air through the compressor, and when it drops to a limit pressure of 100 psi, it allows the compressors to pump again.
Werther recommends draining the tank cleaning water from the condensation water, which is produced when air is sucked into the compressor tank. Pull the safety valve ring outwards to release pressure from the tank and the valve should close automatically. Inspect for damage or cracks, as well as for leaks and leaks of any kind.
Werther insists proper safety equipment and glass are warned before oil is checked - free air in the compressor. If your compressor has its own oil supply, check the oil level before driving and check the oil level before driving.
The governor controls when an air compressor pumps air out of the air into the air reservoir. When the pressure in the air tank increases, the governor stops pumping the air through the compressor, and when the pressure in the tank drops to a limit value - 100 psi, it allows the compressors to start pumping again.
Note: Maximum pressure means that the safety valve relieves the pressure in the air tank, not the actual pressure of the compressors or the air reservoir. To test the tank, first removing all safety valves and other relief devices and installing a pressure gauge that is known to be accurate, you must test it at 1.5 times the maximum pressure. You can also test your tank with the same pressure as air tanks, but at a lower pressure.
For this reason, pressure testing of compressed air is always performed underground in bunkers. If one or even a tiny section fails, the pressure can tear through the tank and tear it apart, as it is higher when a large area fails due to an explosive release. You can also test the vessel under water, which should fill completely with water at high pressure.
A pump of sufficient size and motor is much more important, because even if you produce as much air as you want to consume, it will quickly run out, no matter how small the tank is. All you get is a water leak, and water is not compressible, so even a tiny leak can reduce the pressure of the entire tank, especially if you have only got water that is leaking.
However, there are cases where you can save money by getting a smaller compressor with a larger tank and using air only occasionally. If you have a compressor that continuously produces 10 CFM, it will only get 20CFM out of the tank. However, if you need to operate intermittent or smaller compressors with larger tanks, you do not have enough air in the tank to do this, so you need to have both.
You do not need an air compressor permit, but if you need one, it is available from the Federal Aviation Administration (FAA) or your local city or region.
This approval is required if your air receiver has a maximum operating pressure of 150 psi and contains more than 1,000 pounds of air per square inch (psi). If you need even more air, you can minimize the need for approval and inspection by choosing an air receiver tank that has a maximum operating pressure (PPI) of less than 200 psi and contains at least 100 pounds (60 psi) or less. Fortunately, those who do not exceed the maximum operating pressure (PSI) for their air compressor tank will receive a one-off authorisation (a so-called permanent authorisation) at the first inspection.
