THERE ARE SO MANY COMPRESSOR OPTIONS.. HOW DO I CHOOSE?

Compressors are responsible for the grunt work in any airbag system, they are responsible for making sure your air tank(s) are full of compressed air ready to air up your bags when needed.

Should you go with 1 or 2+ compressors? You only need 1 compressor for your airbag system to work but using 2 compressors has its benefits. Using 2 compressors will fill your air tank(s) faster and limit the time your compressors have to run. Having 2 compressors will also give you a backup compressor in the very unlikely event that a compressor fails you will still be able to fill your tank(s).  

Several factors come into play when choosing the appropriate air bag compressors for your particular application. Some of the most important things to consider when choosing an air compressor are the compressors duty cycle, horsepower, and CFM that the compressor is able to produce. The duty cycle, or efficiency, of air bag compressors can be defined as the amount of time that the air compressor can operate under load (pumping at high psi) verses the time when operating under no load (low psi). For instance, an air compressor rated at “100% duty cycle” can run continuously, even when under load. An air compressor rated at “50% duty cycle” would mean that this compressor can only run under load half the time. In other words, a 50% that is going to run for a total of 10 minutes should run a combined maximum of 5 minutes on and then off for 5 minutes. In this example, a 50% duty cycle compressor can run for 5 minutes to fill your air tank up to pressure, but then must be off for 5 minutes while you use the air in the tank to fill your bags. If a 50% compressor is run constantly, like that of a 100% duty compressor, the compressor will have to work too hard, which will cause overheating, and will drastically reduce the life of the compressor. So, if you plan to play with your air ride all day long at a car show or while crusin’ the strip, you should consider spending a little more for a compressor with a higher duty cycle rating.

What does CFM mean?? ... An air ride compressor CFM rating tells you how many Cubic Ffeet per Minute that the compressor can fill at a particular psi. For example, a compressor may be able to flow 4 CFM at 0psi tank pressure, but at 100psi tank pressure, the compressor can only flow 2 CFM since the increased tank pressure will make the compressor have to work harder. CFM can also be referred to as the flow rate. The higher the CFM the faster your tank(s) will fill. Higher CFM's usually equal a louder compressor; however the Air-Zeith OB2 does not apply here due to the higher grade quality components and design.
