Central Pneumatic Air Compressor

With most lower cost compressors you MUST pay attention to the duty cycle. You can not run most of them pumps all the time. You will burn them out. If it has a 30% duty cycle,you can only have the pump running 30% of the time. Runs for a minute it must cool off, not running, for two minutes. If you only need small volumes of air these are fine. Air grinders, sanders and lots of spray guns eat up lots of air in a hurry. Good rule of thumb is to buy the biggest one you can possibly afford.
