Method 1: test the air compressor at the ON/OFF working Load is mainly considered as a small air compressor Pistons, but if a large air compressor with this behavior, use the same method.
One way to test the air compressors that run ON / OFF Load mostly small air compressor such as piston. But if large air compressor with this behavior. The same way
Test method 1 compressed air at work ON / OFF Load mainly as compressed air small remember the piston. But if the air compressor with large characteristic function works the same way.
