  • Pressure drop, a forgotten problem

    A pressure drop is when there is a pressure difference between the air that leaves the compressor and the air that reaches the point-of-use. The point-of-use can for example be an air blow gun or an air knife. It is not unusual that the pressure has dropped 1 Bar (14.5 psi) before it reaches the final user.
