What is the correct air pressure setting for the ProBlue 10?

The ProBlue 10 should be connected to a dry, nonlubricated air supply capable of providing a maximum of 6.2 Bar (90 psi). The initial operating air pressure should be set to 1.4 Bar (20 psi), but this should be adjusted later to meet your manufacturing process requirements. The minimum operating air pressure is 0.7 bar (10 psi); operating below this may cause the pump to function erratically.
