GAS INPUT CONNECTIONS

Supply the Pro-Cut 55 with clean compressed air or nitrogen.

Supply pressure must be between 80 psi and 150 psi.

Flow rate should be approximately 6.0 cfm (170 I/min.).

NOTE: Oil in the air supply to the Pro-Cut 55 can cause severe problems. Use only a clean air supply.

Connect the gas supply to the Pro-Cut 55’s pneumatic nipple at the air filter. See Figure A.3.

Compressed gas should be supplied to the fitting connection mounted on the filter at the rear of the machine. If necessary, this fitting can be removed allowing plumbing access through the 1/4 in. (6.4mm) NPT input port on the filter body.
