THIS NRP8DI LIGHT-WEIGHT, INVERTER-DRIVEN, DUAL-STAGE VACUUM PUMP DELIVERS HIGH-SPEED EVACUATION ALONG WITH HIGH ULTIMATE VACUUM. VACUUM MEASUREMENT TECHNOLOGY PRECISELY MEASURES THE SYSTEM PRESSURE. A DIGITAL DISPLAY PROVIDES A COMPREHENSIVE VIEW OF THE SYSTEM’S INTERNAL VACUUM CONDITION. SMART CONTROL ASSURES THE SYSTEM’S VACUUM BY AUTOMATICALLY EXTENDING THE EVACUATION TIME AFTER THE SYSTEM REACHES THE PRESET VACUUM LEVEL. A BUILT-IN SOLENOID VALVE PREVENTS OIL BACK FLOW AND SEALS THE SYSTEM TO PRESERVE THE VACUUM DURING POWER OUTAGE OR ACCIDENTAL DISCONNECT. UPON COMPLETION OF OPERATION, THE UNIT WILL BEEP TO REMIND THE TECHNICIAN THAT EVACUATION IS COMPLETE, SO THEY CAN MOVE ON TO THE NEXT JOB.
