5. Fieldpiece VP55 Two Stage 5 CFM Vacuum Pump
Fieldpiece VP55 – 5 CFM Vacuum Pump Fieldpiece VP55 – 5 CFM Vacuum Pump x 5 CFM, two stage vacuum pump 4 Inline Ports – 1/4, 3/8 (x2), 1/2 Change Oil Quickly, Even with the Pump Running Heavy Duty Rubberized Construction Fieldpiece is leading the charge in properly performing system evacuation with its new vacuum pumps with RunQuick Oil Change System. Available in an 8 CFM DC motor (model VP85), or in a 5 CFM AC motor (model VP55), these revolutionary pumps make evacuation easier and faster. Good oil is a key ingredient of every evacuation. Clearly view your pump oil through the huge oil reservoir window to see the condition of the oil, and the system. When it’s time to change the oil, it’s quick, clean, and easy. With the RunQuick oil change system you can replace the oil in under 20 seconds, even while the pump is running without losing vacuum. Plus the extra wide base helps prevent tipping and spilling oil. Four in-line ports give you tidy hose routing for three different size hoses. Place the cord on the handle for tangle-free storage and easy hoisting.

Safety Standards for Design and Production:
(1) The pressure measured by the digtal manifold pressure tester is gauge pressure.
(2) Pressure testing ranges from -101Kpa to 6Mpa (-0.1bar to 60bar).
(3) The limit pressure is 10 Mpa (100 bar).
(4) The maximum operating pressure of standard hose is 600 PSI ( approximate 4.13 Mpa, 41.3 bar ). The limit pressure is 3000 PSI approximate 20.68 Mpa, 206.8 bar ).
(5) Please confirm the rated pressure value of the tested equipment before testing. Do not use it if it exceeds the range of the instrument. Also for DY517A, if the packed hoses does not match the pressure requirement, you can use suitable replacements for testing.
(6) Do not use and store the instrument in high temperature, high humidity, flammable, explosive and strong electromagnetic fields.
(7) Please do not change the instrument internal circuit, to avoid any damage of the instrument or danger occurring.
