NAVTEK NP4DP 4cfm Dual Voltage Vacuum Pump
2 Stage (twin cylinders) for high ultimate vacuum down to 15 microns
Integrated cylinder structure coupled with forced oil circulation assure its high performance and reliability.
Gas ballast Valve: simply open the gas ballast on startup, when the pump changes note and quiets down close the ballast valve to allow normal performance, effectively this process vents the initial high volume of moisture laden air out of the vacuum pump for a few seconds, before it gets chance to contaminate your oil and turn it a milky white.
Built-in hook makes it easier to carry to a high workplace.
