Special design protects the environment and provides clean filtered oil to the pump while it also prevents oil spray and oil flowing back into the system. Alloy aluminum casing and direct drive design make for a compact and light but durable pump. Comes with gauge.

•Oil Capacity 200ml

(We have has some questions about the Ultimate Vacuum produced by this pump.  The vacuum unit used in the specification is Pa, short for Pascall. This is a unit of pressure measurement like bar, psi,  or atm.  A single pascal represents very little pressure, one pascal is just  0.0001450 PSI.  100,000 pacals is equal to normal atmospheric pressure of 14.5038 PSI. 0 pascal would be a perfect vacuum.
