Mobile, capable of pumping and receiving oil, with three gears for adjusting vacuum pumping and increasing vacuum pumping to drain oil

Aluminum alloy vacuum generator, fast vacuum reduction, zero faults

Once the vacuum is filled, the air source can be disconnected, which does not waste compressed air, reduces noise, and eliminates the phenomenon of muffler spraying oil mist

The measuring cup container is made of tempered glass, which is resistant to corrosion, high temperature and aging. The oil level scale is carved by laser, which is precise and high-definition
