Adopting oil-free piston pump
Clean-without pollution of oil and smoke
Convient-no need add oil to maintain daily
Safe-no plus pressure during using
No regorging-keep pressure when the machine stops, so the liquid won't flow backwards

Complete plastic panels,hand-switch and foot-switch for operating easily.Select negative pressure at will with no level for pressure adjustment,and overflow protection mechanism,safe and reliable.
Principle technical data:
Max negative pressure:≥0.09MPa
