Structure & Working Principle
The product structure is mainly composed of a piston cylinder, a liquid
storage bottle andsupporting frame.
Press the handle to produce negative pressure by means of the piston's
reciprocating motion in the cylinder. No any positive pressure will be
generated in the aspirating system due to utilization of unidirectional valve,
leading to safe & reliable operation.
With compact structure，easy operation，convenient for trnsportation.
