65-120Kpa DC12V 6W Mini Vacuum Negative Pressure Suction with Holder for ysis Sampling

Micro- is powered miniature DC motor drive, drive internal mechanical eccentric eccentric motion, driven by an eccentric movement inside the diaphragm reciprocates.Whereby the chamber fixed volume of air compreion (compreion suction port is closed, the exhaust port is formed to open slightly positive preure), stretching (compreed exhaust port is closed, a negative preure sucking mouth open), the ing air intakes with the outside atmospheric preure difference, at a preure difference, the preure (suction) into the chamber, and discharged from the exhaust port.Micro- is mainly used for , ysis sampling, instrumentation and other fields. Completely maintenance-free, and no oil , do not pollute the nsmiion medium.Small, stable and reliable, hand-held instrument for -priming, low noise, low power consumption.
