• Description: OOTDTY -Micro-pump is powered miniature for DC motor internal mechanical eccentric motion, driven via an eccentric movement contained in the diaphragm reciprocates. -Whereby the chamber fixed number of air compression (compression suction port is closed, the exhaust port is shaped to open barely nice pressure), stretching (compressed exhaust port is closed, a destructive stress sucking mouth open), the pumping air intakes with the outside atmospheric pressure difference, at a strain difference, the gas pressure (suction) into the chamber, and discharged from the exhaust port. -Micro-pump is particularly used for medicine, gas evaluation instrumentation and other fields. -Completely maintenance-free, and no oil do not pollute the transmission -Small, regular and reliable, hand-held device for pump-priming, low noise, low energy consumption. Especially appropriate for top damaging environmental requirements. Specification: Brand new Type: DC12V Mini Vacuum Operating Rated Positive pressure: 8000mmHG Negative pressure:-500mmHG Rated Current: 350mA Rated Power: 20W Suction capacity: 8L / min Inlet diameter：6mm Outlet diameter: 6mm Vacuum degree: 66kpa Maximum pressure: 120kpa Noise:<60db Size: as photograph reveals Color: as picture displays Package include： 1 Micro Vacuum
