• Description: OOTDTY -Micro-pump is powered miniature for DC motor within mechanical eccentric motion, driven via an eccentric movement inside the diaphragm reciprocates. -Whereby the chamber constant volume of air compression (compression suction port is closed, the exhaust port is formed to open slightly effective pressure), stretching (compressed exhaust port is closed, a adverse pressure sucking mouth open), the pumping air intakes with the outside atmospheric strain difference, at a stress difference, the gasoline strain (suction) into the chamber, and discharged from the exhaust port. -Micro-pump is principally used for medicine, gasoline analysis instrumentation and different fields. -Completely maintenance-free, and no oil don't pollute the transmission -Small, secure and reliable, hand-held device for pump-priming, low noise, low calories consumption. Especially like minded for top unfavourable 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 photo shows Color: as picture displays Package include： 1 Micro Vacuum
