DC 3V-6V Micro Vacuum Air Pump – Self-Priming, Negative Pressure, Used – Unbranded
About this item
Alright, this one’s used, but it’s got life left.
DC micro vacuum pump, runs on 3 to 6 volts.
Self-priming, pulls negative pressure, max vacuum over -350mmHg, max pressure over 600mmHg.
No brand name, MPN not listed—it’s a generic shop pump.
Might have a few scuffs from sitting on a bench or being a floor model, but it fires up fine.
Great for DIY projects, lab stuff, or replacing that one pump you thought was discontinued.
Made in China, does what it says.USD$ 3.45
