DC 12V Mini Noiseless Vacuum Pump Negative Pressure Suction Pump 5L/min 80kpa
A part of the review has been auto-translated.
Un buen motor, nada fuera de lo común, causa buen vacío aunque para mí le falto pero es útil y un poco ruidoso pero en general lo recomiendo
Erhalten wie bestellt.
High quality, compact and very silent pump, which is working from 4.5 V and more. Consumption at 12 V remains bellow 0.6 A and motors stays cool, vacuum achieved is 0.25 atm, overpressure about 4 atm (life-time of membrane gets shortened though). Worth for replacement of water pump in laboratory in connection to suction filtering or like source of vacuum for desoldering station or in robotics https://www.youtube.com/watch?v=86G9DLJEagw. It can pump water as well https://www.youtube.com/watch?v=3QIvr_HUMvw principle of function https://i.imgur.com/OE4zyQ4.gif
good product
Terrific motor with air pump and suction. Unit works relatively quietly and supplies both pressure with flow and negative pressure. Great for testing automotive diaphragm valves and mechanisms.
works well, it’s been running for a while now. deceptively good product. I’m happy
works great. packaging couldve been better
After 40 hours without stopping, it's good to smoke, but maybe more.
Roger, not tried, little little
low noise. works well
