– Air Pump,12V DC Mini Electric Vacuum Pump Micro Air Pumping Motor Ultra Silent Operation Enhance the Power for Aquarium Tank Medical Treatment Instrument and Other Fields

I'm going to use this vacuum pump to powered a brake bleeding kit that I'm in the process of making. The suction appears sufficient for my needs and the vacuum produced is consistent. This could also be easily adapted to use as an air pump for aquariums and the like. Connections are easily identified by the positive connector having a red dot adjacent to it. I would consider that it would also work if connected incorrectly with air traveling in reverse, but it's not recommended to do this, as damage may occur i would suppose.

Good quality air pump

Good value for money. I put 3 in series and obtained a scientifically measured vacuum that would require a far far more expensive alternative to achieve. Will buy again. Great for science experiments.

Highly recommend. Used this for a surface mount component pick up tool, far superior to the vacuum bulb type. However, don’t use aquarium air line tube it will collapse under the strong vacuum. I used a thick wall silicone tube; sourcing map 2mm (ID) x 6mm (OD). It’s a tight fit but doesn’t collapse at full vacuum.

Would buy again

Pump lasted all off 35 days before failing used to airyate a small fish tank
