Review on 💨 Miniature Vacuum NW 5V 6VDC, 100KPa Pressure by Mike Anderson

Used as a vacuum pump for Chinese microdermabrasion sticks. At 6V DC (a handy wall wart) a nominal suction of 40kPa (nominal pressure 100) was achieved exactly (the pump is rated for 4.5V DC), the current is much lower than the maximum, so overvoltage doesn't seem to be at least a suction problem. 40 kPa is 18 inches Hg. Art. and home use microdermabrasion devices are usually rated for 25 inches Hg. Complete sets of local production. Further studies show that 40 kPa is effective and is the lower limit of standard diamond microdermabrasion devices. The seller was absolutely honest and detailed in the description.
