Brushless Motor Vacuum Air Pump DC 12V -80KPa Micro Diaphragm Negative Pressure Suction Pump

Specification (As a reference): Demolition color new high flow 12-24V brushless air pump vacuum pump, motor color is very good, in and out of the air pipe interface inside very clean, is fully sealed semi-finished module overall demolition, the air pump can be said that basically not how to use or is a new machine demolition of the air pump also comes with metal bracket and other accessories, do not need to use a screwdriver to dismantle the part of the air pump to remove the self-contained plugs already! Cut out, or the air pump import and export of this white plastic block does not come with, there is no requirement on the random shipment, the default air pump with bracket together with the shipment, if you need to remove the bracket shipment you can contact the owner, there are still with the sealing of the shell accessories assembly, the plastic shell bulk more or less will be a little bit of a few scratches, the two specifications according to the needs of the purchase. This high-power high-flow brushless air pump is not common, the motor is inner rotor with drive brushless motor, motor diameter of about 42mm, basically the same size as the brush 775 motor, has been counted as a relatively large small crankshaft diaphragm vacuum pump.

The actual test of the pump performance is also very good, air pump above the nominal 12V, check the information this air pump supports 12-24V voltage work, the air outlet can be blocked 12V voltage test, positive pressure of 0.18M pa, negative pressure maximum -80kpa, 24V voltage test, positive pressure can be blocked limit of 0.25M pa, negative pressure -82kpa, 24V voltage test flow rate of about 6L/per minute. Brushless motor built-in drive circuit, so you must use 12-24V DC regulated power supply, can not use a simple transformer plus rectifier is not a regulated DC power supply, prohibited the use of overvoltage, the motor positive and negative line is strictly prohibited to connect the wrong, will burn the drive
