This pressure increase is very effective. Don't compare it with the cheaper products of the same trade. It's definitely not a grade. This manual control motor speed.
This kind of modification is more violent, and the wind pressure is very high. Suitable for customers who require high performance improvement

Step
The first step is to insert the three-needle plug into the out position of the tester. The white line is on the s-pole.

There are three rows of arbitrary plugs in one row, and the knob is set to the minimum position.
The second step is to weld the three rows of motor wires with the three wires adjusted by electricity without any color difference.

After welding, tape should be wrapped to prevent short circuit.
The third step is to connect a DC 12 volt power supply to an electrically regulated red connection positive pole and a black connection to the negative pole.

After power on, the motor will make a sound, stop ringing after a few seconds, then slowly twist the knob of the tester to start the motor,

the normal operation of the wind is from the motor tail discharge, if not to indicate that the motor reversed, the need to remove two of the motor wires to adjust and then welding,

then the motor works properly.
