8 Compressor Frequently Asked Questions Professional Answers

Q: After the compressor is turned on, it looks like it is working, but there is actually no air coming out. What can we do about it?


  • Check the ultimate safety valve

     Whether the knob position on the top of the ultimate safety valve has been screwed to the top. If not, please turn it counterclockwise to the topmost position and try again.



Q: The set pressure of the compressor is obviously 330bar, why can't the air be charged when it is charged to 20bar?


 

  • Check the ultimate safety valve

       Is the safety valve leaking, has it been screwed all the way? The knob on the top of the final safety valve is not set to the operating position, please turn the knob to the operating position.

 

  • ​Check the extension board

    At normal temperature, the maximum length of the external cable (three-phase motor) is 25m.



Q: The compressor cannot be started



  • Check the phase sequence

    If the compressor has phase sequence protection and the phase sequence is reversed, the phase sequence protection indicator light of the start machine will turn on red.
    Swap any two connectors of the three-phase connector in the switch box. Remember, the connectors cannot be swapped in the junction box of the motor.

     

Q: Why does the equipment keep low oil pressure alarm?




  • Check if the motor is reversed

      Make sure that the direction of the motor is the same as the direction indicated by the arrow on the sticker on the device. If you find that the steering is inconsistent, adjust the phase sequence.
That is, exchange any two joints of the three-phase joint in the switch box. Remember, the joints cannot be exchanged in the junction box of the motor.

 

Q: Why does the motor have no response after turning it on?




  • Check if the phase sequence is reversed

If the compressor has phase sequence protection and the phase sequence is reversed, the red light of the phase sequence protection indicator lights up after starting the machine, and the motor cannot run.
Swap any two connectors of the three-phase connector in the switch box. Remember, the connectors cannot be swapped in the junction box of the motor.
 


Q: Why does the pressure gauge not reset to zero?



 

  • Check that there is still gas in the hose.

If there is air in the hose, the pressure gauge cannot be 0.
Open the inflation valve again, let the air out of the inflation valve and the inflation hose and look again.
 
Slight errors are common in operation and can be ignored, but if the error is too large, the pressure gauge must be replaced.
 


Q: When inflating, there is no air pressure coming out of the inflation tube, the pointer of the pressure gauge does not move, and it will automatically stop.



 

  • Please pay attention to check the voltage

Please use a 230V, 16A socket, a multi-strand cable with a size of more than 4 square meters, and do not use a drag line socket.

Q: Is the filter cartridge leaking?




  • Check if the filter element is installed

If not, please install the filter first

  • Check that the O-ring of the filter element is intact

Replace O-rings if damaged or broken
