Introduction
Compared with traditional belt drive or direct drive air compressor, our oil-free air compressor (hereinafter referred to as air compressor) do not require lubricating oil and can provide a relatively clean air source with low noise. This is especially suitable for dentistry, breeding, medicine, fitness, beauty, chemical industry, scientific experiments, and other high-demand fields.
At the same time, it can also be widely used in traditional home improvement, auto repair, factories and other fields. Such as air supply for pneumatic tools, like spray gun, air nailer, etc., air supply for vehicle brakes, air supply for tooling equipment, etc.

Operation
Applicable Model:2-900F8
1.safety valve (Pic. E):
Safety valve ① is mainly used to keep the air pressure stable. When the air pressure exceeds 10 bar (15 bar for high-pressure models), it will automatically release the pressure to protect the safety of users. Caveat! The safety valve cannot be used to deflate. Frequent pulling out of the safety valve can easily damage the safety valve.
2. Pressure gauge (Pic. E):
The air compressor is automatically controlled by a pressure switch during normal operation. When the pressure reaches the maximum value, it will automatically stop, and when the pressure drops to the starting pressure, it will automatically start. The working pressure of the air pressure switch has been adjusted before leaving the factory and cannot be changed at will during use. The pressure is displayed by the pressure gauge ②.
3. Power connection:
Plug in the plug and turn on the power (power must be grounded). Note: The air compressor should not be placed too far away from the power source (within 10 meters), so as not to reduce the voltage of the motor.
4. Pressure switch (Pic. F)
Vertical switch:Pull up the switch button to turn on, and press the button to turn off. Horizontal switch: Turn the switch to AUTO to turn it on; turn the switch to OFF to shut down.
5. Air outlet (Pic. E)
- The ball valve ③ can be used directly.
- before using the quick connector ④make sure there is no pressure in the air tank.
6. Movement
Before moving the compressor, make sure that the switch is off and the power cord plug is unplugged from the socket. Grasp the handle, lift the air compressor, move the air compressor to the desired position, lower the handle, and ensure that the air compressor is on a flat ground. Note:Make sure your feet stand firm and seek help if necessary.
7. Overload protection (Pic. G)
This product is equipped with an overload protection device. When the working voltage is too low or too high, or the working environment is with high ambient temperature, the motor is overheated, the machine will automatically cut off the power supply to protect the motor. After that, the user needs to turn off the power switch first, wait for 3–10 minutes, and then press the red reset button (depending on the cooling condition). Then turn it on, the machine can be used normally. If the button is reset, it still does not work normally. Wait for 30 minutes or more, and then start the motor after it has cooled down completely.
Applicable Model:2-900F18/2-1450F/2-1800F35
1. Safety valve (Pic. D):
Safety valve ①is mainly used to keep the air pressure stable. When the air pressure exceeds 10 bar (15 bar for high-pressure models), it will automatically release the pressure to protect the safety of users. Caveat! The safety valve cannot be used to deflate. Frequent pulling out of the safety valve can easily damage the safety valve.
2. Pressure gauge (Pic. D):
The air compressor is automatically controlled by a pressure switch during normal operation. When the pressure reaches the maximum value, it will automatically stop, and when the
pressure drops to the starting pressure, it will automatically start. The working pressure of the air pressure switch has been adjusted before leaving the factory and cannot be changed at will during use. The pressure is displayed by the pressure gauge ②.
3. Power connection (Pic. E. F):
(1)The specifications of the air switch connected must be more than 50%higher than the rated current of the air compressor.
(2)The air compressor has a standard grounding device, connect the ground
wire before use. Note:The length of the power cord shall not longer than 10 meters, If you need toextend it, please use a power cord with a higher diameter.
4. Pressure switch③ (Pic. D):
Pull up the switch to turn on, lower the switch to turn off.
5. Air outlet (Pic. D):
(1)The ball valve④ can be used directly.
(2)before using the quick connector ⑤make sure there is no pressure in the air tank.
6. Movement
Before moving the compressor, make sure that the switch is off and the power cord plug is
unplugged from the socket. Grasp the handle, lift the air compressor, move the air compressor to the desired position, lower the handle, and ensure that the air compressor is on a flat ground. Note: Make sure your feet stand firm and seek help if necessary.
7. Control box (pic. G)
(1). Each motor has an independent control switch. When it is started normally, motors will start in sequence with a delay of 4 seconds. The user can also set the number of working motors according to actual work requirements.
(2). Phase sequence correction, if the electric control box displays “999” after the power is turned on, but it does not work normally:it is because the power input line is connected
incorrectly, and the motor is in phase sequence protection state to avoid motor reversal, and the wiring sequence needs to be re-adjusted for normal use.
(3) Over-voltage and under-voltage protection
The air compressor will automatically cut off the power to protect the motor due to the high or low input voltage. The user needs to make sure that the voltage is normal and then restart the machine. Warning! Please use the air compressor in a suitable environment!
Maintenance
Before any maintenance or repair work, you must cut off the power supply and ensure that the air tank is pressure-free, otherwise it is very easy to cause injury!!
- Please clean and maintain the machine regularly.
- If the power cord is damaged, in order to avoid danger, it must be replaced by the manufacturer’s maintenance department or qualified person.
- Open the drain valve to drain the water daily or after every use. When draining, the pressure in the air tank should be less than 1 bar.
- Check whether the safety valve is sensitive every week, pull out the safety valve to check whether it can be easily exhausted, and it can be reset immediately after pressing it.
- It is recommended that remove the filter element of the air alter and clean it with clean high-pressure air every 200 hours of use. Replace the filter element of the air filter every 500 hours of use and replace the cylinder and piston ring every 2000 hours of use. The details can be adjusted according to the actual use.
- The air tank shall be subjected to a pressure test every two years, and the internal and external surfaces shall be inspected once a year. When there is severe rust, severe bruising or failed to pass the pressure test, the air tank shall be replaced.
- In case of severe machine vibration, please pay attention to whether you need to replace the shock pad.
Precautions for maintenance:
- Before disassembling the machine, cut off the power supply, wait for the machine to cool down and ensure that the air tank is pressure-free.
- During the maintenance process, the fasteners should be tightened, if any damage is found, they should be replaced with new ones.
- when the maintenance is over, after re-installation, the fan should be rotated to check for abnormalities
Note:The left and right fan blow inward when the motor rotates.
