Product Features
Durable, efficient and stable air end 
1. The design idea of "large rotor, large bearing, low speed" is adopted to
reduce noise and vibration and increase the life and stability of the host.
2. The tooth surface is processed by the German KAPP rotor grinder to create a
high-precision rotor, which is the first guarantee of high efficiency and
stability of the air end.
3. Adopt a new type of 5: 6 asymmetric rotor tooth shape, high-precision three-
coordinate measuring machine for comprehensive measurement, increase the air
capacity by 5% -10%
4. All imported quality bearings are used.

Specialized motor for air compressor 
1. Imported brand bearings, protection class IP54, insulation class F, suitable
for harsh environments such as large dust and high temperature.
2. IE3 high-efficiency motor uses less electricity and reduces your cost of
use.
3. The motor is designed according to the 1.2 coefficient, and the starting
torque is large, which can meet the requirements of full life use under various
working conditions.
High-quality and efficient coupling 

1. The coupling is a torsionally elastic coupling with failure protection
function, which can effectively damp and reduce the vibration and shock
generated during the operation. 
2. The elastic body is only under pressure and can withstand greater loads. The
drum-shaped teeth of the elastic body can avoid stress concentration.
Stable and reliable electronic control system 

1. The control system has the functions of voltage detection, three-phase
unbalance detection, overpressure, overtemperature, overload, and overrun alarm
high alarm functions, real-time protection of the unit, automatic monitoring of
operating conditions, automatic loading and unloading, sleep and restart And
other functions, no need to be supervised by someone.
2. The standard Internet of Things system allows you to see the running status
of your machine on your phone.
3. The intelligent control system can be set in both Chinese and English, and
can realize the joint control of multiple units.
4. Choose high-quality electrical components, and the contactors are imported
brands.
5. Emergency stop function, a push-type emergency stop switch is installed in a
prominent position of the unit, and it can stop immediately in an emergency.

Inner rotor fan 
1. IP44 cooling fan, Class F insulation;
2. Compared with the outer rotor fan, the inner rotor fan has higher air
pressure, more air volume, and better cooling effect;
3. Due to high wind pressure, the cooler and filter are less likely to be
blocked

Three filters 
Air filter: the filter area exceeds 150% of the normal requirement, low the
inlet pressure loss , and high energy efficiency ;
Oil filter: The design of the imported oil filter with enlarged glass fiber
material is adopted. The rated processing capacity of the oil filter is ≥1.3
times of the circulating oil volume. The filtering accuracy is high and the
durability is good.
Oil separator: imported glass fiber material oil core, good filtration effect,
low oil core pressure loss.

Inlet valve 
Inlet valve: low flow speed test, low pressure loss, reduce energy
consumption;
Minimum pressure check valve: low pressure loss, precise control, ultra-fast
repositioning to ensure that the user's air does not return.
Temperature control valve: Mixed flow temperature control valve: The unit is
equipped with a mixed flow temperature control valve to ensure that the unit is
more convenient to start in a low temperature environment, and to ensure the
unit is in the best performance state by controlling the oil supply temperature
of the air end

Oil-injected screw compressors use oil to lubricate, seal, and cool the
compressor components during operation.
Our Oil-Injected Compressor is engineered for high-performance applications
that require reliable and powerful air compression. Ideal for industrial and
commercial use, this compressor utilizes an oil lubrication system to enhance
efficiency, extend the lifespan of the machine, and provide optimal cooling
during operation.
Choose our Oil-Injected Compressor for a powerful, efficient, and reliable
solution to all your air compression needs, ensuring your operations run
smoothly and effectively!
