30 hp rotary screw air compressor has the air flow with 3.8m³/min @7bar. That is about 134 cfm. And this 22kw air compressor is fixed speed type. Of course, if you want the variable speed screw compressor, we also produce it. As a manufacturer, we provide good 30 hp screw compressor price.
In addition, this is a direct drive rotary screw air compressor. It’s not belt driven air compressor. Compared with the latter, the former is easier to maintain. Because belts are prone to wear and tear, we need to replace it from time to time. The former motor is directly connected with the airend rotors through a coupling. Thus, there is no need transmission gearbox. So greatly improve the transmission efficiency.

Why choose our industrial 22kw air compressor
(1) Two years warranty screw compressor airend
Firstly, our 30hp screw air compressor uses the famous SKF brand bearings. So the airend has reliable quality. And our airend adopts high-efficiency tooth shape. The flow channel has been specially optimized. It has large rotor and high efficiency. High reliability provides a strong heart for the air compressor.
(2) The 30 hp rotary screw air compressor is with microcomputer control system
Because of the intelligent control system, it has self-diagnosis and protection functions. For example, the panel can display the actual operation of the 22kw air compressor. When a failure occurs, the screw compressor will respond accordingly. Moreover, the system can display the replacement parts in time. Also inform us to make necessary maintenance. In addition, the computer system has a spare output. The input terminal can realize chain control of multiple air compressors. So guarantee safe operation 24 hours a day.
(3) Built-in efficient oil separation system
Our 22kw air compressor adopts high-efficiency oil-air separator. It can achieve three separations. That is, centrifugal separation, gravity separation and filtration separation. Firstly, the compressed air is mixed with lubricating oil. They rotate in an oil mist separator. Separation occurs by centrifugal force. Secondly, after being centrifuged, the oil impacts the inner wall of the cylinder. Due to gravity, it settles to the bottom of the oil and air cylinder. Finally, the cylindrical filter element with fiber as the main body collects the atomized lubricating oil. So play the role of filtration and separation.
(4) Low noise design
Our 30 hp rotary screw air compressor adopts silent design. The sound-absorbing structure is optimized. There is preset large volume front air filter. Airflow is smooth. So reduce noise and airflow loss to a low level.
How to maintain the 30 hp rotary screw air compressor
Firstly, the 22kw air compressor runs for about 500 hours. At this time, need to replace the lubricating oil and oil filter. At the same time, check the operation status of the 30hp air compressor.
Secondly, the air compressor runs for 2000 to 3000 hours or half a year. At this moment, we should replace the air filter and oil-air separator. Also clean the air-cooled cooler.
Thirdly, the air compressor runs for 3000 to 6000 hours or a year. At this time, should maintain several valves. Namely intake valve, minimum pressure valve, oil stop valve and exhaust check valve.
Finally, the air compressor runs for 6000 to 9000 hours or two years. At this moment, need to replace thermostatic valve core. Also clean the impurities and carbon deposits in the oil circuit.
Q1: Is this 22kw air compressor power frequency or variable speed type?
A1: This 30 hp rotary screw air compressor is without inverter. Of course, if you need the PM VSD screw compressor, we also manufacture it.
Q2: What’s the oil content of your 30hp screw air compressor?
A2: The oil content of compressed air is less than 3ppm.
Q3: What about the warranty time of your 30 hp rotary screw air compressor?
A3: The whole machine is 1 year and the airend has two years warranty.
