The screw compressor is one of the compressors that is a subset of the positive displacement compressor, and the function of these compressors is to suck air in and compress the air with the help of an electric motor, air generator, cooling and filtration system, and the compressed air It makes the required output ready for that industry. The difference between screw compressor and other compressors and used industries: Compared to rotary and piston compressors, these compressors have better performance with lower electricity consumption and less noise and vibration. They are used in various industries for air compression. Compressors play an important role in various industries and this type of screw compressor can be used in industries such as automotive, electronics, aviation (gas condensate and gas storage), chemical (turbine engine) industries.

Screw compressors are divided into two categories:

1. Oil-injected screw compressor
2. Oil Free screw compressor

Definitions of the components of the screw compressor:

Screw compressors are divided into two categories:

1. Oil-injected screw compressor
2. Oil Free screw compressor

Definitions of the components of the screw compressor:

1. Electromotor: These motors are defined according to the amount of the tank and the power of the air generator, and its power consumption is basically the act of starting the first one and providing power to do the work with the electric motor.
2. Airend or air generator unit: this device has the task of producing compressed air and has a direct connection with the electric motor. The power transmission                    between the electric motor and the air generator unit is divided into three parts:                split coupling, belt and gear.
3. Air filter: These filters are for air filtration from gases, which if this action is not done correctly, it will cause irreparable damage to the device.
4. Separator filter: This filter separates oil particles in the air to deliver completely clean and usable air for that industry at the outlet.
5. Oil filter: The main job of this filter is to separate the particles and pollution in the oil, and if this action is not done, it will cause a lot of damage to the internal parts that        need lubrication and quality oil, and it will reduce the lifespan of the parts.
6. Bearings: Bearings have a significant effect in reducing the decibel of the device's sound and also reduce the depreciation of the device.
7. Drain valve: The function of this valve is basically to drain the accumulated liquids or moisture of the device, which is done mechanically and automatically, and plays a significant role in the quality of the output air.
