Screw compressors offer a great number of advantages which other kinds of compressors, including the piston-type compressors, do not. There are many firms like compressed air that provide rotary screw compressors.

Operation of a rotary screw compressor
The rotary screw compressor has 2 rotors that can push air through it. The pressure is hence created. The compression of air is achieved and created by the secondary and main rotors that synchronize and mesh with each other in a housing of dual bore and one-piece design.
In the water-injected or the oil-free designs, the fluid gets introduced in the second step of compressor operation. This removes the compression heat and also seals all the internal clearances. The injection of the fluid also prevents any kind of metal or rotor contact.
Some designs of rotary screw compressors are oil-free. In these designs, the rotary shafts have the timing gears attached to them. They prevent the two rotors from contacting each other. Water can be injected into the"compression" chamber so that sealing and cooling can be provided at higher temperatures.
The new screw compressors have the electronic panels for control. These panels offer clear and precise graphics and are quite intuitive and user-friendly in their design. The new interfaces can also be easily combined with the computers, the setpoints, and the operation conditions of the compressor while the other configuration parameters are all clearly and specifically displayed in alphanumeric and easy-to-comprehend" alphanumeric displays and readouts.
