Lobe type rotary air compressor, in its simplest form, consists of two rotor lobes rotating in an air-tight casing which has inlet and outlet ports.
There are many designs of wheels, but it generally has two or three lobes.
The lobes are so designed that they provide air tight at the point of their contact.
The arrangement of lobe type rotary air compressor , The mechanical energy provided to one of rotors from external source, while the other is gear driven from the first
As the rotor rotates, the air at atmospheric pressure is trapped in the pockets formed between the lobes and casing.
The rotary motion of the lobes delivers the entrapped air into the receiver.
Thus more and more flow of air into the receiver increases its pressure.
Finally the air at higher pressure is delivered from the receiver.
