WORKING PRINCIPLE

Step	Description
1. Rotor Design	The blower consists of three intermeshing lobed rotors (typically in a figure-eight shape), which rotate inside a casing without touching each other.
2. Air Intake	As the rotors rotate in opposite directions, they trap a fixed volume of air between the lobes and the casing, drawing air in through the intake port.
3. Compression	The trapped air is moved toward the discharge side. As the rotors continue rotating, the volume between the lobes decreases, compressing the air.
4. Air Discharge	Compressed air is expelled through the outlet port at a higher pressure. The constant flow rate is maintained despite pressure changes due to positive displacement.
