Product Description

ROOTS BLOWER

The 3-lobe version of the Roots blower was developed as a refinement of the original 2-lobe design. It aimed to address some of the limitations in terms of efficiency and performance, particularly in specific applications where greater flow stability, lower pulsation, and improved power efficiency were needed.

• The 3-lobe design offers several advantages over the 2-lobe design, including:
  1. Reduced Pulsation: The third rotor reduces the vibration and pulsation commonly found in 2-lobe blowers, resulting in smoother operation.
  2. Higher Efficiency: The 3-lobe configuration leads to better airflow control and generally operates with less power consumption for similar output, making it more energy-efficient in certain conditions.
  3. Improved Durability: With a more balanced design, the 3-lobe blower can experience less wear and tear over time, improving the unit's lifespan.

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.
