Side Channel Blower vs Roots Blower it’s a question the public likes to hear about.Both of them are currently common industrial blower types in the market.

With the passage of time, more and more side channel blower has slowly begun to replace Roots blower process.

Today we will do a comparison of Roots blower and side channel blower.

side channel blower vs roots blower

How it works

Roots blower: A Roots blower is a positive displacement blower that generates airflow through two meshing screws. When the screw rotates, the gas is sucked in and compressed from the suction end, and then pushed out the vent end.

Side channel blower: The side channel blower is a centrifugal blower that accelerates the gas by centrifugal force and produces high pressure air flow in the centrifugal housing.


Pressure range

Roots blower: Roots blowers are usually used in the low to medium pressure range, and their output pressure is generally between 0.1 and 1.2 bar (approximately 1.45 to 17.4 psi).
Side channel blower: The side channel blower is designed to provide higher outlet pressure, and its output pressure can often reach 2 bar (approximately 29 psi) or more.


Flow range

Roots blower: Roots blowers perform well in small and medium flow ranges and are suitable for applications that require large amounts of gas flow.
Side channel blower: The side channel blower typically provides high pressure gas over a relatively small flow range and is suitable for applications requiring high pressure output.


Energy Efficiency

Roots blower: Roots blowers usually have low energy efficiency and their efficiency is relatively low, especially under partial load.
Side channel blower: side channel blower has higher energy efficiency to a certain extent, especially under high pressure conditions.


Noise

Roots blower: Roots blowers generally produce high noise levels, especially at high speeds.
Side channel blower: side channel blower produces lower noise than Roots blower in general.


Applications

Roots blower: Because of the small flow rate and low pressure characteristics, Roots blowers are widely used in sewage treatment, waste gas treatment, power stations and other fields.
Side channel blower: The side channel blower is suitable for applications requiring high pressure gas, but the blower itself can be applied to three dimensions through regulation.


Overall, side channel blower is significantly better than the Roots blower in terms of pressure range, energy efficiency performance, noise level, and volume performance.
When users need higher requirements and higher performance,

Side Channel Blower will be a better choice, it can bring more efficient and stable solutions for industrial production.
