Low Pressure Centrifugal Blower

Low Pressure Centrifugal Blower

A low pressure centrifugal blower is a fan designed to operate with a total pressure below 1000 Pa. These blowers are known for their large airflow, low noise, and low power consumption. They are ideal for applications such as ventilation, air exchange, and air conditioning systems. Typically, they utilize direct drive transmission, making them suitable for environments that require smaller airflow and lower air pressure. Their simple structure ensures ease of maintenance and cost-effectiveness.

Working Principle

The basic structure of a low pressure centrifugal blower includes:

Motor

Shaft

Impeller

Volute

When the motor drives the shaft to rotate, the attached impeller spins at high speed. The blades on the impeller force the air or gas entering the fan to move outward in a radial direction, generating centrifugal force. As the gas is flung toward the edge of the impeller, its velocity increases, resulting in a corresponding rise in pressure. Finally, the gas is guided through the volute structure and discharged from the outlet, completing the process of gas compression and transport.
