Here are some possible reasons for the decrease in air volume of the Roots blower in aquaculture

1. Blockage in Inlet or Outlet Ducts: If there are contaminants or foreign objects blocking the inlet or outlet ducts of the Roots blower, it can hinder air circulation, thereby affecting the normal operation of the blower and reducing its airflow.

2. Fouling on Blower Blades or Deformation of Impellers: After prolonged use, the surfaces of the blower blades can accumulate dirt, leading to fouling and subsequently reducing the airflow. If the impellers of the Roots blower deform, it can affect the clearance between the impellers and the casing, also resulting in reduced airflow.

3. Motor Damage or Bearing Wear: The motor and bearings in a Roots blower are vital for maintaining normal airflow. If the motor is damaged or the bearings are worn, it can also impact the airflow of the blower.

4. Clogged Filters: The airflow of a Roots blower can be affected by the filters. If the filters are not cleaned or replaced for an extended period, they can become clogged, thereby reducing the airflow of the blower.

Therefore, when a decrease in airflow from a Roots blower is observed, it is necessary to promptly investigate the aforementioned issues and perform corresponding maintenance and repairs specific to aquaculture applications.
