Extended use of the Roots blower can lead to insufficient air pressure, which can affect the efficiency of the machine's operation. So, when faced with insufficient air pressure during use, how should we handle the situation?

The main reasons for the insufficient air volume of the three-blade fan can be categorized into the following three points:

Firstly, the import blockage causes insufficient air intake during the machine's operation.

Solution: Remove the sponge from the intake vent and clean it; this will allow the fan to maintain normal airflow.

Next, the internal lubricant of the fan may degrade or become depleted, both of which can lead to insufficient air volume. Therefore, it's crucial to always check the lubricant in the fan during operation.

Ultimately, belt slippage and loosening can also cause insufficient airflow in fans, and it is important to adjust the belt promptly when this occurs.

Furthermore, other issues may arise during the operation of the centrifugal fan, so it is crucial to maintain and service the machine regularly.
