The critical component for maintenance and upkeep of the medium-efficiency exhaust fan housing is the impeller. It is essential to inspect for cracks, wear that requires replacement, and accumulation of dust that needs cleaning. These conditions can disrupt the balance of the impeller, leading to vibration in the rotor of the medium-efficiency exhaust fan housing, which can ultimately cause damage and reduce the original working lifespan of the medium-efficiency exhaust smoke fan housing.

In addition, it is crucial to maintain the bearings of the medium-efficiency exhaust fan housing. Regularly check the lubricant supply for the medium-efficiency exhaust fan housing bearings and replace the lubricant at scheduled intervals. This can indirectly enhance the working efficiency and lifespan of the medium-efficiency exhaust fan housing.

External maintenance primarily involves monitoring environmental temperatures to prevent freezing in the medium-efficiency exhaust fan box and addressing surface hygiene issues on the medium-efficiency exhaust smoke fan box. Cleaning off surface dust ensures that both the intake and exhaust airways remain clean, facilitating better ventilation. Maintaining cleanliness also effectively reduces the damage rate of the medium-efficiency exhaust fan box motor and ensures proper heat dissipation in the medium-efficiency air inlet fan box.
