Technical parameters and quality requirements:

• Modeling requirements: the overall modeling should be smooth, continuous, burr-free, damage-free and odorless.

• Filtration efficiency: it should be characterized by high filtration efficiency, good air permeability and easy cleaning.

• Air volume and noise: it should be characterized by high air volume, low noise, low energy consumption and low maintenance cost.

• Safety and reliability: it should be characterized by fireproof, explosion-proof, corrosion-proof and stable electrical performance.

Inspection before installation: 

• whether it is damaged or deformed due to packaging and transportation, and installation can only be carried out after it is properly repaired.

• Precautions during installation: the weight of the pipeline connecting the air outlet should not be borne by the ventilation tube, and it should be supported additionally during installation.

• Inspection before use after long-term idleness: If the fan is reused after long-term idleness, it is necessary to check whether the connecting parts are reliable and firm first, and then it can be officially used after trial operation.

• Regular inspection and maintenance: pay attention to whether there is abnormal noise in the operation of the ventilation tube, and check and repair it in time.

• Regular replacement of lubricating oil: besides replacing the lubricating oil after each overhaul, it is also necessary to regularly inspect and replace the lubricating oil.
