When installing the negative pressure fan, the wall of the fan here must be treated with airtight. In particular, there can be no clearance around the fan. The ideal way to assemble the negative pressure fan is that the walls on one side of the fan and the surrounding Windows and doors are all closed, and the Windows and doors on the opposite wall of the fan are opened to ensure that the air flow is in a straight line.

The assembly of the negative pressure fan is a particularly key project. The actual effect of the use of the negative pressure fan in the future has a great impact. It must be paid attention to at all times in all links of the assembly.

Before the assembly

1. Before the assembly of the negative pressure fan, we should carefully check whether the negative pressure fan is intact, whether the fastener bolts are loose or fall off, and whether the impeller has knocked against the wind cover. Carefully check whether the fan blade or louver is deformed or damaged during transportation.

2. When selecting the air outlet environment for assembly, attention should be paid to the fact that there can be no large barrier within 2.5-3m directly opposite the air outlet.

When the assembly

1. Stable assembly: attention should be paid to the horizontal orientation of the negative pressure fan when it is assembled, and it should be adjusted to the level that the negative pressure fan is firm with the foundation plane. The motor should not be skewed after assembly.

2. When assembling the negative pressure fan, the control bolt of the motor should be located in the direction convenient for practical operation. In order to facilitate the use of the control belt tight loose.

3. When assembling the support frame of the negative pressure fan, make sure that the support frame is firmly horizontal with the ground plane. If necessary, assemble the Angle iron beside the negative pressure fan to take reinforcement.

4. After the assembly of the negative pressure fan, it is necessary to check the surrounding airtightness. If there is a gap, to use the sun plate or glass glue to take airtight.

After assembly

1. After the completion of assembly, check whether the inside of the negative pressure fan is left behind props and sundries. Rotate the fan blade by hand or lever to check whether it is too tight or brushed, and whether there is no guide that prevents the rotation of the object, before the test run can be taken.

2. If the vibration of the negative pressure fan or the abnormal sound of the "buzzing" of the motor is shown during operation, it should be shut down and checked, and then started for use after repair.
