Farming negative pressure fan

Characteristics of aquaculture negative pressure fans:
1. The outer frame is made of zinc, the thickness of the plate is 1.0mm, and the zinc layer is 275g'm2.
2, the fan blade is made of 66 type nylon mixed with 30% glass fiber, high hardness and toughness, through the dynamic flat street test, reducing energy consumption and increasing the service life.
3, 175 grams / square meter high zinc layer sheet, 0.6mm thick, easy to install and disassemble.
4. The belt is made of Japanese Samsung belt.
5. Motor: There are a variety of motors to choose from.

6, the opening method of the louver: no heavy hammer, can achieve natural opening and closing.
Detailed inspection of the cultured negative pressure fan before and after installation:
1. Carefully check that the fan is in good condition before installation. Do not install if the part is loose or falling off.
2. Check if there are any leftover tools and debris inside the fan after installation;
3. Whether the fan blades are too tight or have friction, and the omission should be eliminated before commissioning.
4. The adjusting bolts for the cultured negative pressure fan should be placed in a convenient position to adjust the tightness of the belt in the future. If equipped with a frequency converter, the fan switch should be operated normally according to the requirements of the inverter, so as not to affect the service life of the fan.
5. During the operation of the animal husbandry fan, if abnormal phenomena such as fan vibration or motor “嗡嗡” are found, stop the inspection or consult the seller in time, and eliminate the abnormal phenomenon before starting the machine.
6. Pay attention to keep the horizontal position of the fan and avoid tilting.
