　　In recent years, the negative pressure fan has been favored by many breeding customers for its remarkable natural ventilation effect, long service life, simple installation, low cost and other advantages. Now the main parameters of negative pressure fan in the market are different, such as quality, style, specification and model, and exhaust air volume, which makes the model and specification of negative pressure fan reach hundreds. As a farm, how should I choose the model and specification of the negative pressure fan suitable for my own use?

　　Select according to the composition of exhaust steam body

　　Before selecting the model and specification of the negative pressure fan, we must consider clearly what problems we want to solve when buying the negative pressure fan, and scientifically study whether the gas composition in the exhaust environment has sustained high temperature, oil stains, inflammables and explosives, corrosion, etc. Only by making clear what is the composition of the natural environment steam, can we determine what kind of negative pressure fan is suitable for our own application. At present, there are three key materials for manufacturing negative pressure fans in the market: negative pressure fans made of glass fiber reinforced plastics, negative pressure fans made of galvanized sheet metal and anti-corrosion negative pressure fans made of 304 stainless steel. If there is strong acid and alkali corrosion in the gas composition of the exhaust, we must choose the negative pressure fan made of FRP or 304 stainless steel plate anti-corrosion materials. If exhaust gas temperature is not too high and there is no corrosion, negative pressure fan made of galvanized sheet material can be selected. Nitrogen dioxide in the breeding plant is generally heavy, and nitrogen dioxide has corrosion, so it is best to choose anti-corrosion materials for the centrifugal fans in the breeding plant.

　　Size selection according to pre installation position

　　Most negative pressure fans are assembled on doors, windows and walls. As the damage to the customer's site is reduced, the embedded assembly part must be consistent with the specification, model and size of the negative pressure fan. The size of the part where the customer assembles the negative pressure fan determines the specification, model and size of the negative pressure fan. As far as possible, the negative pressure fan close to the installation position and size shall be selected for the exhaust air volume and output power of the single strong fan. If the installation position is very large, the selected negative pressure fan is not large, the actual effect of ventilation is undoubtedly not very good, and it is difficult to solve the problem of water leakage by making sealing to prevent precipitation. If the size of the negative pressure fan exceeds the size of the installation position, there is no doubt that the negative pressure fan cannot be assembled. Therefore, before purchase, it is necessary to accurately measure the dimensions of the parts where the centrifugal fan is assembled and take notes. When purchasing a negative pressure fan, the salesman can be informed of the size of the installation position, and the appropriate negative pressure fan can be selected according to the salesman's proposal.

　　Select according to your own expense budget

　　All goods are priced, so is the negative pressure fan. It goes without saying that the counterfeit negative pressure fans of fake and shoddy products depend on the negative pressure fans of famous brands in large-scale factories. Because the materials, processing technology, specifications and models, equipment, etc. are different, the price of negative pressure fans is also different. Generally speaking, the cost of anti-corrosion negative pressure fan is higher than that of galvanized sheet metal negative pressure fan; For the negative pressure fans of the same style series, the prices of large-scale models are more expensive than those of small-scale models; The price of negative pressure fan with direct drive motor transmission is higher than that with belt transmission. If there is sufficient cost budget, choose 304 stainless steel plate negative pressure fan. After all, 304 stainless steel plate negative pressure fan is more durable than galvanized plate negative pressure fan. If the current assets are not sufficient, we will choose the galvanized sheet negative pressure fan. To put it simply, those with sufficient cost budgets should be selected, and those with low prices should be selected for those with insufficient funds.

　　Select according to service life

　　When the negative pressure fan is assembled outdoors, it is often exposed to the sun and rain, resulting in a service life. The frame of the galvanized sheet metal negative pressure fan will be corroded after being used for a period of time, which is generally available for three to five years. Glass fiber reinforced plastic anti-corrosion and 304 stainless steel plate negative pressure fans are made of corrosion-resistant raw materials. The frame will never rot and rust. The non-human damage can be used for about 30 years. If it is to be used for a long time, the FRP anti-corrosion or 304 stainless steel plate anti-corrosion pressure fan shall be selected.

　　Select according to the maintenance difficulty

　　All kinds of household appliances and industrial equipment have the condition of maintenance, and it is difficult to avoid this problem when the negative pressure fan is used. Basically, the glass fiber reinforced plastic negative pressure fan uses the motor to immediately drive the fan blades to rotate to cause exhaust. During use, maintenance is to clean up dirt and dust, which is very easy. The negative pressure fan made of galvanized sheet metal materials basically uses a motor to drive the fan blades to rotate according to the belt pulley, resulting in exhaust. After a period of application, the drive belt is aging and damaged, so the belt must be replaced frequently. The maintenance is inconvenient, and the cost of maintenance is also higher than that of FRP negative pressure fan.

　　Select according to exhaust air volume and actual effect

　　Under the condition of the same specification, model and size, and the same motor energy consumption, the exhaust air volume of FRP negative pressure fan is basically larger than that of galvanized sheet metal negative pressure fan, because the motor quality and fan blade exhaust angle of FRP negative pressure fan are higher than that of galvanized sheet metal negative pressure fan. The motors of general FRP anti-corrosion negative pressure fans are pure copper wire cold-rolled steel sheet motors with high torque above level 10, and the negative pressure fans of galvanized sheet metal materials are basically General Motors with level 4 above and below.
