Negative pressure fans have the advantages of low purchase price, low usage cost, and effective ventilation and temperature reduction

Negative pressure fans have become popular among pig farm users in recent years due to their low purchase price, low usage cost, good ventilation and cooling effect, long service life, no occupation of space, and simple installation and construction. Nowadays, the quality, style, specifications, and air volume parameters of negative pressure fans vary in the market, resulting in hundreds of different specifications and models. As a pig farm user, how to choose the suitable negative pressure fan specification and model for oneself? Today, I will share with you the selection of negative pressure fans.

1、 Select the specifications and models of the negative pressure fan based on the size of the location where the pig farm intends to install it:

The specifications and sizes of negative pressure fans vary, and there are many sizes to choose from. When used in pig farms, most of them need to be installed on windows and walls. In order to minimize the occupation and damage to the user's site, the selection time of negative pressure fans must be based on the reserved installation position to choose negative pressure fans of similar specifications and sizes.

This is the fiberglass negative pressure fan commonly used in pig farms

For example, if the reserved position for installing a negative pressure fan is 1 meter * 1 meter, then choose a negative pressure fan that is close to 1 meter * 1 meter. If you choose a negative pressure fan with a size that is too large, it will not be able to be installed. If you choose a negative pressure fan much smaller than this reserved size, it will cause the effect to not be achieved, and more need to be installed, resulting in large gaps after installation. It is recommended that our pig farms understand that the size of the location where the user installs the negative pressure fan determines the specification size of the negative pressure fan. The exhaust volume, power, etc. of a single negative pressure fan are closely related to the specification size. Therefore, it is best to choose a negative pressure fan that is close to the installation location size. If the installation location is large and the selected negative pressure fan is small, the exhaust effect will definitely be poor, and it is difficult to deal with water leakage by sealing. If the size of the negative pressure fan is much larger than the installation location size, the negative pressure fan will definitely not be installed.

The owner of a pig farm, don't be too troublesome. It is recommended that you use a ruler to accurately measure the size of the position where you will install the fan before purchasing, and take notes. When purchasing a negative pressure fan, you can tell the negative pressure fan sales personnel about the size of the installation position. Professional sales personnel will give you some advice and help you confirm again which specification of negative pressure fan is more suitable for you.

2、 Choose the type of negative pressure fan based on your budget:

Any product has both high and low prices, and negative pressure fan products are no exception. Setting aside counterfeit and inferior fake negative pressure fans, the prices of negative pressure fans from reputable manufacturers vary due to differences in materials, processes, specifications, configurations, etc. Generally speaking, the cost of fiberglass anti-corrosion negative pressure fans is higher than that of galvanized sheet metal negative pressure fans. For negative pressure fans of the same style series, large-sized negative pressure fans are definitely more expensive than small-sized ones, and the price of negative pressure fans with direct drive motors is definitely higher than that of belt driven negative pressure fans.

If there is enough investment budget, choose fiberglass anti-corrosion negative pressure fan, after all, fiberglass negative pressure fan is more durable than galvanized sheet negative pressure fan. If the current funds are not sufficient, choose galvanized sheet negative pressure fan, save as much as possible. Simply put, if the budget is sufficient, choose the right one; if the funds are tight, choose the cheap one.

3、 Choose based on the service life:

The negative pressure fan is installed outdoors and often needs to be exposed to wind and rain, which can lead to a certain service life. The galvanized sheet metal negative pressure fan will rust and corrode the outer frame after a period of use, usually lasting 3-5 years. The fiberglass anti-corrosion negative pressure fan is made of acid and alkali resistant fiberglass material, and the outer frame will never corrode or rust. It can be used for more than 30 years without human damage. If you plan to use it for a long time, choose the fiberglass anti-corrosion negative pressure fan.

4、 Choose the type of negative pressure fan based on the difficulty of maintenance:

Any type of electrical or mechanical equipment product has maintenance issues, and negative pressure fans inevitably have maintenance issues during use. Fiberglass anti-corrosion negative pressure fans basically use motors to directly drive the fan blades to rotate and produce exhaust. Maintenance during use is to clean dirt and dust, which is very easy. Galvanized sheet metal negative pressure fans

Basically, a motor is used through a pulley to drive the fan blades to rotate and generate exhaust. After a period of use, the belt ages and wears out, requiring frequent replacement and maintenance. The maintenance cost is also higher than that of fiberglass anti-corrosion negative pressure fans.

5、 Select the type of negative pressure fan based on the effect of the exhaust volume:

Under the same specifications and motor energy consumption, the exhaust volume of fiberglass anti-corrosion negative pressure fans is generally larger than that of galvanized sheet metal negative pressure fans. This is because the motor quality and fan blade exhaust angle of fiberglass anti-corrosion negative pressure fans are higher than those of galvanized sheet metal negative pressure fans. Generally, the motor of fiberglass negative pressure fans uses pure copper wire cold-rolled plate motors with high torque of 10 levels or above, and galvanized sheet metal negative pressure fans generally use ordinary motors with about 4 levels. Due to the development of technology and the progress of society, the negative pressure fan ventilation and cooling industry is constantly innovating new products. In order to ensure that the majority of pig farm users can choose the right negative pressure fan products for themselves, it is recommended that you tell the negative pressure fan manufacturer your actual situation before purchasing, so that the negative pressure fan manufacturer can recommend suitable products for you. As the saying goes, choosing the right product is twice the result with half the effort. This article hopes to help more pig farm users who want to use negative pressure fans.
