The PMSM Fan is a new type of high-efficiency and energy-saving ventilation equipment. It uses permanent magnet frequency conversion technology to achieve precise control of the fan speed, and has the characteristics of high efficiency, silence, and environmental protection. It is favored by more and more enterprises and consumers. favor.

Generally speaking, the frequency of safety inspections of CorTec hvls fan mainly depends on their frequency of use. Under normal circumstances, it is recommended to check once or twice a year to check whether the boom, screws, blades and other components of the industrial fan are loose, and whether there are cracks, deformation, corrosion and other abnormalities.

Recently, a piece of news that "sudden power outage at night in the pig farm, 462 pigs died of heat and lost millions?" made headlines. The news said that due to the high temperature in summer, the ventilation fan of the farm suddenly failed due to a power outage, resulting in poor ventilation in the farm, and nearly 100 pigs died of suffocation due to lack of oxygen. Similar incidents occurred in Suizhou, Hubei and Nantong, Jiangsu.

Ventilation problems in logistics warehousing may include the following aspects:
1. Poor air circulation: Logistics warehousing usually stacks a large number of goods, and the gaps between the goods are small, resulting in poor air circulation and difficult to maintain a good ventilation effect.
