The world's first industrial fan was created by MacroAir. As a leading enterprise in industrial fans, MacroAir has cooperated with companies such as Coca-Cola, FedEx, IKEA, Walmart, etc., and is also the exclusive supplier of BMW, Chrysler, Ford, General Motors, Lexus, Mercedes-Benz, Nissan, etc. Its industrial fans are assembled in the United States and installed globally, the main markets are concentrated in the United States, Canada and other places, and the Asian regional market mainly involves Southeast Asia, India, etc., and has not yet established a stable market channel in China.
Although MacroAir is the manufacturer of the first industrial large fan, it has not been able to maintain its leading edge in the development, and it is inferior to Biaifeng in terms of product quantity, application field and product form. MacroAir's fans are not involved in the residential sector, mainly focused on industrial and commercial use, and all products are ceiling-mounted, which cannot meet the installation needs of different places like Biaifeng.
As the first in the industry, MacroAir naturally has excellent technology. Its products have UL certification and compliance in the United StatesNFPAStandard. The strength of the product lies in the control system and fan blades. In terms of control system, the controller independently developed by MacroAir - MacroAir Controller 30 realizes fan reverse reversal and automatic control management, can control up to 30 fans at the same time, and then cooperate with its AirEffect system to carry out temperature control, the principle is to measure the heat index by measuring the temperature and humidity of the ceiling and floor, and then take the heat index to calculate the ideal operating speed and direction of each fan, so as to run the fan. This is also the high-end technology in the industry. In the case of fan blades, the company has obtained a patent for a safety system for interlocking blades.
In terms of industrial use, MacroAir launched the X, Y, and Z series in the early days, and later introduced the AirVolution-D 780 and AirVolution-D 3 series. Each series of X, Y, and Z is complete in size, and the noise is slightly larger, 58-61 decibels. Among them, the X series with permanent magnet synchronous motors is suitable for harsh industrial environments, with an IP of 65 and a coverage area of 2044m², ranking first among MacroAir products. The Y and Z series have the same coverage area and an IP of 55, making them suitable for use in common industrial environments.
The AirVolution-D 780 and AirVolution-D 3 series feature improvements in motor, fan blade size, and noise. The previous products were mainly conventional geared motors, and both of them used permanent magnet synchronous motors. In terms of blade size, the AirVolution-D 780 is designed for tall spaces, while the AirVolution-D 3 is suitable for medium to large industrial spaces. The noise of both models has decreased compared to the previous series, and the AirVolution-D 3 is the most obvious, with a maximum specification of 7.3m fan noise decibels of only 56.
Not all new changes to the product will lead to product performance upgrades. The AirVolution-D 3 series becomes a three-leaf fan, while the other products are six-leaf fans. Although the three-blade fan design reduces weight, friction and raw materials, it can reduce the pressure on the building. However, the efficiency of the fan blades is also affected. In the same machine and 7.3m size fan, the AirVolution-D 780 covers an area of 2044m², while the AirVolution-D 3 is 1579m². It has been proven that without additional improvements to the performance technology of the fan blades, simply reducing the number of fan blades will reduce the coverage area, which in turn will affect the ventilation and cooling effect.
Commercial fans are ceiling fan type, and there are only two series, namely AirVolution-D 370 and AirVolution-D 550. The former is suitable for small commercial establishments, while the latter is suitable for medium and large commercial spaces. The AirVolution-D 550 series is also more high-end than the AirVolution-D 370, which is reflected in the fact that the motor is an industrial electronic drive jointly developed by Schneider Electric - Guardian Drive, which is industrial-grade circuit protection and can withstand voltage fluctuations in harsh environments. And the patented interlocking safety system prevents the safe connection between the fan blades and the hub under extreme conditions.
In terms of warranty, all MacroAir products are covered by a lifetime warranty for mechanical parts, while electrical parts are different, ranging from 5 to 7 years, depending on the product series model. Since MacroAir does not have a sales channel in China, if you want to buy MacroAir products, you can visit the official website to enter the online mall to purchase, but it needs to be transferred, and the subsequent installation and after-sales are not convenient. The installation height of the MacroAir industrial ceiling fan is more than 4.3 meters, and the suitable roof structures include I-beams, glulam beams and other structures.
