I. FFU (AC):
FFU is abbreviated as Fan Filter Units, which means "Fan Filtration Unit" in Chinese. Exactly is a self-powered, modular end air supply device with filtration effect. Fans from the top of the FFU will be air inhalation and HEPA filtration, after filtering the clean air in the entire air surface to 0.45m / s ± 20% of the wind speed uniformly sent out. FFU can be modularized to connect the use of the FFU, so that the FFU is widely used in the clean room, dust-free operating table, dust-free production line, assembled dust-free room and local class 100 applications.
The FFUs produced by Landmark can be divided into AC (alternating current) FFUs and EC (direct current) FFUs according to the motors, and can be divided into cold plate spraying, aluminum-zinc plated plate, 201/304 stainless steel and aviation aluminum plate according to the materials of the box. Modular centralized group control management, the use of computer control systems, can be distributed in different workshop floors of the FFU, centralized start-stop, speed timing, easy to operate, saving resources.
FFU Features:
1, FFU box body can choose stainless steel, aluminum zinc plate, cold plate electrostatic spraying, aviation aluminum plate made of beautiful and generous.
2, FFU box and high-efficiency filters using split design, installation and replacement of high-efficiency more convenient.
3, FFU fan using German imported EBM fan or domestic high-quality fan, the working time of up to 60,000 hours or more.
4, FFU adopts unique air duct design, the whole air outlet surface to 0.45M / S wind speed uniform delivery.
5, FFU has energy-saving, centralized computer control, stable operation, low noise, digital adjustment and other characteristics.
6, FFU according to the needs of the process can be used as a single unit, can also be more than one in series to form a 100-level assembly line.
7, the new FFU with liquid tank high-efficiency filters, more to ensure the sealing performance of high-demanding occasions.
8, FFU assembly fan performance is stable, low noise, low vibration, stepless speed regulation and other characteristics.

II. FFU (DC)
DC inverter FFU characteristics
DC inverter (FFU) fan filter unit, with low noise, large air volume, high net pressure characteristics, greatly reducing the cost, easy to install and maintain, is the ideal component of the clean environment.FFU can be modularized to connect the use of the FFU is widely used in clean rooms, dust-free operating stations, dust-free production lines, assembled clean rooms and local applications such as class 100.
Take our DC (EC) FFU1175X575 as an example, its air volume in 0.45m/s operation, speed regulation in 995r/m or so, at this time our EC FFU1175X575 energy consumption is 120W. and the use of AC AC FFU1175X575, its power consumption is 200W. 500 sets of FFU project as an example to compare....
1. Taiwan energy consumption ratio: 200W-120W = 80W / Taiwan / hour (power savings);
2.1 a day to save power: 80W / Taiwan × 24 hours / 1000 = 1.92 degrees / day / Taiwan
3.one year power savings: 1.92 degrees x 365 days = 700.8 degrees / year / unit
4.500 units a year to save electricity: 700.8 degrees × 500 units = 350400 degrees / year
5. According to the average price of electricity 1.2 yuan / degree calculated savings: 350400X1.2 = 420,480 yuan / year;
EC fan FFU with AC fan FFU compared to more investment of 1100 yuan per unit, 500 units of total investment of 550,000 yuan. From the above 500 units a year to save electricity counting , 424,480,000 yuan -550,000 yuan = -129,530,000 yuan, 15 months to recover all the more than the increased investment, 15 months after the savings in electricity can be considered to be the company's net income.
In summary, with 500 sets of FFU life span of 10 years as a limit: DC FFU can save the company: 420480X10-550000=3654800 yuan. DC FFU is the trend of future development.
