Product details
Removable FFU | Liquid Tank Sealed FFU Product Features
The bottom of the FFU separated by the filter adopts a special fixed component design, which can be easily operated by one person during assembly, disassembly, and replacement of the filter.
2. Adopting an efficient AC centrifugal fan, the average wind speed is increased by 25%, and it has a high overheat protection function, effectively reducing losses.
Stable wind speed and long service life. Suitable for cleanrooms with cleanliness levels of 1-1000.
4. It is particularly suitable for assembling into ultra clean production lines, which can be arranged as a unit according to process requirements, or connected in series to form a 100 level assembly line.
5. Unique liquid tank sealing method with PAO dust generation port and concentration sampling port, fully meeting the requirements of the new version of GMP-E. Lightweight and lightweight body, convenient for use in narrow spaces.
The full English name of FFU is (Fan Filter Unit), and the Chinese technical term is Fan Filter Unit. FFU fan filter units can be used in a modular manner. FFU is widely used in cleanrooms, clean workbenches, clean production lines, assembly cleanrooms, and local 100 level applications.
Traditional FFU filters are sealed under negative pressure, while high-efficiency filters are installed below the FFU box and sealed by the weight of the FFU box. If you want to replace the high-efficiency filter, you need to remove the FFU box. realization.
Separable FFU | FFU technology achieved through liquid tank sealing components:
Considering the above technical issues, the present invention designs a detachable high-efficiency filter FFU equipped with an FFU box. Place a high-efficiency filter for air filtration under the FFU enclosure and another high-efficiency filter under the FFU enclosure. The filter installation frame and the high-efficiency filter are fixed to the high-efficiency filter installation frame and installed, and the high-efficiency filter and the high-efficiency filter installation frame are detachably connected. Specifically, the installation process is carried out on the high-efficiency filter installation frame by setting a flange at the lower end of the high-efficiency filter, installing the flange during the installation process, and fixing the high-efficiency filter to the high-efficiency filter installation frame with screws.
2. In order to achieve the fixed installation of the FFU box, there are also winding keels around the FFU box for hanging the FFU box. One end of the winding keels is fixed to the top plate, and the other end is fixed to the FFU box. Fixed connection. Body.
In order to improve the sealing effect between the high-efficiency filter and the FFU box and enhance the air filtration effect, the upper end of the high-efficiency filter installation frame and the upper surface of the high-efficiency filter are placed on the same plane. The FFU box is very suitable.
4. In order to more accurately fix the high-efficiency filter mounting bracket and improve the sealing performance between the high-efficiency filter mounting brackets, please further bend the upper end of the high-efficiency filter mounting bracket inward at a right angle. Perform efficient filtering. Connect the side of the device.
5. Compared with the existing technology, the advantage of the present invention is that by installing the high-efficiency filter mounting frame under the FFU box, the weight of the FFU box is between the FFU box and the high-efficiency filter mounting bracket. It's through. To achieve negative pressure sealing, please screw the high-efficiency filter onto the installation frame of the high-efficiency filter and perform negative sealing on the exhaust port surfaces of the high-efficiency filter and FFU box. If you need to replace the high-efficiency filter, simply remove it. You can easily and quickly remove screws from the high-efficiency filter installation frame without disassembling and installing the FFU box.
6. The present invention relates to the field of filter FFU technology, particularly to a lower detachable high-efficiency filter FFU. Equipped with an FFU box, place a high-efficiency filter for air filtration under the FFU box, place a high-efficiency filter installation frame under the FFU box, and then fix and install the high-efficiency filter on the high-efficiency filter installation frame. It can be detachably connected to the installation frame of the high-efficiency filter. By installing the high-efficiency filter installation frame under the FFU box, the FFU box and high-efficiency filter installation frame will pass through.
7. Use the weight of the FFU box to achieve negative pressure sealing, screw the high-efficiency filter onto the installation frame of the high-efficiency filter, and perform negative sealing on the air outlet surfaces of the high-efficiency filter and FFU box. . The filter is convenient and easy to use, as it can be removed from the installation frame of the high-efficiency filter by simply removing the screws.
