Intelligent control with built-in fan filter unit PuriFan EC FFU
PuriFan EC FFU intelligent control with built-in fan filter unit has been widely used in places with extremely strict requirements for pollutants in the air, such as semiconductors, electronics, food, flat panel displays, biopharmaceuticals, etc. It is installed in turbulent and laminar flow clean rooms and can achieve high requirements of cleanliness levels 100, 10, and 1.
control system
Adopting the independently developed AIX-I control system, it can achieve large-scale networked centralized control while also enabling precise data reading and control of a single FFU. In addition to retaining the original functions of multi-level hierarchical management, alarm prompts, and schedule management, the system has added more user-friendly control modules such as intelligent partition management, intelligent display control, and intelligent reading to improve the convenience of later maintenance and use. High total static pressure value, using a high-pressure integrated fan, enables our FFU to provide an external static pressure of 50-150Pa under rated airflow. If a low resistance PTFE filter is selected, the external static pressure can be increased. An additional primary filter can be added.
Extremely low chemical gas dispersibility
To meet the needs of special industries, all constituent materials are made of low chemical gas dispersing materials and undergo strict testing. The filter can also use PTFE filters with lower chemical gas dispersibility.
Easy to install
The overall design is flexible, and according to the design specifications, it can be matched with any form of ceiling skeleton without the need for clamping devices. When the filter adopts a knife edge frame, the unit can also be used for liquid tank sealed ceiling skeleton.
Versatile optional accessories
Multiple optional accessories including inlet primary filter, outlet diffuser plate, differential pressure gauge, pressure online monitoring, Particle online monitoring, DOP test hole, inlet connection, indicator light, wind speed, temperature and humidity online monitoring, remote control, European standard plug, etc.
Low energy consumption
The brushless DC motor used is more energy-efficient than the AC motor. Compared to conventional AC FFUs equipped with fiberglass filters, EC FFUs can reduce energy consumption by 30% to 40%.
Unique structural design
The independently developed unique air duct structure design improves air uniformity by 5-8%, efficiency by about 5%, reduces noise by about 5DBA, and reduces vibration by about 20%. The overall efficiency of the machine can reach 58-60%, and the overall structural strength of the box is more solid.
.
.1. Compatibility: Traditional control systems in the market must run on Windows XP SP2 or Windows 7 Ultimate. And AIX-I can run on all versions of Windows, even future versions of Windows can use it.
2. Stability: AIX-I uses a new server management program. Simplify the connection between control software and servers on the basis of compatibility with existing databases. Thereby improving stability.
3. Fluency: Based on the CAD kernel design of C language, the software volume is greatly reduced, making the operating interface like AutoCAD, with flexible scaling and translation. Never distort. Thoroughly changing the graphics refresh jitter and clumsy scaling of traditional control systems. In addition, FFU box selection and multi selection have been added. Various alignment, translation, and so on.
The hardware of the new architecture from top to bottom is: server switch super gateway 1-FU.
Every 31 FFUs are connected as a group to the super gateway, and each super gateway can connect 8 groups. There are a total of 248 units. Each super gateway is connected to the switch. The maximum number of super gateways that can be used is 254.
8 ports are scanned simultaneously, so the scanning cycle of this system is 8 seconds.
Add many functions: FFU constant wind speed automatic adjustment. FFU work site streaming video surveillance.

The advantages of PuriFan EC FFU (current discharge function, effectively protecting the power grid system)
The advantages of PuriFan EC FFU (current discharge function, effectively protecting the power grid system)
Exe's EC FFU has a soft brake/soft start function, as shown in Figure 3. At the beginning, the fan was running in reverse at 970 revolutions per minute (250Pa external pressure). After the power is turned on, the fan enters the soft brake program. After 4.2 seconds, the reverse current is absorbed and the speed drops to 40 revolutions in reverse, achieving a soft landing of the speed. Then enter the soft start program, and after 12.2 seconds, the fan speed slowly increases to positive 1613 revolutions per minute, entering normal operation.
