PuriFan EC FFU

Product features

PuriFan EC FFU has been widely used in semiconductor, electronics, food, panel display, biopharmaceutical and other fields with extremely strict air contaminant requirements. It is installed in turbulence and laminar flow cleanroom, to meet the require-ments of Class 100, 10 and 1 classrooms.

Control system

The self-developed AIX-I control system is used to achieve large-scale networked centralized control, while also allowing accurate  data  reading  and  single  FFU  control. The  system  retains the  original  multi-layer  hierarchical  management,  alarm prompting, schedule management and other functions, and focuses on adding more humanized control modules such as intelli- gent partition management, intelligent display control and intelligent reading to improve usage and maintenance work.

Total high static pressure

The use of high-pressure integrated fan allows the FFU to provide 50~150Pa external static pressure under rated airflow, which can be increased by using a low-resistance PTFE filter. Additional primary-efficiency filters can be equipped.

Extremely low chemical gas dispersion

To meet the special industrial needs, all component materials are made of low chemical gas dispersal materials and are rigor-ously tested. PTFE filters with even lower chemical gas dispersion are also available.

Easy installation

The overall design is flexible and can befitted with any kind of ceiling framework without clamping device according to design specifications. The unit can also be used with gel seal ceiling framework when the filter has a knife-edge frame.

Multi-function optional accessories

The  optional  accessories  include  air-inlet  primary-efficiency  filter,  air-outlet  diffuser,  differential  pressure  gauge,  online pressure monitor, online particle monitor, DOP test hole, air-inlet tube, indicator, anemometer, online temperature and humidity monitor, remote control, European standard connector, etc.

Low energy consumption

The brushless DC motor is more energy-saving than AC motor. Compared with the conventional AC FFU equipped with glass fiber filter, EC FFU can reduce energy consumption by 30% ~ 40%.

Unique structure design

The unique air duct structure design can improve the air outlet uniformity by 5-8%, increase efficiency by about 5%, reduce noise by about 5DBA, and reduce vibration by about 20%, reaching an overall efficiency of up to 58-60% and stronger overall structural cabinet strength.

Advantages of PuriFan EC FFU

(gradual current discharge function, effectively protecting the power grid system)

Figure 1 shows the diagram of the startup current of common AC FFUs and some domestic DC FFUs. Within 2.5 seconds after startup, a very large inrush current is generated, which  is  usually  3.5  times  of the  running current, causing a great impact on the power grid and power switching system.

AIX's EC FFU adopts high-quality DC motor fan with gradual current discharge function. The current gradu- ally increases within 12 seconds after the FFU starts and finally  reaches  the  running  current,  thus  effectively protecting the power grid and power switching system, as shown in Figure 2.

Manual control

TKSAGE's EC FFU has powerful functions. It can realize the start, stop and speed setting of single FFU and group FFU as well as the FFU fault detection, and it can also realize the control of gateway.

With  a  full-Chinese  menu,  the  device  is  easy  to  operate.  It  is  also equipped with high-performance lithium battery, so it can work continuous-ly for 20 hours and can be charged via USB.

Tablet group control

1. The DC tablet group control system is suitable for multi-room separate control or small clean workshop field control.

2.  The  control  system  consists  of  the  tablet,  signal  collector,  signal amplifier (no amplifier for less than 31 FFUs), and FFU, with the response time of less than 1s.

3. Each amplifier can connect up to 31 FFUs, and the system can connect up to 255 amplifiers to control maximum 7905 FFUs.

Intelligent control system AIX-1

AIX-I is a hierarchical control system that resides on a public infrastructure network based on open system standards, allowing seamless integra-tion and interoperability. It is a control system specially developed for the remote centralized control of super large FFUs in large clean workshops, with comprehensive access control and many other functions, it is suitable for large and medium-sized enterprises.

The PuriFan EC FFUs/EFUs realize link control of the remote control terminal (PC) through the Super Gateway.

Each Super Gateway can control 8 groups of FFU/EFU, totaling 248 units, and one PC can link 254 Super Gateways through the switch to control a maximum of 62992 FFUs/EFUs. The server can receive data from all the Super Gateways every 8s, and the response speed of the whole control system is tens of times faster than other ordinary control systems.

●1. Compatibility: The traditional control systems must run on Windows XP SP2 or Window 7 flagship version, while AIX-I can run on all versions of Windows, even future versions.

2. Stability: AIX-I uses a new server management program, which is compatible with the original database and simplifies the connection between the control software and the server, thus improving the stability.

3. Fluency: By adopting the CAD kernel design based on C language, the software volume is greatly reduced, so that the operation interface can scale and pan freely like AutoCAD, without distortion. This design completely changes the jittered graphics refresh and clumsy scaling of traditional control systems. Besides, the system is multiple FFU options, including alignment and translation.

●The hardware of the new architecture is, from top to bottom: Server - Switch - Super Gateway - FFU.

●Every 31 FFUs are connected to the Super Gateway as a group, and each Super Gateway can connect 8 groups, totaling 248 FFUs. Each Super Gateway is connected to a switch, which can connect to up to 254 Super Gateways.

●8 ports can be scanned simultaneously, so the scan period of this system is 8s.

●Many functions are added, such as FFU constant air speed automatic adjustment, and FFU work site streaming video surveillance.
