It is equipped with photoelectric sensor, one-way channel air shower room, entering from the non clean area, infrared induction after closing the door, locking the door after the shower, and only going out of the shower room from the door; 2. Humanized operation: humanized control panel research and development, clear indicator light indication, giving users clear and correct wind shower process indication, soft key touch time relay, LED display and setting High efficiency filter with high efficiency and low resistance in the U.S.A. with high efficiency and low air cleaning time. 99% to ensure the purification level.
The single and double blowing shower room is installed between the clean room and the non clean room. When people want to enter the clean area, they need to go through a single and double blow shower. The clean air can remove the dust carried by people, which can effectively block or reduce the dust source from entering the clean area. The front and rear doors of the single person double air dryer are electronically interlocked, which can also play the air lock and function to prevent the raw air from entering the clean area.
1。 Box design of purification air shower: the box adopts modular design, which not only ensures the firmness and beauty of the whole machine, but also takes into account the convenience and rapidity of installation.
3。 Air supply system: adopt low-power, high-pressure, energy-saving high-quality fan, fully consider the customer's cost, in the case of ensuring product quality, save every cent of money for customers.
5。 Filtration system: the filtration system is composed of primary efficiency and high-efficiency two-stage filtration to ensure that the air shower can reach your required cleanliness.
FFU has the advantages of long working time, low noise, maintenance free, small vibration, stepless speed regulation, uniform wind speed and convenient installation. FFU can be used in modular connection, which makes FFU widely used in dust-free room, dust-free operation platform, dust-free manufacturing line, assembled dust-free room and local 100 class applications. FFU is equipped with primary and high efficiency two-stage filter screen.
It is found that the particle size is greater than or equal to 0. 5 μ m dust ≤ 3. 5 pieces / L ★ horizontal or vertical laminar flow ★ ultra thin high efficiency air filter without partition board is adopted, which takes up small space ★ touch type electronic control panel is adopted. The air volume of fan can be adjusted steplessly to ensure that the wind speed in the working area is always in the ideal state ★ stainless steel worktable, plexiglass enclosure, can be equipped with ultraviolet lamp, electrical interface application range ★ long term use in electronics and biology The operating environment with high cleanliness in precision instruments and other industries is a kind of local air purification equipment with strong public utility. FFU has a bright spot: flexibility. The operating environment with 100 cleanliness level is provided.
FFU (fan filter unit) is a combination of fan and filter, also known as "filter equipment with its own fan". The "FFU" is generally installed on the "dry" end of the frame. The upper part of FFU is fan module and the following part is filter. Single air shower
1。 It is composed of cabinet, stainless steel door (steel plate paint door or color steel plate door with window), coarse filter, high efficiency filter, fan, static pressure box, nozzle interlock controller, operation panel, induction device, etc. 2。 It is equipped with stainless steel door, stainless steel door and automatic sterilizing device.
2。 Control system: using microcomputer PLC control module to ensure the safety, stability and low failure rate of the system. With electronic interlock, adjustable air shower time, voice prompt and other functions.
The two doors of double air shower room are electronically interlocked, which can act as airlock and special features to prevent external pollution and unpurified air from entering the clean area. It is strictly forbidden for the staff to bring hair, dust and bacteria into the workshop, so as to meet the strict dust-free purification standard of the workplace and produce excellent products. The material of the air shower room is the common type, which adopts the "EPS" series of 50 mm thick sandwich color steel plate and supporting aluminum profiles. Its flash point is that the cost is low and the material is the same as that of the purification room, so the overall feeling is good.
1. Before entering the air shower room, please change clothes, wear clean clothes, and carefully observe the condition of the air shower room. When the red idle indicator light on the box is on, it means it can enter the shower. If the green indicator light is on, the air shower room is in working state. Please wait a moment. After the work of the air shower room is finished, the personnel in the room leave and the door is closed automatically. 2. Open the door of the air shower room and close the front door automatically after entering the room. Go straight through the photoelectric sensor and start the shower.

The function of stainless steel air shower room / ordinary air shower room / single air shower room / double air shower room: it can prevent external pollution and unpurified air from entering the clean area. To prevent the staff from bringing hair, dust and bacteria into the workshop, to meet the strict dust-free purification standards of the workplace, and to produce high-quality products?
Low micro vibration: the total vibration rate is less than 1 mm / s, and the amplitude is not more than 4? With low energy consumption and low heat dissipation, fan quality and dynamic balance design customization, as well as zero pressure loss of the box itself, the energy consumption and heat dissipation of Zhongzheng FFU under the same output conditions are lower than those of the first class products. Flexible control mode of single air shower in Rongchang: AC type can adopt single vertical governor or group variable pressure governor, and has alarm and indication function.
