一.How to install FFU?
FFU fan filter unit is generally how to install, how to install (graphic description)

FFUinstallation:
1.When installed in the clean room FFU, which shall be in the closed state, air-conditioning and clean fresh air delivery takes three days, and keep it clean of the room, so that no dust, all the keel are installed and leveled.
2.Each installer is recommended for 6 people, all personnel must wear clean clothes, clean gloves to prevent contamination of the artificially high efficiency filters or FFU.

1,When you are ready to install the required tools to use, as shown below, two installers in advance boarded ceiling, lay the metal assembly, foot keel, hands held onto the suspended truss; two installers to put on FFU on the table, and the high efficiency filter in the side ready.
2,Two staff leaning on aluminum ladder, carried to the fan unit to the ceiling, at the state level by 2 for the installation personnel collusion ceiling.
3,The ffu (fan filter unit) is inclined to send the two to catch ceiling installer
4,Two installers ceiling-light FFU, to prevent break something
5,In the clean room, carrying two HEPA filters filter installation personnel handed over to the two outer two officers, and they are attached to the filter
6,Two persons on the ceiling of the ffu up, and two staff members cleanroom stepping on the table to hit the ramp filter is transmitted to the keel (high efficiency filter should be in the direction of the windward side), since the high efficiency filter cartridge is very fragile, vulnerable, so the installation process can only transfer clenched its borders, gently, can not touch the inside of the filter, determined to avoid a collision filter.
7,The high efficiency filter installed horizontally so that the keel and allowed to bind.
8,Down FFU, the fan unit close to the high efficiency filter away, and installation have to be cautious to prevent damage to the filter. After installation, you must check whether all the pressure on the FFU high efficiency filter, is uniform, tightly. The installation is complete
二．FFU price?
For FFU and related products for, FFU prices take between 500-5000.
The main factors affecting the price has：
1、FFU material. FFU three materials are aluminum zinc plate, cold plate electrostatic, stainless steel, 304 stainless steel price is slightly expensive.
2、FFU fan. Because the fans are FFU of power is directly related to the whole operation of FFU.
3、FFU production process. FFU cabinet is working fine appearance, whether the work of running the noise impact of the production process of these FFU price.   
4、FFU filter. The quality of the filter purification efficiency in respect of FFU.
5、Manufacturers choice. FFU scale manufacturers, service and marketing will affect the price of FFU.
三，  What factors should be noted that the choice of FFU

1、Look fan selection, fan is the core component of FFU, to see whether big fan of the brand manufacturers export, and then to see whether the fan has done balancing measure；    
2、Look duct design, duct design is reasonable is the second factor in determining the amount of wind size Other FFU fan outside if it is turbocharged duct design, air flow and wind speed will be greater than ordinary graphic design duct;
3、Listen to the noise, allowing manufacturers to provide FFU prototype, test, listen to the noise level, even if the low noise and the noise can be accepted, if not uniform noise, the fan will be problems as soon as possible；  
4、Look designs and plate wall thickness, generally the main choice of the current mainstream FFU aluminum and galvanized sheet steel, a few steel spray. Material thickness at least between 1.0-1.2mm, if too thin, first, affect the quality of the second noise will be relatively large. This also may be feeling by Dian Dian weight.
 
四，FFU works
The use of FFU fan filter unit internal fan (motor + impeller) air (wind) inhalation, the absorption of air (wind) through FFU below HEPA (high efficiency particulate air filter) or ULPA (ULPA) filters, will fine particles of dust in the air filter out large particles, and finally the fresh air to 0.45m / s & plusmn; 10% of the velocity uniformity to the clean room. Can be used ffu clean room in general, they are more than one thousand in the cleanliness level. The basic structure is the first air through MAU (first filter, junior high efficiency filter) into the top of the clean room, and through the FFU (secondary filter, HEPA or ULPA) will be sent to clean indoor air, sent down by the wind raised floor and then into the return air box to the top of the clean room.

五，FFU features：
1、Beautiful appearance, user-friendly design. Installation of stainless steel handle, easy handling installation, rounded corner design, no indentation bending. 
2、Lightweight, thin body. Without filter, the body thickness of only 23cm, weighing only 25KG, a reduced ceiling spaces can adapt. Current optimized internal design. 
3、Thoughtful, designed with ease of installation design pedal, so that the body installation, easier maintenance. 
4、Flexible, diversified design. In addition to several fan filter criteria, the customer demand, production of different specifications of non-standard products. Such as: the type of filter, bulk material changes. Versatile options, optional air inlet filter initial efficiency, air inlet takeover, remote control, differential pressure gauge and other options. 
5、Multiple security. Touch control panel, without mechanical key switch, one-touch sensors, safe and reliable, overcurrent, overvoltage, overheating protection. 
6、Ensure uniform baking speed deviation is less than±10%. 
7、High efficiency, low noise turbofan. High efficiency, low noise, a unique patented technology. 
8、High-performance low-noise fan. Multi-wing turbine energy-saving fan, low noise, air pressure spread evenly, the surface wind speed is uniform and stable, low power consumption, operating costs, operating life of up to 60,000 hours.   
六，FFU role
FFU for the end device clean project. For air filtration, namely with the fan filter unit. Fans from the FFU at the top and air intake through HEPA (ULPA) filters, filtered clean air at the outlet side to 0.45m / s & plusmn; 10% of the wind speed uniform sent.
FFU can deliver high-quality clean room air. Industries which are widely used in the photovoltaic industry, precision electronics, liquid crystal glass, semiconductor, biopharmaceutical, mainly in a clean room, clean bench, clean production, the assembly type clean room and the local one hundred other occasions, and it has the air strict pollution control requirements where low energy consumption, lower operating costs.
