Fan Filter Unit FFU mainly by the cabinet, centrifugal fans, high efficiency filter, operating switches, and other major components. Box with high-quality cold-rolled steel paint, with a compact, easy installation, low noise advantages; FFU Fan filter unit also features adjustable air volume fan system, by adjusting the fan operating conditions, can clean workspace average wind speed to maintain the rated range, and effectively extend the service life of high efficiency filter. 

 FFU works 
 Ambient air through the pre-filter, the centrifugal fan pressure into static pressure box, and then filtered through high efficiency filter surface from the wind blowing, the formation of clean air, clean air flow velocity through a uniform cross-section area needs cleaning, the area the dust away, to form the high cleanliness of work environment, as angle diffuser to increase and expand the scope of purification, can also be set in the outlet diffuser. 

 FFU fan filter unit features: ` 
 1, compact structure, easy installation, low noise, light weight, beautiful appearance and so on. 
 2, using a dedicated fan, long life, maintenance-free. 
 3, using a special flow channel and flow systems are designed with low noise, wind speed and uniform characteristics. 
 4, light weight, modular installation, the installation, replacement filters and maintenance more convenient. 
 5, flexibility. Because FFU are built momentum, it is not too many restrictions on the region, according to production needs, sub-control, group control and the remote computer to achieve function. 
 6, shorten the construction period. Using FFU to reduce the production and installation of air duct share a lot of time. 
 7, FFU to reduce operating costs. Operation and maintenance of FFU in the latter part of the simple and convenient; can be sub-control management, energy, real advocates of low-carbon technology to meet current requirements.
