Used in clean room from class 100,000 to 10,FFU provides clean air as well as particle filtering controlling - details see: https://www.machineto.com/clean-room-ffu-clean-room-fan-filter-unit-10248040

FFUis short forFan Filter Unit, the fan of which intakes the air from the top of FFU and the air is passing through HEPA Air Filters, and then the clean air is sent out, is the end air supply with filtering units that have power with themselves. These series can be used in modules.

FFUprovides clean air as well as particle filtering controlling. These series, the general dimensions of which are 2×4 and 4×4 inches, are often installed on the ceiling of clean rooms.

Application: Used in clean rooms ranging from class 100,000 to 10, they can come into being ultra-clean assembly line, clean work office, clean booth, clean closet and etc...

• Nice appearance , human centered design--Adding stainless handle, easy installation and delivery, and perpendicular design.
• High performance and low noise fans--Adopting Energy-saving Multi-blade turbine fan, low noise, Pressure spreads evenly, stable air velocity, low consumption, low running cost, service life can reach to longer than 80 thousand hours.
• Light, thin shape--Without filter net, thickness of shape is 23cm, 25KG weight, application in low ceiling are also available.
• Flexible, diversified design--Except for standard items, custom made FFU is available, such changings as filter nets, the materials of shell and etc...
• Concerning, convenient design---Pedals are designed in the body, which makes it convenient to install and repair.
