FAN FILTER UNIT (FFU)


Product Description

Fan Filter Unit is a self-contained ceiling unit for use in turbulent mixing and laminar flow cleanroom applications. Fan Filter Unit is designed to provide filtered laminar airflow over a specific area. The unit integrates a high efficiency fan together a HEPA/ULPA filter. The FFU draws in contaminated air from the top of the module, and exhaust filtered clean air vertically in a laminar air stream at its base. FFU’s are commonly used in the construction of Class 1 to Class 100,000 cleanrooms ( as per the US Federal Standard 209E)

We developed FFU is from basing upon the concepts including, to reduce running cost by saving energy, and to reduce initial cost by total design of clean room; such as noise specification etc, to meet all the requirements for constructing, operating, and maintaining cleanrooms. Our manufacturing capabilities range from complete computerized sheet metal design, to fabrication and assembly. A vertically-integrated approach ensures that quality can be controlled at every step of the way.


Product Characteristics

• Permanently lubricated, direct-drive centrifugal blower.

• Light weight, corrosion-resistant construction

• Wide range of ceiling grid system compatible

• Integral metal faceguard protects the HEPA/ULPA filter from damage during installation and transportation.

• Fan inlet guard grille ensure operator safety during installation and prevents large objects from falling into the casing and damaging the blower

• Pre Filter available on request

• Unique modular one-piece blower and electrical assembly is designed be serviceable and easily replaceable at lower maintenance costs.

• Standard unit shipped with 3 core electrical wires.

• Quiet operation of less than 56dBA (measured at a distance of 1m from the unit at the standard airflow velocity of 0.45m/s or 90 FPM with standard AC blower.)

• Choose from conventional AC or energy efficient EC Blowers Standard blower speed controller.

• Duct Collar 10” (250 mm) and 12” (300 mm): allows direct connection to the air air conditioning supply.

• Room-Side Replacement (RSR) available with gel seal filter element, filter is replacement from the roomside.
