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 Common Applications:
Standard 209E).
Conventional cleanroom construction
We developed FFU is from basing upon the concepts
Module hard and soft wall cleanrooms
including, to reduce running cost by saving energy, and to
Laminar flow cabinets and other clean air devices
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. Quality control at factory before shipment:
Our manufacturing capabilities range from complete Functional tests and visual inspection
computerized sheet metal design, to fabrication and Electrical safety analysis tests
assembly. A vertically-integrated approach ensures that Air velocity testing
quality can be controlled at every step of the way.

Blower Options:
Standard AC blower
Fan Filter Units utilize a standard AC Blower,
there are two options of blade as below:
Steel blade, the advantage of which include:
• Large air volume.
• Low power consumption
Plastic blade, the advantage of which include:
• Low noise level.
• Low power consumption
DC blower
Optional DC blower is available and has the
following advantages: `
• Low noise level.
• Low power consumption
• Low heat output
• Energy-efficiency
With DC blowers, 100’s of FFU’s may be
connected via a network to a single computer
system for centralized maintenance and remote
monitoring.
