Fan Filter Unit


Fan Filter Unit (hereafter called FFU) is air clean equipment with fan built-in, which is usually put on the modular T-Grid. It has extensive

application in electronics and biological industries that require air clean environment.

1.It adopts AT fan with low noise and high efficiency which AIRTECH JAPAN especially designed for FFU. It has the feature of

energy-saving with low carbon, no maintenance, high reliability and long life.

2.Optimized capacity and distributaries guided whirl tube reduce the overall height and enhance the uniformity of air blow-out.

3.Large suitable interval of air velocity and volume (see the operating curve) can satisfy the requirements of different types of clean

environment. It is also suitable for use where high air velocity is required for Class A area of biology and pharmacy.

4.It adopts low resistivity filter that can provide 75-120Pa excess pressure outside the product under rated airflow, which meets the

need of high resistivity of return air in the clean room.

5.Multi-optional and flexible layout :

◆ Filter:  
Standard configuration: HEPA (H13、H14)  Optional: ULPA (U15、U16)
◆ Fan:   
Standard configuration: AT Fan DCBL motor Standard configuration: AT Fan AC motor
◆ Material of case:   
Standard configuration: Al-Zn coated steel sheet  Optional: SUS304 or SUS430
◆ Optional configuration: pre-filter, fault alarm, single stand outlet (with plug)
◆ Control mode of FFU is optional:
