>FFU (Fan Filter Unit)

Definition: FFU is the simplest purifying equipment consisting of fan and HEPA filter, and the most basic type in air purifying equipment.

ISO qualification


Operation principle: Due to the one-to-one correspondence between HEPA filter and fan, a negative pressure area is formed outside the unit case to enable negative pressure sealing function. FFU may be used separately or in combination to achieve higher cleanness easily.

Applications: Micro-electronics, electronics, optics, bioengineering and other industries.


Advantages:

1 . FFU box with a compact structure and beautiful appearance.

2 . Long lifetime,lower noise,free maintenance,small vibration and can be used in combination.

3 . There is air guiding system inside the air tunnel which can lower the noise and improve the efficiency of the fan.

4 . Suitable for assembling to a purification line with HEPA filter which has a easier replacement.

5 . Use dust particle counter to test the unit one by one before shipment to ensure the quality.
