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.
