Fan filter unit (FFU), aslo known as laminar flow module, fan-powered filter, is a type of air filtration device that can remove contaminants from the air and make the air more clean up to ISO-5 (Class-100). It typically consists of a fan, a HEPA filter, and a motorized impeller, all housed in a compact, self-contained unit.
Fan filter units are normally applicable to various cleanrooms, big or small. The type of small-area application is the soft-wall cleanroom. By using different quantity of FFUs, the soft-wall cleanroom can acheive different air cleanliness class arranging from ISO-4 (Class/10) to ISO-8 (Class-100,000).
Features:
- Applicable to the areas which require the air cleanliness ranging from ISO4 to ISO8 (Class10-100,000)
- Casing can be aluminized zinc plate or stainless-steel plate
- Average airflow output, stable running state
- 3-gear or stepless speed regulation
