FFU(fan filter units)Cleanroom Equipment

Core Functions and Working Principle:

The FFU (Fan Filter Unit) draws in air from the top, filters it through a pre-filter and a high-efficiency (or ultra-high-efficiency) filter, and then delivers clean air vertically downwards at a uniform airflow velocity of approximately 0.45 m/s ± 20%, forming a unidirectional laminar flow that effectively prevents contaminants from entering the work area. Its core function is to provide a continuous and stable supply of high-cleanliness air for cleanrooms, clean benches, and other microenvironments.

Main Structural Components:
* Enclosure: Typically made of stainless steel, galvanized sheet, aluminum-zinc coated sheet, or aluminum alloy, providing a robust and corrosion-resistant structure.
* Fan: The core power component, commonly an AC (alternating current) or DC brushless (EC) fan, driving airflow.
* Filtration System: Includes a pre-filter and a HEPA/ULPA main filter, achieving a filtration efficiency of over 99.97% for 0.3µm particles, with some reaching 99.999%.
* Deflectors and Flow Equalization System: Ensure uniform airflow velocity at the outlet surface, reducing dead zones.

Control unit: Supports multi-speed adjustment, stepless speed regulation or remote group control by computer, to achieve energy saving and intelligent management.

Application:

FFU fan filter units can be connected modularly. FFU fan filter units are widely used in clean rooms, clean operating tables, clean production lines, assembled clean rooms and local 100-level applications. FFU fan filter units can be used to make simple clean workbenches, clean sheds, clean transfer cabinets and clean storage cabinets.

Functions & Features:

Most FFU fan filter units are made of imported environmentally friendly aluminum-zinc plates, which will never rust, are corrosion-resistant, light and strong. The box body adopts the golden ratio point design. The FFU fan filter unit is beautiful and generous, with an ultra-thin body thickness of only 23cm, and a total thickness of no more than 30cm with a high-efficiency filter; the weight is only 24kg, which saves space, facilitates construction and installation and daily maintenance, and the FFU fan filter unit has obvious energy-saving effects, ultra-low noise, uniform wind pressure diffusion, uniform and stable wind speed on the air outlet, low power consumption and low operating costs, and a working life of more than 50,000 hours.
