The Function of Fan Filter Units (FFUs) and Their Critical Applications in Clean Environments
Created on 07.08
In modern industrial production, clean environments are crucial for product quality control. The Fan Filter Unit (FFU), as one of the core equipment for clean environment control, plays an irreplaceable role in numerous high-tech industries. This article provides a detailed introduction to the functional principles and technical features of FFUs, as well as the outstanding performance of our factory's FFU.
I. Core Functions and Working Principles of FFUs
The Fan Filter Unit is an integrated air purification device combining a fan and a high-efficiency filter. Its primary function is to provide clean air for specific areas through forced circulation and high-efficiency filtration. The working principle of an FFU can be summarized in three key steps:
Air Intake: The built-in high-efficiency centrifugal fan draws in ambient air from the top of the unit
High-Efficiency Filtration: The drawn air passes through HEPA or ULPA filters, removing particles larger than 0.3 microns
Uniform Air Supply: The filtered clean air is evenly discharged from the entire outlet surface at a stable velocity of 0.45m/s±20%
This operational mode can continuously maintain air cleanliness in clean spaces, effectively controlling microdust contamination and meeting the stringent requirements of various precision manufacturing and production processes.
II. Outstanding Technical Features of FFU
The FFU produced by our factory incorporates multiple advanced technologies and boasts the following prominent features:
1. High-Performance Fan System
Utilizes direct-drive high-efficiency centrifugal fan design with over 30,000 hours of operational life
Low-noise operation (≤62 dB) with vibration controlled below 0.08mm/s
Supports stepless speed regulation, maintaining stable airflow even with filter resistance changes
2. Modular Flexible Design
Can be used as a standalone unit or combined to form complete clean production lines
Particularly suitable for constructing Class 100 (ISO 5) cleanliness assembly lines
Modular connection design facilitates system expansion and layout adjustments
3. Premium Construction and Strict Quality Control
Body made of galvanized aluminum-zinc stainless steel, combining corrosion resistance with aesthetics
Unique air duct design optimizes airflow distribution, ensuring uniform air supply
Each unit undergoes strict testing according to US Federal Standard 209E before leaving the factory
III. Typical Application Scenarios for FFUs
The FFU, with its outstanding performance, can be widely applied in the following fields:
Semiconductor Manufacturing: Providing stable clean environments for chip production lines
Biopharmaceuticals: Meeting GMP requirements for sterile production environments
Precision Electronics: LCD panels, integrated circuits, and other precision manufacturing
Food and Pharmaceutical Packaging: Ensuring dust-free requirements in packaging processes
Laboratory Research: Providing clean spaces for sensitive experiments
