What is FFU in Cleanroom? A Complete Guide to Fan Filter Units
Created on 07.07
Introduction
In cleanroom environments, maintaining a contaminant-free space is critical for industries like pharmaceuticals, electronics, biotechnology, and semiconductor manufacturing. One essential component that ensures clean air circulation is the Fan Filter Unit (FFU).
FFUs are self-contained air filtration systems that provide laminar airflow to maintain high cleanliness levels. In this blog, we’ll explore what FFUs are, how they work, their key features, and their applications in cleanrooms.
What is an FFU?
A Fan Filter Unit (FFU) is a modular air purification device that integrates a fan and a high-efficiency particulate air (HEPA) or ultra-low penetration air (ULPA) filter. It is designed to deliver uniform, filtered airflow to maintain ISO-classified cleanroom standards.
FFUs are commonly used in:
l Cleanrooms
l Clean workstations
l Modular cleanrooms
l Laminar flow hoods
l Assembly lines requiring high cleanliness levels
How Does an FFU Work?
The FFU operates by:
Drawing in air from the surrounding environment through the built-in fan.
Filtering the air through a HEPA or ULPA filter to remove particles as small as 0.3 microns with 99.999% efficiency.
Supplying clean air at a consistent velocity (typically 0.45 m/s ±20%) across the entire surface, ensuring laminar (unidirectional) airflow.
This process helps eliminate dust, microbes, and other contaminants, maintaining a controlled cleanroom environment.
Key Features of Our FFU (Model: FFU-GCC1000)
