Product Description

The Fan Filter Unit (FFU) is specialized air cleaning equipment designed to supply purified air to clean rooms for manufacturing semiconductors, liquid crystals, and other precision electronics. Installed within the system ceiling grid, large clean rooms may require from several hundred to several thousand FFU units to maintain atmospheric integrity.

Key Advantages:

Simple direct speed control for precise airflow management.
Low power consumption ensuring energy-efficient operation.
Reduced sound power level for quieter working environments.
EC Fan with high reserve capacity for pre- and AMC filtration.
Ultra-low design height for space-saving installation.
Supports cleanliness levels from Class 10 to Class 1000.

Application & Usage

FFUs provide a flexible and economical modular solution for equipping turbulent clean rooms from ISO 8 to ISO 1. They are ideal for environments with minimal space above the false ceiling. Common applications include semiconductor manufacturing, electronics, flat-panel displays, disc-drive production, optics, bio-engineering, clean benches, and laminar flow hoods.

Frequently Asked Questions (FAQ)

Q1: What is the main function of a Fan Filter Unit (FFU)? A: An FFU is a self-contained fan and filter module used to supply purified, laminar air to cleanrooms. It draws in contaminated air from the top and exhausts filtered clean air vertically.

Q2: What materials are available for the FFU casing? A: We offer several material options including SUS304 stainless steel, SUS201, Coated Steel, and Galvanized Steel to suit different environmental requirements.

Q3: What filtration efficiency can these units achieve? A: Our FFUs are equipped with HEPA or ULPA filters, achieving efficiencies of 99.99% to 99.995% for particles as small as 0.3 microns (H13/H14 grades).

Q4: Is the air velocity adjustable? A: Yes, the units feature adjustable speeds, typically maintaining an average air velocity of 0.35m/s to 0.45m/s.

Q5: What is the noise level during operation? A: The units are designed for low-noise performance, generally operating between 49 and 63 dBA, depending on the model and settings.

Q6: Can these units be used in low-ceiling cleanrooms? A: Absolutely. With a profile thickness as low as 23cm, these units are specifically designed for environments with very low space above the false ceiling.
