FFU

The FFU (Fan Filter Unit) is a self-contained ceiling-mounted air purification module, specifically designed for both turbulent and laminar flow cleanrooms. It features a modular design for flexible installation and seamless connection. With a consistent outlet wind speed of 0.45m/s ±20%, it ensures stable and reliable air distribution, making it ideal for various high-cleanliness environments such as pharmaceuticals, electronics, and biotechnology.

Description

An FFU (Fan Filter Unit) is a critical terminal air supply device designed for cleanrooms and clean workshops. Combining a fan and a HEPA/ULPA filter in a single module, the FFU provides laminar airflow without the need for complex ductwork. Its flexible design allows for easy customization based on specific airflow and dimensional requirements, enabling rapid installation and layout adaptation.

Widely used across industries such as pharmaceuticals, electronics, food processing, and more, the FFU delivers efficient, reliable, and scalable filtration performance. Whether upgrading existing facilities or implementing new clean air zones, the FFU offers an energy-saving and cost-effective solution for maintaining high air purity standards.

Choose FFU systems for enhanced airflow control, reduced installation time, and consistent compliance with stringent cleanroom classifications.

Advantages of FFU (Fan Filter Unit)

1. Easy Replacement, Installation & Mobility:

FFUs are self-powered and modular, making them easy to relocate and maintain. Their accompanying filters can be replaced effortlessly, allowing flexible zoning control and on-demand adjustments in cleanrooms.

2. Negative Pressure Ventilation

This is a unique feature of FFUs. They generate static pressure, ensuring the cleanroom maintains positive pressure relative to the outside. This prevents external particles from leaking in, simplifying and enhancing sealing safety.

3. Shorter Construction Cycle

The use of FFUs eliminates the need for duct manufacturing and installation, significantly reducing construction time.

4. Reduced Operating Costs

Although the initial investment may be higher than ducted systems, FFUs offer notable long-term benefits in energy efficiency and minimal maintenance.

5. Space Efficiency

Compared to other systems, FFUs require less vertical space in supply air plenums and occupy almost no floor space within the cleanroom itself.

Frequently Asked Questions

1.What filters does an FFU (Fan Filter Unit) typically consist of?

An FFU is usually composed of HEPA filters, with an efficiency ranging from H11 to H14. The thickness of the filter is typically 70mm, and the common size is 1170*570*70mm. 870*870*70mm,570*570*70mm

2. How often should I replace the HEPA filter in an FFU?

A primary filter (nylon mesh filter) is used in front of the fan. This filter can be cleaned, effectively extending the service life of the high-efficiency filter. The replacement cycle of a HEPA filter is usually 3 to 6 months.

3. Can FFUs be used in modular cleanrooms?

Yes, FFUs are ideal for modular cleanrooms. Their compact and self-contained design allows for easy integration into grid-based ceiling systems. They provide efficient recirculated filtration and can be combined to create ISO 5 (Class 100) or higher cleanliness environments quickly and cost-effectively.

DTAF customers' evaluation of the FFU

The purification capacity (CADR) of this purifier is quite large, large enough to blow through the filter element, as large as a direct-blown fan.
