FFU: A core purification tool for creating clean environments across multiple industries
High-efficiency purification, precise dust control
The FFU (Fan Filter Unit) comes with a built-in fan and high-efficiency filter. During operation, the fan draws in air from the top, first filtering large dust particles through a pre-filter, and then further filtering by a high-efficiency filter (such as HEPA/ULPA). For particles ≥0.3μm, the filtration efficiency can reach over 99.99%, with some ultra-high-efficiency models even reaching 99.9995%. It can quickly purify local spaces to Class 100 to Class 100,000 cleanliness, meeting the stringent requirements of various scenarios.
Technological highlights, energy saving and flexibility
The FFU adopts a modular design, with standard dimensions for easy and quick installation. Multiple units can be flexibly connected in series or parallel, easily adapting to both new cleanrooms and renovation projects. Its energy-saving advantages are significant; the use of DC brushless motors (EC motors) or energy-saving AC motors reduces power consumption by 30%-50% compared to traditional systems. It also supports three-speed adjustment or stepless speed regulation, and multiple devices can be centrally controlled via computer, enabling remote monitoring and fault diagnosis. Operating noise as low as ≤54dB(A) and vibration velocity <1.0mm/s, creating a comfortable environment for cleanrooms.
Widely applicable and adaptable to various situations, FFUs have a wide range of applications. In the semiconductor and electronics manufacturing industry, they provide high-cleanliness air for cleanrooms and around lithography machines, preventing micro-dust contamination of products; in the biopharmaceutical industry, clean benches, biosafety cabinets, and animal laboratories use FFUs to create sterile operating spaces, ensuring experimental and production safety; in food and cosmetics production, FFUs are used in packaging workshops and filling lines to extend product shelf life and improve quality; in precision manufacturing and optics, processes such as lens assembly and LCD panel production rely on FFUs to ensure high-precision processing is not affected by particulate matter.
Key to Selection: Matching to Needs
When selecting a filter, choose the type based on cleanliness requirements. Ultra-high efficiency (ULPA) filters are used for Class 100 environments, while high-efficiency particulate air (HEPA) filters are chosen for Class 100,000 environments. Select standardized or customized sizes based on space dimensions to ensure compatibility with the ceiling joists. For small-scale scenarios, single-unit manual control is sufficient; for large-scale projects, computer cluster control is recommended for efficient management.
With its high purification efficiency, energy-saving flexibility, and wide application, the FFU (Fan Filter Unit) has become the preferred equipment for creating clean environments in many industries, continuously safeguarding precision production and scientific research experiments.
