Cleanroom Fan Filter Units (FFU )

Filter Fan units offer a versatile and cost-effective method for eliminating particles from the recirculated air in both turbulent and unidirectional type cleanrooms.

Filter fan units are self-contained systems featuring an integrated HEPA filter, fan, and control mechanism. They deliver purified air to cleanrooms and laboratories in the life sciences, food and beverage, and microelectronics sectors by eliminating harmful airborne particles from recirculating air. Unlike pressurized cleanroom ceiling plenums, FFUs generate positive room pressure, thereby minimizing the risk of contamination from potential ceiling bypasses.

Standard:

FFUs are engineered to provide consistent airflow, meeting standards such as Federal Standard 209E

Features:

Integrated HEPA/ULPA Filters: FFUs are equipped with High-Efficiency Particulate Air (HEPA) or Ultra-Low Penetration Air (ULPA) filters. HEPA filters can remove 99.97% of particles as small as 0.3 microns, while ULPA filters are even more efficient, capturing 99.999% of particles as small as 0.12 microns.

Variable Speed Control: Many FFUs come with adjustable speed controls, allowing users to regulate the airflow to meet specific cleanroom requirements.

Low Noise Operation: FFUs are designed to operate quietly, which is crucial in environments where noise levels need to be minimized.

Energy Efficiency: Modern FFUs often feature energy-efficient motors, such as electronically commutated motors (ECMs), which reduce power consumption and operational costs.

Compact and Modular Design: FFUs are typically designed to be compact and modular, making them easy to install in various configurations, including ceiling grids and wall mounts.

Durable Housing: The housing of FFUs is usually made from robust materials like aluminum or steel, ensuring durability and longevity.

Advanced Monitoring Systems: Some FFUs are equipped with monitoring systems that provide real-time data on filter performance and alert users when filters need to be replaced.

Positive Pressure Maintenance: FFUs help maintain positive pressure in cleanrooms, reducing the risk of contamination from external sources.

Major Applications:

Filter fan units (FFUs) are self-contained systems that include a HEPA filter, fan, and control mechanism. They deliver clean air to environments such as cleanrooms and laboratories in the life sciences, food and beverage, and microelectronics sectors by eliminating harmful airborne particles from the air. Unlike pressurized cleanroom ceiling plenums, FFUs generate positive room pressure, which minimizes the risk of contamination from potential ceiling leaks.
