Main Specification for FFU

Features at a Glance

• Core Purification Function

  • Particle Filtration: The integrated HEPA or ULPA filter efficiently removes airborne particulate contaminants (such as dust, microbes, and aerosols) from the airflow. This is critical for achieving the required cleanliness class in ISO Class 5 (Class 100) and higher cleanrooms.

  • Delivery of Clean Air: It draws in "dirtier" air (from the turbid room interior or return air) and supplies filtered "clean air" continuously, providing a consistent stream of air that meets the specified cleanliness standards.

• Airflow Organization & Recirculation Function

  • Creation of Unidirectional (Laminar) Flow: When multiple FFUs are installed across the cleanroom ceiling in a densely packed array, they generate a uniform, vertical downward unidirectional airflow. This acts like an "air piston," swiftly pushing contaminants toward the return air vents.

  • Primary Air Recirculation Driver: The built-in fan provides the motive force for air movement. It forms an independent, modular recirculation system that can work in conjunction with the Make-Up Air Unit (MAU) or, in some designs, operate independently, offering high flexibility.

• Environmental Control & Maintenance Function

  • Positive Pressure Maintenance: By continuously supplying air into the room, FFUs help maintain positive pressure relative to external areas or adjacent lower-classification zones, preventing the infiltration of unfiltered air.

  • Air Velocity & Uniformity Control: Most FFUs feature variable speed control (via AC, DC/EC motors or frequency conversion), allowing precise adjustment of supply air velocity and volume. This ensures stable and uniform airflow in the working zone, meeting cleanliness requirements while optimizing energy efficiency.

  • Auxiliary Temperature & Humidity Control: While FFUs do not condition air themselves, the stable, large-volume airflow they create facilitates the rapid and even distribution of temperature- and humidity-controlled air supplied by the HVAC system throughout the workspace, preventing local hot spots or dead zones.

• System & Operational Advantages

  • Modularity & Flexibility: Each FFU is an independent unit, making installation, replacement, and maintenance straightforward. The layout can be easily reconfigured by adding, removing, or relocating units.

  • Space Saving: Integrating the fan and filter within the ceiling plenum eliminates the need for large centralized ductwork and air handling units, reducing the required floor-to-floor height.

  • Energy Efficiency Potential: FFUs equipped with high-efficiency Electronically Commutated (EC) motors often operate more efficiently at partial loads compared to traditional large fan systems. When integrated with intelligent control systems, they can enable zoning and demand-based operation of FFU clusters, leading to significant energy savings.

  • Ease of Maintenance & Monitoring: Filter replacement can be performed online for individual units without system shutdown. Modern FFUs can be equipped with monitoring modules to provide real-time feedback on operational status (air velocity, filter differential pressure, alarms, etc.) to a central control system.

Products Description

• HEPA filter: HEPA filters represent the ideal synergy between high-efficiency filtration and forced-air conveyance.
• Handles: handles formalize enhanced safety, operational convenience, and procedural reliability during both installation and maintenance operations.
• Safety net: This shift from reactive risk response to proactive risk management in cleanroom control drastically cuts the likelihood of batch loss, recalls, or downtime caused by environmental deviations, delivering critical stability and reliability for high-value production.
• Adjustable knob: This fine‑tuning capability empowers engineers and operations staff with enhanced flexibility, enabling a more precise, economical response to complex, dynamic real‑world requirements—thereby ensuring optimal and robust cleanroom performance.
