Cleanroom FFU Air Supply Outlets with Gel Seal HEPA Filter

 

1. Construction of FFU

An FFU is a self-contained, modular air purification device primarily consisting of the following components:

 

1.1. Housing

   Normally made of aluminum-zinc coated steel.

   Designed to be lightweight yet robust, with a slim profile for easy integration into cleanroom ceiling grids.

   The interior is often baffled to ensure uniform airflow distribution across the filter.

 

1.2. DC Fan System

   Utilizes one high-efficiency, low-noise DC motor.

   DC Motor offer superior energy efficiency, precise speed control, and long service life compared to traditional AC motor.

   The fan is designed for stable operation and provide a consistent pressure drop to overcome system resistance.

 

1.3. Filtration System

   Equipped with a primary pre-filter (typically G4 grade) to capture larger particles and extend the life of the main filter.

   The core component is a HEPA (High-Efficiency Particulate Air) filter or ULPA (Ultra-Low Penetration Air) filter.

   HEPA filter is certified to remove at least 99.95% of particles as small as 0.3 micrometers.

   The filter is securely sealed within the housing to prevent bypass leakage.

 

1.4. Control System

   Individual Unit Control: Each FFU can be equipped with a manual speed controller (potentiometer) or a more advanced digital controller with a display.

   Group Control System (Optional): Multiple FFUs can be networked and controlled centrally via a Building Management System (BMS) or a dedicated DDC (Direct Digital Control) system. This allows for monitoring and adjusting airflow, monitoring filter status, and managing alarms across the entire cleanroom.

 

2. Product Features

2.1. High Efficiency and Performance

   Provides unidirectional (laminar) vertical airflow to create and maintain ISO Class 1-5 cleanroom environments.

   Ensures a consistent and uniform air supply with low turbulence.

 

2.2. Energy Saving

   The use of DC motor technology significantly reduces energy consumption, often by more than 30% compared to AC motors.

   Speed can be precisely adjusted to match the actual cleanliness requirements, further optimizing energy use.

 

2.3. Easy Installation and Maintenance

   Modular and standardized design allows for quick plug-and-play installation into T-grid ceilings.

   Filters can be easily accessed and replaced from the cleanroom side without tools in many designs, minimizing downtime.

 

2.4. Low Noise and Vibration

   Advanced fan blade design and vibration-damping materials ensure quiet operation, typically below 58 dB(A), providing a comfortable working environment.

 

2.5. Flexibility and Scalability

   Ideal for retrofitting existing rooms or building new modular cleanrooms.

   The system can be easily expanded or reconfigured by adding or relocating FFUs.

 

2.6. Reliability and Durability

   Built with high-quality components for long-term, 24/7 reliable operation.

   Designed to meet stringent industry standards for cleanroom applications.
