FFU Fan Filter Unit Generates Positive or Negative Pressure with Airfoil Turbo Fan Motor

An FFU (Fan Filter Unit) is a device commonly used in clean rooms and controlled environments to maintain air cleanliness and quality. It combines a fan with a high-efficiency particulate air (HEPA) or ultra-low penetration air (ULPA) filter.

Air Filtration: FFUs are equipped with HEPA or ULPA filters that capture airborne particles, including dust, pollen, mold spores, and bacteria. This helps maintain the cleanliness of the air in controlled environments.

Airflow Distribution: FFUs circulate filtered air throughout the clean room or controlled space, ensuring a consistent and uniform airflow. This is critical for minimizing dead spots and maintaining clean air across the area.

Positive or Negative Pressure Control: Depending on the application, FFUs can be used to create either positive or negative pressure environments, which is important for preventing contamination in sensitive areas.

Energy Efficiency: Many FFUs are designed to be energy-efficient, utilizing variable speed fans that can adjust airflow based on the specific requirements of the environment.

Applications:

• Clean Rooms: Widely used in pharmaceutical, biotechnology, semiconductor manufacturing, and research laboratories where air quality is critical.
• Biological Safety Cabinets: FFUs are often incorporated into these cabinets to provide a sterile working environment for handling hazardous biological materials.
• Operating Rooms: Used in medical facilities to maintain sterile conditions during surgeries.
