Components:
Enclosure: Commonly made of galvanized aluminum alloy coated steel plate, aluminum alloy, or stainless steel, used to support the fan, air guide ring, and air deflector.
Air Deflector: Built into the enclosure around the fan below, its function is to evenly distribute the airflow.
Fan: The core component of the FFU, available in single-phase AC, DC, and three-phase AC types, responsible for generating airflow and driving the air purification process.
Filters: Includes a pre-filter at the inlet and a high-efficiency/ultra-high-efficiency filter at the outlet, used to filter dust, bacteria, and other pollutants from the air.
Control Components: AC FFUs commonly use a five-speed controller or a stepless speed controller; the control chip for DC systems is embedded inside the motor, allowing for remote control via dedicated software.
Working principle:
The built-in fan generates airflow, which draws in indoor air through the air inlet. The air passes through a high-efficiency filter to remove dust, bacteria and other particulate matter. The filtered clean air is then uniformly delivered into the room at a wind speed of 0.45m/s±20% across the entire air outlet surface, completing the air purification process.
Features:
High Purity Level: Static purification level can reach 10 to 100.
Uniform Airflow: Uniform airflow velocity at the outlet surface, delivering air at a consistent speed of 0.3-0.5 m/s.
Low Noise: Noise level is typically ≤58dB.
High Filtration Efficiency: Employs a plate-less HEPA filter, achieving a filtration efficiency of up to 99.99%.
Low Energy Consumption: Utilizes a stepless speed control design, allowing for adjustable airflow to reduce operating costs.
Applications:
Widely used in cleanrooms, clean benches, clean production lines, modular cleanrooms, and localized Class 100 environments in industries such as semiconductors, electronics, flat panel displays, disk drives, optics, and biotechnology, as well as other locations with strict air pollution control requirements, such as laboratories, data centers, and hospital operating rooms.
