Core Value of FFU in HVAC Field
In the field of Heating, Ventilation and Air Conditioning (HVAC), fan filter unit with HEPA filter is a critical equipment for maintaining ultra-clean environments in specialized spaces. This integrated air purification system combines high-performance fans with HEPA filtration technology to provide precisely controlled laminar airflow, making it particularly suitable for applications in fan filter units clean rooms.
Excellent Operating Mechanism of FFU
Standard FFU equipment operates based on three core technical principles:
Air Intake: Built-in centrifugal fan draws ambient air from the top of the unit
High-Efficiency Filtration: HEPA multi-stage filtration system captures 0.3 micron particles with 99.999% efficiency
Uniform Air Supply: Processed clean air is evenly discharged at a speed of 0.45±0.09 m/s
