HEPA Fan Filter Units (FFUs) are important components installed in ceiling areas of cleanrooms and other controlled environments. They are designed to remove particles and contaminants from the air, ensuring air quality meets stringent clean air standards. FFUs play a key role in HVAC systems in facilities where air purity is critical.
