Fan/Filter Units (FFUs)


Filter Units provide the micro-filtered airstream that controls particulate contamination in a cleanroom or laminar flow clean bench. Terra's comprehensive line includes models based on High-Efficiency Particulate Air (HEPA) filters, rated 99.99% efficient @ 0.3 µm particles, and Ultra Low Penetration Air (ULPA) filters, rated 99.999% efficient @ 0.12 µm particles. Select the lights and other ceiling grid accessories to complete your system.
