Product description

The MINI Small Fan Filter Unit (FFU) is a compact and highly efficient air filtration system designed to provide clean and controlled airflow in critical environments. It is a versatile and reliable solution for maintaining air quality and minimizing contamination in various applications.

Fan filter units consist of a backward incline fan motor assembly and high-efficiency HEPA/ULPA filter are combined in one unit. The fan filter units are designed to furnish Hepa filtered airflow over the cleanroom area. Our fan filter units (FFU) are used in all applications and classes of cleanroom environments, semiconductor medical manufacturing facilities, as well as pharmaceutical labs. Cleanseal fan filter units are designed for use in Class 10 through Class 100,000 cleanroom spaces.
