Fan filter units come with various technical features and specifications that make them suitable for different applications. The airflow rate of an FFU ranges from 200 to 2000 cubic feet per minute (CFM), depending on the size of the unit. The sound level of an FFU is typically less than 50 decibels, making it suitable for quiet environments such as hospitals and research labs. The energy consumption of an FFU is low, with some units consuming as little as 50 watts.

The filter efficiency of an FFU is also an essential specification. HEPA filters can remove 99.97% of particles as small as 0.3 microns, while ULPA filters can remove particles as small as 0.12 microns with 99.999% efficiency. The filter capacity of an FFU determines how often the filter needs to be replaced. It is essential to select an FFU with a filter capacity appropriate for the application.

The advantages of using an FFU are many. It provides clean and particle-free air in a controlled environment, improves the air quality, reduces the risk of contamination, and increases the efficiency of other air filtration systems in the building. It is also easy to install and maintain and comes with a long service life.
