FFU (Fan Filter Unit)
High-Efficiency Fan Filter Unit for Cleanrooms
A Fan Filter Unit (FFU) is a self-contained ceiling-mounted air filtration device used in cleanrooms. It draws in ambient air through a HEPA or ULPA filter and delivers a uniform Laminar Flow of clean air into the controlled environment. VOV's innovative FFU is engineered for maximum energy efficiency, low noise levels, and easy maintenance. Ideally suited for the electronics, pharmaceutical, and food industries.

FAQ
What is the difference between AC (Standard) and EC (Advanced) motors in FFU units?
AC motors are cost-effective standard models with 3-speed adjustment, suitable for general cleanrooms. EC motors (Electronically Commutated) are an advanced technology, saving 30-50% more energy. They offer precise 0-100% speed control and support integration with central Control Systems. Ideal for long-term Smart Factory applications.
Which cleanroom classes require a Fan Filter Unit (FFU)?
FFUs can be used in all cleanroom levels from ISO Class 1 to ISO Class 8. The quantity and layout of FFUs increase with the stringency of the cleanroom class. For example, ISO Class 5 may require FFU coverage of over 60% of the ceiling to achieve perfect Laminar Flow.
