Product application
Compact multi-purpose clean unit functioning as an FFU (Fan Filter Unit). Suitable for a wide range of applications: plug in power and it supplies purified air. The housing is made of anti-static plastic to reduce dust adhesion. Lightweight, easy to install and maintain, with an aesthetic design.

What is an FFU?
An FFU (Fan Filter Unit) integrates a high-efficiency HEPA filter and a blower in a single clean air module. FFUs are used to ensure cleanliness in cleanrooms, clean booths and semiconductor manufacturing equipment. Installation methods include floor mounting, wall mounting and ceiling suspension depending on site conditions. Our compact lightweight FFU types (SS-MAC, EC-MAC, etc.) are widely used in modern cleanrooms.
