FFU (Fan Filter Units) that require precise cleanliness of environmental air (as per ISO 14644 standard flow environments) also need to operate in a laminar air flow in these situations. Mikropor produces Fan Filter Units with two stage filtration. Fan Filter Units (FFU) are based on a push and pull working principle, with environmental air drawn through a G4 class coarse filter to capture relatively large particles.

Thanks to Mikropor’s highly e¤cient HEPA class filters on the second stage, outlet air on the production lines will have the highest level of air purity. Mikropor produces standard or custom sized Fan Filter Units, designed and manufactured to meet the cleanroom application requirements.
