The AstroFan CleanZone DFU unit is designed to meet the growing demand for ready-to-use, quick supply, self-contained clean zones in many industry segments. The CleanZone DFU unit is a cost-effective answer to the need for local laminar down flow units, in order to meet strict cleanroom requirements.


Anodized aluminium extrusion cleanroom profiles form the base frame that holds the AstroFan FFU filter. Three sides of the base frame are fitted with fixed acrylic shields, while the entrance zone is provided with PVC stripe curtains. The AstroFan FFU provides nearly particle-free air into the CleanZone unit, creating a laminar down flow cleanroom environment. The air then leaves the Clean-Zone unit underneath the shields/curtain and recirculates into the surrounding environment. 

The standard execution of this unit includes acrylic shields and PVC stripe curtains as an enclosure. The AstroFan FFU unit is equipped with a single phase, 230 V 50 Hz drive motor, complete with either a 5-step or a stepless controller. A class H14 HEPA filter provides the required cleanliness for ISO.EN 14644-1 class 5 operation. Internal lighting is furbished as a 36 W fluorescent light.
