FFU and Terminal Air Purification Equipment
Floor-Standing Fan Filter Unit
A self-supporting filtered-air station that places an FFU at process height on a rigid floor frame for localized horizontal clean-air coverage.
- Self-Supporting Frame
- Process-Height Air Delivery
- Adjustable Levelling Feet
- Single or Twin FFU Layout
Product Introduction
The floor-standing fan filter unit mounts one or two standard filter modules in a reinforced steel frame rather than in a suspended ceiling. Its fixed-height legs carry the fan mass and align the discharge face with the work surface, while wide levelling pads compensate for uneven floors. Power and speed controls are routed along the rear uprights to keep the clean-air face clear. This arrangement establishes a local horizontal clean zone beside production machinery, transfer openings or benchtop operations without modifying the building ceiling system.
Key Features
The elevated module aligns filtered discharge with benches, conveyors and equipment access openings.
Rear cable routing keeps electrical leads away from the clean airflow and operator path.
Single- and twin-module frames permit the protected width to be matched to the process footprint.
Customer Product Concerns
A fixed clean-air source is often needed beside existing equipment where neither ceiling reconstruction nor constant relocation is desirable.
Retrofitting a ceiling grid for one local process causes disproportionate shutdown and construction work.The self-supporting floor frame adds filtered airflow without opening the overhead envelope.
A low temporary purifier directs clean air below the actual handling surface.The raised FFU face is positioned at the working elevation for useful horizontal coverage.
Uneven floors cause a tall clean-air wall to lean and misdirect the airflow plane.Four adjustable levelling feet establish a stable vertical frame and repeatable outlet alignment.
Power cables crossing the front of the unit obstruct cleaning and material movement.Rear uprights conceal protected cable routes and keep the discharge side uncluttered.
Typical Applications
Temporary clean production cellsEquipment loading interfacesBenchtop assembly protectionPackaging and inspection stationsCleanroom retrofit areas
