Product Overview
The EFU (Equipment Fan Filter Unit) is an ultra-thin fan filter unit specifically engineered for clean air applications where installation space is severely restricted. With a compact profile ranging from 70mm to 190mm in height, it is designed to be embedded directly into production equipment tops or low-ceiling plenum spaces, delivering localized Class 100 (ISO 5) clean air precisely where it is needed most.
Key Applications
- Space-limited equipment: SMT mounters, lithography machines, wafer inspection tools, and other precision manufacturing equipment with extremely tight overhead clearance
- Low-ceiling retrofits: Aging factory buildings or cleanrooms with insufficient plenum height where standard FFU (280–320mm) cannot be installed
Core Advantages
- Ultra-slim footprint (70–190mm height) – enables installation in the most confined overhead spaces
- Targeted microenvironment control – creates a positive-pressure clean zone directly over the critical work area, isolating contamination at the source
- Low vibration design – minimizes interference with precision alignment processes (e.g., SMT placement, lithography)
- Flexible maintenance – supports top-access or bottom-access filter replacement to accommodate tight installation constraints
- Customizable sizes – dimensions tailored to match specific equipment footprints
