Ultra-Thin EFU (Equipment Fan Filter Unit) – Low-Profile Clean Air Solution for Space-Constrained Production Equipment & Low-Ceiling Cleanrooms
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

General-Purpose FFU (Fan Filter Unit) – Class 100 Local Cleanroom Air Purification for Semiconductor, Biotech & Optoelectronics
FFU Application Scenarios & Core Advantages
The core value of FFU (Fan Filter Unit) lies in providing stable, reliable local or overall clean air environments for spaces with stringent cleanliness requirements. Its primary applications include:
Large-Scale Industrial Cleanrooms: Widely used in electronics, semiconductors, flat-panel displays, optoelectronics, and new energy battery manufacturing, meeting cleanliness requirements of ISO Class 6 (FS209E Class 1000) and above.
Production Lines & Localized Purification: Can be used individually or in series to form continuous Class 100 (ISO Class 5) clean assembly lines, providing localized purification for critical processes such as precision component assembly and inspection.
Modular Clean Equipment: Serves as the core purification unit in constructing small-scale clean devices, including clean benches, clean booths, and clean transfer cabinets.
Key Advantages:
High flexibility and reusability, enabling zoned control and adaptable layout
Negative pressure design in the plenum relative to the cleanroom prevents unfiltered air leakage, enhancing safety
Shortens construction timelines, saves space, and reduces long-term operating costs.
Custom dimensions are available upon request. Standard cabinet sizes include 575×575×280 mm, 1175×575×320 mm, and 1175×1175×320 mm.

++DC FFU Fan Filter Unit for Clean Room
A Fan Filter Unit (FFU) is a self-contained air filtration system that is commonly used in cleanroom environments to remove contaminants from the air. It typically consists of a fan, a filter, and a motorized impeller that draws in air and passes it through the filter to remove particles. FFUs are commonly used to create positive air pressure in cleanrooms, and are also used in other applications that require clean air, such as in healthcare facilities and laboratories.
