Addressing the Industry "Space Crunch": Maximizing Space for Advanced Tools
In advanced semiconductor manufacturing (such as lithography, etching, and thin-film deposition) and advanced packaging, process equipment is becoming increasingly complex with highly dense internal components. Traditional standard FFUs (typically 250mm-350mm thick overall) are simply too bulky to fit into the narrow gaps within these tools. This forces equipment engineers into a dilemma: either increase the overall footprint of the tool or compromise on the internal laminar flow purification.
The Deshengxin Ultra-Thin EFU / FFU breaks this physical limit. With an overall operational thickness of only ~100mm, it can seamlessly slide like a "drawer" into the internal cavities, ceilings, or side walls of high-precision mini-environments, establishing a flawless unidirectional laminar flow barrier and drastically improving tool integration capabilities.
The Source Factory Advantage: How We Achieve the 70mm Breakthrough
Many brands cannot achieve such extreme thinness because they rely on assembling off-the-shelf standard parts. Deshengxin, as a true full-supply-chain source purification factory, re-engineers from the ground up:
70mm Custom Brushless Micro-Fan Housing: We do not use standard parts; instead, we independently developed an EC brushless micro-fan matched specifically for ultra-thin structures. Even within the extremely flat 70mm housing, it delivers powerful static pressure and highly stable airflow.
High Dust-Capacity Mini-Pleat Filters: The self-manufactured premium shallow-pleat HEPA/ULPA filter module perfectly mates with the 70mm housing. This ensures incredibly low resistance and filtration efficiency up to 99.9995% (@0.12μm) while keeping the total operational thickness to a strict ~100mm limit.
Core Product Features
Ultra-Compact Industry Benchmark: A 70mm fan housing and ~100mm total unit thickness free up valuable space inside the equipment, significantly reducing integration difficulty.
Uncompromised Aerodynamic Performance: Despite the ultra-thin size, the custom motor guarantees powerful and perfectly stable airflow, eliminating turbulent dead zones within the micro-environment.
Low Vibration & Low Noise: Utilizing aerospace-grade dynamic balance calibration and anti-vibration design, it perfectly suits semiconductor wafer handling processes that are hypersensitive to micro-vibrations.
Smart EC Group Control: Equipped with highly energy-efficient EC fans supporting the RS485 Modbus protocol, enabling stepless speed regulation, precise monitoring, and IoT integration for tens of thousands of EFUs.
Premium & Durable Materials: Available in corrosion-resistant SUS304/SUS316 stainless steel, lightweight aluminum alloy, or cost-effective powder-coated steel housings, with optional anti-static coatings for harsh wet or chemical environments.

Technical Q&A: In-Depth Look at the Ultra-Thin EFU/FFU
Q1: What exactly does "70mm" refer to? Is that the total operational thickness of the EFU/FFU?
A (Deshengxin Expert Response):
The "70mm" specifically refers to the extreme thickness of our custom-engineered ultra-thin EC brushless fan housing. When perfectly integrated with our high-capacity mini-pleat HEPA/ULPA filter, the total operational thickness of the entire EFU/FFU unit is approximately 100mm. Even at ~100mm total thickness, this remains an industry-leading benchmark, allowing the unit to slide effortlessly like a drawer into the tightest confines of semiconductor process equipment.
Q2: Does compressing the EFU/FFU to such extreme thinness compromise airflow or static pressure?
A (Deshengxin Expert Response):
Not at all. Many standard FFUs lose pressure when miniaturized because they rely on assembling off-the-shelf components. Because Deshengxin is a true full-supply-chain source factory, we custom-developed a specialized ultra-thin EC brushless micro-motor and optimized the internal aerodynamic fluid design specifically for this 70mm housing. This ensures that our EFU/FFU delivers powerful static pressure and highly stable airflow without any performance trade-offs in highly restricted spaces.
Q3: Are the vibration and noise levels suitable for highly precision semiconductor equipment?
A (Deshengxin Expert Response):
Absolutely. It is engineered exactly for vibration-sensitive, cutting-edge processes. We understand that advanced semiconductor wafer handling and lithography tools have zero tolerance for micro-vibrations. Our ultra-thin EFU/FFU utilizes aerospace-grade dynamic balance calibration and advanced anti-vibration structural designs, resulting in ultra-low vibration and exceptionally quiet operation that meets stringent high-end semiconductor requirements.
Q4: Can the dimensions, interfaces, and housing materials of the EFU/FFU be customized to fit our specific process tools?
A (Deshengxin Expert Response):
Yes, we offer comprehensive customization. Regarding materials, we provide premium options including corrosion-resistant SUS304/SUS316 stainless steel, lightweight aluminum alloy, and highly cost-effective powder-coated steel. Furthermore, as a direct manufacturer, we provide 1:1 OEM/ODM deep customization. We can tailor the exact length, width, air outlet shape, and special wiring interfaces precisely to your CAD drawings to ensure seamless integration.
Q5: How difficult is it to perform maintenance or replace the HEPA filter in such a highly compact space later on?
A (Deshengxin Expert Response):
We engineered this EFU/FFU with long-term maintenance in mind. The filter module and the fan housing feature a high-precision mating structure. When the HEPA filter needs replacement, maintenance engineers do not need to dismantle your large process tool. The filter can be quickly and efficiently swapped out directly from a designated access side, sliding out like a drawer, which significantly minimizes equipment downtime.
Q6: Do these ultra-thin EFU/FFU units support large-scale intelligent group control for massive semiconductor fabs?
A (Deshengxin Expert Response):
Fully supported. Deshengxin's EFU/FFU units are equipped with high-efficiency, smart EC brushless motors as a standard feature, fully supporting industrial communication protocols such as RS485 Modbus. This enables seamless integration into your facility's IoT or Facility Management Control System (FMCS). You can achieve stepless speed regulation, precise status monitoring, and fault alerts for tens of thousands of EFU/FFUs simultaneously.
