The Deshengxin (DSX) Customizable EFU (Equipment Fan Filter Unit) is a high-efficiency clean air solution designed specifically for precision purification at the equipment level. Unlike conventional FFUs (Fan Filter Units) installed on cleanroom ceilings, the EFU is engineered for direct integration into production equipment, laboratory instruments, or automated assembly lines. Employing advanced filtration technology, it effectively removes airborne contaminants such as dust, particles, and pollutants, providing a clean and stable localized microenvironment for equipment. This significantly enhances equipment performance and operational reliability while reducing long-term maintenance costs.
With over two decades of experience in clean air equipment manufacturing and a unique full-industry-chain capability, Deshengxin produces all core components – motors, filters, and control systems – in‑house. This vertical integration ensures "core components self-manufactured, full process controlled," delivering a level of deep customization far beyond industry standards.
Full Industry Chain Manufacturing – Quality and Delivery Guaranteed
Deshengxin manufactures all critical components – EC motors, filters, and control systems – within its 30,000 m² facility. This vertical integration eliminates performance gaps and compatibility risks commonly found in assembled units, while ensuring that flexible customization does not compromise delivery lead times.
High-Efficiency Filtration for Precise Protection
The EFU can be equipped with HEPA (H13/H14) or ULPA (U15/U16/U17) grade filters, achieving up to 99.99% filtration efficiency for 0.3 μm particles. Filtration grades can be flexibly selected according to different cleanliness requirements, meeting needs ranging from Class 100 cleanrooms to ultra-clean environments in high-end semiconductor manufacturing.
Robust Construction for Harsh Conditions
The housing is integrally formed from SPCC cold-rolled steel, offering high structural strength and excellent deformation resistance. Alternatively, SUS304/SUS316 stainless steel or aluminum alloy can be selected to withstand exposure to process vapors or aggressive cleaning agents.
Intelligent Control for Precision and Reliability
An embedded intelligent control system supports multiple control logics such as stepless speed regulation and constant air velocity mode. Standard communication protocols (RS485, Modbus) enable direct integration with equipment PLCs. A built-in pressure gauge monitors filter condition in real time, and an automatic shut-off feature protects against abnormal pressure or temperature.
Low Noise, High Uniformity, Superior Performance
Proprietary motor technology and optimized fan and diffuser designs achieve extremely low noise levels. The plenum and diffuser system is optimized via CFD (Computational Fluid Dynamics) to ensure outlet air velocity uniformity better than ±15%.
Easy Maintenance, Time and Cost Savings
Standardized components and quick‑release structures allow filter replacement without special tools. The user-friendly interface and intuitive design significantly reduce routine maintenance time and operating costs.
