The DSX Equipment Fan Filter Unit (EFU) EF-DE400H45x1 is an integrated industrial air purification terminal tailored for automated production machinery, precision processing stations and compact micro clean zones. As a professional Chinese EFU manufacturer, WUJIANG DESHENGXIN PURIFICATION EQUIPMENT CO., LTD independently develops and produces this standard square EFU with SPCC cold rolled steel housing. Equipped with our self-manufactured EC fan and control modules plus multi-grade high-efficiency filters, it generates steady laminar clean airflow to eliminate airborne particulate contamination inside production equipment.
Featuring a slim, space-saving structure for top-mounted installation, this industrial EFU is widely deployed in lithium battery production, semiconductor wafer processing, optical inspection, precision electronics assembly and lab precision instrument industries. It creates reliable localized ultra-clean environments to reduce dust-induced product defects.

All EC fan motors and matching drive control boards are fully self-developed and manufactured in our own workshop, no outsourced core components.
Independent R&D motor structure delivers higher energy efficiency, lower noise and longer continuous service life;
Customizable control logic including stepless speed regulation, constant wind speed mode, linkage signal communication and alarm feedback;
Stable compatibility with long-term 24/7 factory operation, short lead time for customized control functions, reliable after-sales component replacement without third-party supply restrictions.

Multiple Filter Grade Options for Diverse Cleanliness Requirements
Flexible filter grade selection to match different clean class demands: H13, H14, U15, U16, U17 available.
All filters adopt micro glass fiber media with integrated sealing strips for full airtightness and zero leakage:
H13 / H14: 99.99% filtration efficiency for 0.3μm particles, widely used for Class 100 clean workshops;
U15 / U16 / U17: Ultra-high efficiency ultra-pure filters, applied for high-end semiconductor, medical and ultra-micro precision manufacturing scenarios.

We offer full personalized customization to meet unique production demands:
Custom overall external dimensions to fit special equipment installation spaces;
Adjustable airflow range, matched with self-produced EC motors to achieve target air volume;
Optimize internal air duct structure to upgrade outlet wind speed uniformity, eliminate turbulence and uneven airflow;
Custom control modes, filter grades, sealing structures and surface treatments as requested.
The unit housing is manufactured with high-strength structural materials featuring excellent anti-deformation performance. The standard configuration adopts SPCC cold-rolled steel with integrated forming process, ensuring superior structural strength and rigidity for long-term industrial operation. Pre-reserved mounting holes support quick installation and firm locking, perfectly fitting standard equipment frames for easy assembly.
For applications with special environmental requirements, we offer flexible material upgrade options including:
SUS304 / SUS316 Stainless Steel – for corrosive environments, chemical exposure, or high-humidity conditions
Aluminum Alloy / Aluzinc Steel – for lightweight and anti-static applications
Special Surface Treatments – anti-static coating, anti-corrosion coating, or other functional finishes as requested
All housing options can be customized in dimensions, thickness, and structural configurations to meet specific equipment integration needs, with the same reliable quality assured by our full in-house manufacturing chain.
The DSX EFU features an ultra-thin body design engineered to minimize the footprint inside production equipment, leaving ample room for core functional modules and enabling a streamlined machine layout. For applications with extreme space constraints, we offer a dedicated ultra-slim version with a housing height as low as 70 mm – a dimension that redefines industry standards for compact clean air solutions.
The internal air duct is precisely optimized through advanced computational fluid dynamics (CFD) to reduce airflow resistance while delivering uniformly distributed vertical laminar airflow – completely free from turbulence or vortex – ensuring a stable and consistent local clean zone for sensitive processes.
The efficiency gains are twofold: lower pressure drop reduces energy consumption, while uniform airflow extends HEPA/ULPA filter service life by preventing uneven loading and localized premature clogging, minimizing filter replacement frequency and maintenance downtime.
Whether you need standard thickness or our special 70 mm compact version, the DSX EFU delivers proven reliability, filtration performance and intelligent control – now in a form factor that saves space, cuts energy use, and enhances equipment longevity.
Modular Design for Cost-Effective Maintenance
The DSX EFU adopts a fully modular architecture with independent, replaceable functional modules – including the EC fan motor, HEPA/ULPA filter, and control board. Each module can be replaced individually when needed, eliminating the need for complete unit replacement and significantly reducing long-term maintenance costs.
The filter replacement is performed via side-access design using standard tools – simply remove the housing screws, slide out the spent filter, and insert a new one. The screw-lock sealing design ensures uniform compression force around the filter frame, delivering superior airtightness and eliminating bypass leakage.
This modular approach minimizes downtime, simplifies spare parts inventory, and extends overall equipment service life. Combined with unified specifications across the EFU series, it delivers the lowest total cost of ownership for your production lines.

The self-produced built-in EC fan draws surrounding air into the EFU unit, forcing all air to pass through the selected H13/H14/U15/U16/U17 high-efficiency filter. Micro dust particles are fully trapped by glass fiber filter media. Purified clean air flows vertically downward at stable customized velocity, forming an independent unidirectional clean microenvironment inside equipment. It isolates external dust pollution, lowers product reject rates and stabilizes processing quality.
