Portable Diesel Filtration: JY-DS219 Specifications & Benefits

Modular Ultra Fine Filter System Solutions

JY-DS219 Portable Polymer Membrane Fuel Purification Unit

The JY-DS219 is a portable polymer membrane fuel purification system designed specifically for high-precision requirements and compact spaces. This system is widely recognized in the fields of fuel quality inspection vehicles, mobile laboratories, and precision power assurance as a core piece of equipment for achieving “polishing”-grade fuel cleanliness. Its applications include deep purification of aviation jet fuel, pre-treatment for precision testing benches, and on-site sample fuel circulation purification.

The JY-DS219 is an ideal solution for problems such as damage to precision analytical instruments or failure of fuel injection systems caused by trace moisture, gum, and ultrafine particles in the fuel. It effectively achieves two-phase oil-water interface separation, physically intercepts micron-level impurities, and prevents secondary contamination from filter media shedding.

The core of the system utilizes Jingyuan® Polymer Asymmetric Microporous Membrane, achieving a near-absolute retention precision in the 2-15 μm range. Within a footprint of approximately 0.3 square meters, it integrates a pumping and dual-stage filtration system with a rated flow rate of 20-40 L/min.

The JY-DS219 provides measurable benefits to customers: significantly extending the service life of expensive detection instrument sensors (such as particle counters), ensuring finished oil meets extremely high ISO cleanliness standards prior to testing, and substantially enhancing field operation flexibility through its portable design.

The system offers excellent spatial adaptability, with external dimensions of approximately 670×450×465 mm, allowing for seamless integration into standard vehicle cabinets. Furthermore, the high-molecular polymer material possesses excellent chemical compatibility, supporting light diesel, aviation jet fuel, and various petroleum-based liquids.

JY-DS219 Key Advantages

The JY-DS219 offers significant advantages to customers, including deep dehydration via interface separation, extremely high performance density, full protection for precision instruments, and a stringent anti-static safety design.

1. Cross-Dimensional Interface Separation and Deep Dehydration Technology

Unlike traditional filter paper, which can only perform physical interception, the JY-DS219 utilizes the interface tension regulation characteristic of polymer membranes. Due to the extremely low surface tension of the membrane surface, it forces the coalescence and removal of water by leveraging the polarity difference between the oil and water phases. This mechanism effectively resolves oil turbidity and emulsification issues, reducing moisture content to extremely low levels and ensuring the fuel achieves analytical-grade transparency.

2. Performance Density Optimized for Mobile Operation Conditions

Within a confined space of just 0.3 square meters, the JY-DS219 achieves complete integration of “pump, pre-filter, and fine-filter.” Specifically tailored for the needs of mobile inspection vehicles, the equipment is not only compact but also utilizes a membrane material with excellent anti-fouling performance and a high cleaning recovery rate. This means that during field operations, customers do not need to frequently replace consumables, greatly reducing logistical support complexity.

3. Laboratory-Grade Precision Instrument “Firewall”

In fuel analysis tasks, the JY-DS219 is often deployed as the front-end protective layer for precision Particle Counters. By performing a pre-treatment “polishing” of the fuel entering the testing bench, it intercepts gum and hard particles that could damage precision sensors. This pre-treatment not only improves the accuracy of testing data but also provides long-term safety redundancy for expensive laboratory equipment.

4. Multi-Fuel Compatibility and System Safety Assurance

The equipment is widely applicable to light diesel, aviation jet fuel, and petroleum-based lubricating oils, capable of meeting the complex, multi-tasking demands of inspection vehicles. To address the propensity of low-conductivity fuels like aviation jet fuel to generate static electricity, the system strictly adheres to equipotential bonding and grounding standards during vehicle integration, effectively preventing risks caused by charge accumulation and ensuring high safety under any operating environment.

The JY-DS219 adopts asymmetric microporous membrane technology to provide a compact, high-precision, and high-reliability fuel purification solution, which helps to enhance fuel analysis accuracy and protect high-value testing assets.
