The LYC-A25 portable oil purifier is a compact, high-efficiency oil filtration system designed for on-site purification of hydraulic fluids, lubricating oils, and other industrial oils. With a rated flow of 25 L/min, this portable unit delivers reliable, cost-effective oil cleaning for a wide range of applications including new oil filtration, system oil addition, in-service oil purification, and hydraulic system bypass filtration.
Engineered with a motor-driven dedicated gear pump, the LYC-A25 features low noise operation, strong self-priming capability, and smooth, stable performance. The unit employs a dual-stage filtration system — a 100μm coarse inlet filter protects the pump and extends main filter life, while a precision filter (available in 3μm, 5μm, 10μm, 20μm, or 40μm) removes fine particulate contaminants to restore oil to cleanliness standards.

Xinxiang City Huahang Filter Co., Ltd. is an ISO 9001 certified professional manufacturer specializing in the design, production, and sale of hydraulic filter elements, replacement filters, and industrial filtration solutions. Established in 2003, the company operates from a modern manufacturing facility in Xinxiang City, Henan Province – one of China’s most established filtration industry clusters.
Our workshop is equipped with automated paper folding machines, end cap assembly lines, and testing equipment to ensure consistent quality across every batch. Most of our workers have many years of experience here, familiar with every stage of production. We believe that good products stem from a dedicated attitude and solid craftsmanship.
The LYC-A25 Portable Oil Purifier is widely used across multiple industries and applications:
New Oil Filtration: Filters new oil before it is added to systems, removing contaminants introduced during storage and transportation
System Oil Addition: Filters oil while adding to hydraulic or lubrication systems, ensuring only clean oil enters the equipment
In-Service Oil Purification: Cleans oil that is currently in use, removing accumulated contaminants and extending oil life
Hydraulic System Bypass Filtration: Operates as a parallel filtration loop independent of the main system, providing continuous oil cleaning
Pre-Commissioning System Flushing: Circulates and filters oil through new or repaired systems before startup to remove debris
Industrial Machinery: Hydraulic system maintenance for presses, CNC machines, gearboxes, and turbines
Power Generation: Transformer oil purification and turbine lubrication system conditioning
Mobile Equipment: Fluid servicing for marine, mining, and construction equipment hydraulic systems
Precision Manufacturing: Injection molding machine oil recycling and aerospace hydraulic fluid polishing
The LYC-A25 Portable Oil Purifier operates through a straightforward, effective two-stage filtration process:
Stage 1 – Coarse Filtration (100μm): Contaminated oil is drawn into the unit by the gear pump through an inlet strainer that captures large debris (≥100μm), protecting the pump and downstream components from damage.
Stage 2 – Precision Filtration (3–40μm): The oil then passes through the precision filter element, where graded-depth media removes fine particulate contaminants. The filtration accuracy can be selected based on application requirements — from 3μm for high-precision systems to 40μm for general industrial use.
Real-Time Monitoring: A pressure gauge on the panel continuously displays the system pressure. An increase in differential pressure indicates filter saturation — replace the element when ΔP reaches 0.2 MPa.
Clean Oil Return: Purified oil is returned to the reservoir or equipment through the outlet, ready for use.
Q1: What types of oil can the LYC-A25 filter?
A: The LYC-A25 is suitable for hydraulic oil, lubricating oil, transformer oil, gear oil, and other petroleum-based mineral oils. It can also handle fire-resistant fluids such as water-glycol (BH) and phosphate ester (V) with appropriate configurations.
Q: Can the LYC-A25 be used as a bypass filter?
A: Yes. The unit can be connected in parallel to an existing hydraulic or lubrication system as a bypass filtration loop, providing continuous oil cleaning without interrupting normal system operation.
Q: Is the LYC-A25 suitable for transformer oil?
A: Yes. The LYC-A25 can be used for transformer oil purification. For applications requiring degassing and dehydration, please consult us for specialized equipment.
