Product Introduction
The LUCA multi-stage portable fine oil purifier trolley is a patented mobile oil filtration device, specially developed for scenarios requiring superior oil cleanliness. It integrates four progressive filtration stages, and the built-in hydraulic filter forms a complete graded filtration pipeline. With ergonomic push handle, heavy-duty casters and compact base frame, the trolley can be flexibly moved between hydraulic stations, machine tools and construction machinery. It supports AC220V single-phase and AC380V three-phase power supply options, and the final fine filtration precision can be selected from 3μm,5μm,10μm,20μm,30μm to satisfy diverse precision requirements of servo systems and precision hydraulic equipment.
Working Principle
Contaminated oil is sucked into the system by the transfer pump. It passes sequentially through four filter stages for step-by-step purification. The first-stage 100μm coarse filter captures large debris to protect the pump; the second 80μm and third 50μm filters intercept medium-sized particles progressively; the fourth fine filter removes tiny sludge and metal powder. The pressure gauge on the filter tank monitors internal pressure loss in real time. When the pressure rises to the set threshold, it indicates that the filter elements are clogged and need to be replaced. After layered filtration, clean oil flows out through the outlet hose and returns to the oil tank.

Core Advantages
1. Four-stage progressive graded filtration
Compared with conventional two-stage filter carts, the 100μm→80μm→50μm→fine filter layered structure reduces the burden on the final fine filter element, extends element service life and achieves higher oil cleanliness steadily.
2. Patented structural design
This LUCA series owns independent patent, optimized internal flow channel to keep low initial pressure loss, stable flow rate and low energy consumption during continuous filtration.
3. Flexible mobile trolley structure
Equipped with push handle and wear-resistant rolling casters, it is easy to push and steer in narrow workshop spaces for offline oil purification and new oil filling filtration.
4. Wide oil adaptability
Suitable for oil viscosity range from 10 cSt to 160 cSt, applicable temperature 5~80℃, compatible with hydraulic oil, gear oil and various industrial lubricants.
5. Dual power options
Supports 220V single phase and 380V three phase, adapts to different power supply environments of maintenance workshops and field service sites.
Application Scenarios

Precision servo hydraulic system oil purification
Machine tool, injection molding machine and metallurgical hydraulic station maintenance
Construction machinery and mining equipment lubricating oil filtration
Pre-filtration of new oil before injecting into equipment oil tank
Workshop routine oil cleanliness management and offline oil treatment
FAQ
Q1: What is the difference between LUCA and LUC filter trolley?
A1: LUC is two-stage filtration, while LUCA adopts four-stage progressive filtration. LUCA can reach higher cleanliness and has longer filter service life for high-precision hydraulic systems.
Q2: Can this LUCA filter cart remove water in oil?
A2: It is designed for solid particle filtration only. It cannot remove free water or dissolved water. If oil dehydration is required, please select our vacuum oil purifier series.
Q3: How to judge the replacement time of filter elements?
A3: Check the pressure gauge mounted on the filter tank. Once the differential pressure rises significantly, the filter cartridges are blocked and need replacement.
Q4: Can I customize the filtration precision?
A4: Yes, the final fine filter can be selected from 3μm,5μm,10μm,20μm and 30μm according to your system cleanliness requirement.
Q5: Are matching spare hydraulic filter cartridges available?
A5: Yes, we supply full set replacement filter elements for all LUCA models.
