1. Product Overview

The LYC High-Precision Oil Purifier is a mobile integrated oil purification equipment specially designed for various hydraulic 

systems. Engineered to address the critical need for maintaining hydraulic oil cleanliness, this purifier adopts a graded

 filtration structure that quickly removes solid particles, metal wear debris, and dust contaminants from hydraulic

 oil—effectively improving oil cleanliness and extending the service life of hydraulic components.

Key features of the LYC series include:

· Versatile application: Suitable for new oil filling, on-site bypass filtration, and used oil regeneration

· Compact and movable design: Ideal for daily maintenance in industrial workshops, construction sites, and power plants

· Easy operation: User-friendly controls requiring minimal training

· Cost-effective: Reduces oil replacement frequency and lowers overall maintenance costs

2. Product Performance

2.1 Hydraulic Oil Optimization

The LYC purifier is specifically optimized for hydraulic oil working conditions, adapting to conventional hydraulic oil

 viscosity ranges without damaging original oil additives. The filtration process is purely physical—no chemical reactions 

occur—ensuring that the oil's anti-wear, anti-oxidation, and anti-foam properties remain intact.

2.2 Graded High-Precision Filtration

Adopting a graded high-precision filtration structure, the LYC series effectively intercepts fine solid contaminants down to 

the micron level. This multi-stage approach:

· Captures particles of varying sizes in different filtration layers

· Extends filter element service life by distributing contaminant load

· Stably controls oil pollution level to meet NAS or ISO cleanliness standards

· Protects hydraulic precision components (pumps, valves, actuators) from abrasive wear

2.3 Compact & Mobile Design

Equipped with universal moving casters and a compact structure, the LYC purifier is:

· Easy for one-person handling and positioning

· Flexible for on-site oil filtering and replacement across multiple equipment locations

· Space-saving for workshops with limited floor area

2.4 Safe & Reliable Operation

The purifier features built-in overload and overflow dual safety protection, ensuring:

· Stable operation even under fluctuating inlet conditions

· Low noise output, suitable for noise-sensitive environments

· Support for long-time continuous working without performance degradation

7. Maintenance Guidelines

1. Differential Pressure Monitoring – Check the differential pressure indicator regularly. Replace filter elements when 

the indicator signals clogging (typically 2–3× initial clean pressure drop).

2. Element Replacement – Replace all filter elements in the graded filtration train simultaneously. Use only recommended 

replacement elements to maintain performance.

3. Frame Cleaning – Wipe the frame and control panel with a clean, dry cloth. Avoid water ingress into electrical components.

4. Caster Inspection – Check casters for smooth movement. Clean any debris wrapped around wheel axles.

5. Hose Inspection – Inspect inlet/outlet hoses for cracks, abrasion, or leakage. Replace if damaged.

6. Periodic Oil Sampling – Periodically test outlet oil cleanliness to verify filtration performance and determine optimal

 element replacement intervals.

8. FAQ (Frequently Asked Questions)

Q1: What types of hydraulic oil can the LYC purifier handle?

A: The LYC series is designed for conventional hydraulic oils (ISO VG 32, 46, 68, etc.). It is also suitable for lubricating oils

with similar viscosity grades. For synthetic or fire-resistant fluids, please consult our technical team for compatibility 

verification.

Q2: What is the filtration precision of the LYC oil purifier?

A: The LYC series adopts graded filtration. The final stage can achieve precision down to 3–5μm (absolute), effectively 

controlling oil cleanliness to NAS 1638 Class 6–8 depending on inlet condition and model selection.

Q3: Can the LYC purifier remove water from hydraulic oil?

A: The standard LYC configuration focuses on solid particle removal. For water removal (free and emulsified water), 

we offer optional dehydration filter elements or recommend our LYC-J series coalescing dehydration units.

Q4: Is the purifier suitable for continuous 24-hour operation?

A: Yes. The LYC purifier is designed for long-time continuous operation with built-in overload and overflow dual safety 

protection. Regular maintenance checks are recommended during extended operation.

Q5: How do I know when to replace the filter elements?

A: Monitor the differential pressure indicator on the control panel. When the needle reaches the red zone (typically 0.15–0.2 

MPa above clean initial value), element replacement is required.

Q6: Can the LYC purifier be used while the hydraulic system is running?

A: Yes. The purifier supports bypass (offline) filtration—connect it to the hydraulic system's return or suction line while 

equipment continues normal operation. This is the most common application mode.

Q7: What is the noise level during operation?

A: The LYC series is designed for low noise operation. Typical noise levels are below 75 dB(A) at 1 meter, making it suitable 

for indoor workshop environments.

Q8: What maintenance is required for the LYC oil purifier?

A: Regular tasks include monitoring differential pressure, replacing filter elements when indicated, cleaning the frame 

and casters, and inspecting hoses and electrical connections. No specialized maintenance is required.

Q9: Can the purifier handle high-viscosity oils?

A: The LYC series is optimized for conventional hydraulic oil viscosity (ISO VG 32–68). For higher viscosity oils, please consult

 our technical team for pump and motor sizing adjustments.

Q10: Does the purifier damage oil additives during filtration?

A: No. The filtration process is purely physical—solid particles are captured by the filter media without affecting the chemical

 structure of the oil. Additives remain intact.

Q11: What is the typical flow rate of the LYC purifier?

A: Flow rates vary by model. Standard LYC models range from 25 L/min to 100 L/min. Please refer to specific model datasheets

 for exact ratings.

Q12: Are there explosion-proof versions available?

A: Yes. Explosion-proof versions with EX-rated motors and electrical components are available upon request for hazardous 

environments (oil fields, chemical plants, etc.).

Q13: What spare parts should I keep in stock?

A: We recommend keeping a complete set of replacement filter elements and spare inlet/outlet hoses. Additional O-ring

 seal kits are also recommended for longer-term inventory.

Q14: Do you offer custom configurations for non-standard applications?

A: Yes. We offer custom flow rates, filtration precision, power supply configurations, and material options. Please provide

 your application requirements for a tailored solution.
