Working Principle

The LYC-C100 Portable Oil Purifier operates through a straightforward, highly effective three-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 – Primary Precision Filtration (10–40μm): The oil passes through the first precision filter element, where graded-depth media removes fine particulate contaminants. Filtration accuracy can be selected from 10μm, 20μm, or 40μm based on application requirements.
Stage 3 – Secondary Precision Filtration (3–10μm): The oil then passes through the second precision filter element for final polishing. Available in 3μm, 5μm, or 10μm, this stage delivers ultra-fine particulate removal to achieve stringent cleanliness standards.
Water and Gas Removal: The filtration system also removes 100% of free water and over 80% of dissolved water, as well as 100% of free and entrained gases, ensuring comprehensive fluid conditioning.
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.

FAQ

Q1: What is the difference between LYC-C series and LYC-A/B series?
A: The LYC-C series features a fully enclosed box-type design that protects all components from external environmental contamination, making it suitable for high-cleanliness environments. It also offers higher flow capacity and three-stage filtration compared to the two-stage A series.

Q: What types of oil can the LYC-C100 filter?
A: The LYC-C100 is suitable for general hydraulic oil, water-glycol (BH), phosphate ester (V), lubricating oil, gear oil, transformer oil, diesel, and gasoline (explosion-proof version).

Q: When should I clean or replace the filter element?
A: Monitor the pressure gauge. When pressure reaches 0.39 MPa, the filter element is loaded with contaminants and requires cleaning or replacement. The recommended change-out differential pressure is 0.2 MPa.

Q: Does the unit have an optional integrated oil tank?
A: Yes. The LYC-C100L version features an integrated oil tank that allows oil from a reserve tank to be filtered through self-circulation before direct injection into the system.

FAQ

What is the difference between a standard filter and a custom filter?

Standard filters are mass-produced in fixed sizes and specifications, while custom filters are designed to match specific equipment dimensions, operating conditions, and filtration requirements. Custom filters improve sealing, efficiency, and service life.

How do I select the right filter for my application?

Filter selection depends on fluid or air type, particle size, flow rate, pressure, temperature, and compatibility with the system. Providing operating data helps ensure optimal filtration performance.

Will your replacement filter cartridges damage my equipment? Is the quality guaranteed?

Absolutely not. Our replacement filter cartridges strictly adhere to OEM dimensions, interfaces, and performance standards, using equivalent or superior filter materials, and have passed rigorous ISO testing and end-user validation. We provide a quality guarantee to ensure the safe operation of your equipment.

We don't have a specific model number, only operating condition requirements. Can you help us select a suitable model?

Yes, but you need to provide:

① the filtering medium (oil, gas, water, chemical liquid?);

② flow rate, pressure, and temperature;

③ required filtration accuracy;

④ connection type.

Our technical team will recommend the most economical solution for you.

How can I ensure that this filter element can be adapted to my device/system?

We have multiple ways to ensure compatibility:

Provide original filter element information: Please provide the brand, model, clear photos or detailed dimension drawings of your existing filter element (especially the interface type and size, length, outer diameter, inner diameter).

Provide equipment information: Tell us your equipment brand, model or application scenario, etc.

Contact us: Our technical team has rich experience and can quickly determine or design a fully compatible replacement filter element based on the information you provide. It is recommended that you contact us directly to obtain the most accurate adaptation plan.

How do you ensure the quality and performance of the filter element?

Quality is our lifeline. We insist on:

Strict material selection: Use high-quality raw materials that meet industry standards.

Advanced technology: Use automated or precision-controlled production processes.

Multiple quality inspections: Implement full-process quality inspections from raw material storage to finished product delivery (including size, sealing, filtration efficiency, integrity testing, etc.).

Performance testing: Key products will undergo actual working condition simulation testing.

Compliance with standards: Our production and products comply with [e.g.: ISO 9001].

Customized verification: For customized filter elements, we will confirm key performance indicators with customers and provide test reports (if necessary).

What is a dust collector filter used for?

Dust collector filters remove airborne dust and particulate matter from industrial processes such as welding, grinding, woodworking, and powder handling to protect equipment and improve air quality.

How often should dust collector filter cartridges be replaced?

Replacement depends on dust load, operating hours, and cleaning efficiency. A consistent increase in pressure drop is a common indicator that the filter needs replacement.

Can dust collector filters be cleaned and reused?

Many cartridge filters are designed for pulse-jet cleaning, but they are not permanently reusable. Over time, media fatigue reduces performance and replacement becomes necessary.

What micron rating is best for hydraulic oil filtration?

Common hydraulic filters range from 3 to 25 microns. The optimal rating depends on system sensitivity and manufacturer specifications.

What happens if a hydraulic oil filter is not replaced on time?

Delayed replacement can cause pressure loss, valve sticking, pump wear, and reduced system efficiency, leading to costly downtime.

Where are precision filters commonly used?

Precision filters are widely used in electronics manufacturing, pharmaceuticals, food processing, chemical processing, and high-purity fluid systems.

How does precision filtration affect system performance?

Precision filtration improves product quality, extends equipment life, and reduces unplanned downtime caused by contamination.

What is the difference between a coalescer filter and a separator filter?

They are two distinct technologies often used together to remove liquids from a gas or liquid stream. The key difference is their core function:

A Coalescer Filter merges tiny, invisible liquid droplets into large, heavy ones.

A Separator Filter catches and drains those large droplets from the flow.

How They Work:

Coalescer: The stream passes through a special media (like fine fibers). Microscopic aerosol droplets collide and merge (coalesce) into drops large enough to drain. It solves the problem of suspended mist.

Separator: The flow then enters a chamber with baffles or vanes. The now-large droplets hit the surfaces, fall out by gravity, and collect in a sump. It provides the final, clean separation.

Are stainless steel filter elements washable?

Yes, most stainless steel filter elements can be cleaned using backflushing, ultrasonic cleaning, or chemical cleaning methods.
