Hydraulic Oil Filter Element Huahang Filter Manufacture

Products Description

The Hydraulic Oil Filter Element is a high-performance replacement cartridge designed for hydraulic and lubrication systems requiring reliable particulate removal. With its compact yet robust dimensions , this element delivers efficient contamination control in a space-saving package, making it ideal for equipment where standard-sized elements cannot fit yet high filtration performance is still required.

This filter element is engineered to effectively remove solid particles, metal wear debris, and gelatinous contaminants from hydraulic fluids, ensuring clean fluid circulation, optimal system performance, and extended equipment life. The pleated filter material structure dramatically increases effective filtration area within the 155×240 envelope, providing high dirt-holding capacity and low pressure drop while maintaining a compact overall size.

Features

High-Precision Glass Fiber Media: Premium multilayer inorganic glass fiber (borosilicate) media with a graded density depth filtration structure — larger particles captured on the outside, finer contaminants trapped closer to the core. The depth mechanism provides up to 3–5× the dirt-holding capacity of standard cellulose elements, significantly extending service intervals .

High Net Area & Low Pressure Drop: The special folded (corrugated) design effectively increases the filtration area while maintaining a compact overall size, resulting in high flow rates with minimal resistance. Low initial clean pressure drop reduces pump energy consumption and operating costs .

Pressure Differential Withstand: Conventional filter elements can withstand a differential pressure of 0.35-0.4 MPa, while special high-pressure filter elements can withstand system pressures of 32-42 MPa.

Excellent Fluid Compatibility: Compatible with general hydraulic oils, phosphate ester hydraulic fluids, water-glycol emulsions, emulsified oils, and lubricating oils. Also suitable for fuels and flame-retardant synthetic fluids, making the element versatile across diverse applications .

FAQ

Q: Can you manufacture a filter that matches the performance of my original OEM element?
A: Yes. Our goal is to meet or exceed the original OEM specifications for filtration efficiency, dirt-holding capacity, pressure drop, and structural integrity.

Q: How do I store spare custom filter elements?
A: Store in a cool, dry environment away from direct sunlight, extreme temperatures, and chemical fumes. Keep in original packaging until ready for installation to prevent pre-contamination.

Q: How do I ensure proper fitment when ordering?
A: To ensure exact fitment, we recommend:

Providing the original OEM part number from your existing filter element
Measuring the outer diameter , height , and inner diameter
Confirming the end cap configuration (open/open, open/closed) and seal type (O-ring, gasket)
Identifying the filter type (return line, pressure line, or suction line)
Specifying the required filtration rating and media type

Our engineering team can assist with cross-referencing to ensure perfect fitment.

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.
