Products Description

This 316 SS Polymer Melt Filter Element is precision-engineered from high-grade 316 stainless steel through advanced sintering or multi-layer mesh bonding, creating an absolute-rated porous barrier capable of withstanding the extreme conditions of molten polymer filtration—high pressure, elevated temperature, and corrosive polymer additives or by-products.

Designed to capture and retain carbonized particles, gel specks, foreign contaminants, filler agglomerates, and degraded polymer residues, this filter is essential for producing defect-free fibers, films, sheets, and high-quality molded components. Its robust all-metal construction ensures zero media migration, exceptional structural integrity under pulsating pump pressure, and the ability to be fully regenerated through controlled pyrolysis (burn-out) cleaning, offering a permanent solution that dramatically reduces consumable costs and production waste. The 316 stainless steel composition provides superior resistance to pitting and crevice corrosion caused by chlorides, acidic breakdown products, and aggressive cleaning agents, making it the material of choice for reliable, long-term service in the most demanding polymer processing environments.

Features

316 Stainless Steel Construction: Offers excellent resistance to corrosion from polymer additives, heat degradation by-products, and aggressive cleaning agents, ensuring long-term durability and preventing product contamination.
High Dirt-Holding Capacity & Optimized Flow: The depth-type design of sintered metal or layered mesh provides substantial contaminant loading before necessitating a change, stabilizing pressure increase and extending production runs.
Fully Regenerative & Reusable: Can be cleaned multiple times via professional burn-out ovens or fluidized bed cleaners, restoring near-original performance and providing the lowest possible filtration cost per ton of polymer processed.
Maintains Process Stability: By providing consistent filtration efficiency, it helps maintain stable head pressure and throughput, which is critical for dimensional consistency in fibers, films, sheets, and profiles.

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.
