Laminated Polyester Fabric Air Filter Cartridge 130x210

Products Description

The laminated polyester fabric air filter cartridge 130×210 is a high-performance cylindrical filter cartridge designed for industrial dust collection and air purification systems. With dimensions of 130mm in length and 210mm in outer diameter, this filter cartridge delivers exceptional dust removal performance through its advanced laminated media construction.

Unlike conventional depth filtration filters, this cartridge features a robust polyester felt base media that is permanently bonded with a micro-porous PTFE membrane. This lamination process creates a surface filtration mechanism—a significant upgrade from traditional depth filtration. Instead of allowing dust to penetrate deep into the media fibers, the ultra-smooth membrane acts as a precise sieve, capturing the vast majority of fine particles directly on its surface.

Choose PTFE when: Your application involves sticky, hygroscopic, or fine dusts that blind standard media; chemical exposure (acids, alkalis, solvents); high humidity or moisture; or where consistent low pressure drop is critical.
Choose Polyester when: You need standard industrial dust collection without chemical or moisture challenges, and cost is a primary consideration.
Choose Fiberglass when: You need high-temperature resistance (>150°C) or HEPA-grade efficiency.

FAQ

Q: What is the difference between laminated polyester and standard polyester filter media?
A: Standard polyester filters use depth filtration, where dust penetrates into the media fibers, increasing pressure drop and making cleaning difficult. Laminated polyester features a PTFE membrane bonded to the surface, creating surface filtration that traps dust on the surface for easy release, higher efficiency, and longer service life.

Q: How does the pleated design improve filtration?
A: The pleated design increases the effective filtration surface area within the same cartridge volume, allowing the filter to capture more particles without obstructing airflow. This results in higher dust-holding capacity and longer service life.

Q: Is this cartridge resistant to chemicals?
A: Yes. The laminated polyester fabric has excellent chemical stability and hardly reacts with any substance, exhibiting extraordinary corrosion resistance. Polyester coated filter cartridges also have resistance to certain chemicals.

Q: Can you customize the dimensions and filtration specifications?
A: Yes. We offer full customization services including custom dimensions, filtration efficiency, anti-static treatment, oil-proof/water-proof treatment, and end cap configurations. Please provide your specific requirements or drawings for a custom quotation.

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.
