Durable Double-Layer Non-Woven Pocket Air Filter Media
Designed for the toughest industrial air intake systems, our Pocket Filter Media features a reinforced double-layer composite structure. Whether it’s for an automotive paint booth or a pharmaceutical cleanroom, these filters provide stable performance. The leak-proof, trilateral-sealed design prevents fiber shedding and air leakage, ensuring that your secondary filtration stages remain protected from heavy dust loads.
Product Key Features
Structural Stability: The firm design prevents the pockets from sagging or fluttering, which reduces the risk of mechanical failure or particle bypass.
Versatile Filtration Grade: Excellent as a pre-filter or secondary filter (G4/F5/F6/F7 compatible) for a wide range of industrial standards.
Cost-Effective Maintenance: The ability to withstand multiple wash cycles and its high durability make it the most cost-efficient choice for large-scale ventilation.

Material & Craftsmanship
Fiber Technology: High-strength synthetic fibers that maintain their shape and efficiency after cleaning.
Frame Construction: Rigid frame support using high-grade galvanized steel or lightweight aluminum alloy.
Operating Conditions: Tested for peak performance at 80% relative humidity, ensuring reliability in humid industrial processing zones.
Applications
The Durable & Customizable Pocket Filter Media is the preferred choice for heavy-duty industrial environments and specialized engineering projects:
Automotive Paint Booths: Engineered to withstand constant air pressure while capturing fine overspray, ensuring the structural stability required for high-quality finishing.
Heavy Industrial Plants: Ideal for steel mills, cement factories, and mining facilities where high dust concentrations demand a high-strength pre-filtration solution.
Custom HVAC Retrofits: Perfectly suited for older ventilation systems or unique architectural designs that require non-standard pocket sizes or specific frame depths.
High-Pollution Urban Zones: Used in commercial buildings located in areas with high PM10/PM2.5 levels, providing a long-life barrier that reduces the frequency of filter changes.
OEM/ODM Projects: Designed for filter manufacturers who need a reliable composite bag filter material that can be tailored to their own branded specifications.

Frequently Asked Questions
Q1: Can I order this pocket filter media in custom dimensions?
Absolutely. We specialize in customization. Whether you need specific pocket depths, a particular number of bags, or unique header sizes for aluminum or galvanized frames, we can tailor the media to meet your exact engineering requirements.
Q2: What makes your “Double-Layer” structure more durable?
Our media features a reinforced double-layer composite structure. The outer layer captures larger particles while the inner layer provides fine filtration and structural support. This prevents the media from stretching or “ballooning” under high pressure, ensuring stable performance over time.
Q3: How does the “firm design” prevent mechanical failure?
Standard bags often flutter or sag, which leads to friction and eventually tears. Our firm, leak-proof design uses breadthwise sewing and thermoplastic sealing to keep the pockets rigid and aerodynamic. This reduces mechanical stress and prevents air leakage.
Q4: Is this media suitable for protecting high-end secondary filters?
Yes, that is one of its primary roles. By capturing the bulk of heavy dust loads, our high-strength pre-filter media prevents your expensive secondary filters (like HEPA) from clogging prematurely, significantly extending the overall life of your filtration system.
Q5: What is the maximum humidity and temperature this media can handle?
Our Pocket Filter Media is built for toughness. It is tested to maintain its structural stability and filtration efficiency in temperatures up to 80°C and relative humidity levels of 80%, making it reliable for almost any industrial climate.
