Fiberglass Air Filter Element 20.8x39

* Seamless Fusion Construction: Every component is joined using a seamless fusion method. This eliminates weak points that cause leaks or structural failure in lesser filters, and ensures the element holds up under pressure.

* Progressive Density Media Structure: The fiberglass media density increases from the outer layer inward. Larger particles get trapped on the surface; smaller ones get caught deeper in the media. This layered approach delivers high efficiency, low flow resistance, and impressive dust-holding capacity all at once.

* Durable 316 Stainless Steel: Both the inner spring and outer punched plate are 316 stainless steel. That means no rust, no corrosion, and no degradation even in humid or chemically harsh environments.

* Low Pressure Drop: Thanks to the progressive density design and optimized pleating, air moves through the element freely. Your system doesn’t have to work harder just to pull air through a clogged filter.

* High Dust-Holding Capacity: The combination of fiberglass media and deep pleats means this element holds more dirt before it needs cleaning or replacement. Longer service intervals, less frequent maintenance.

The fiberglass air filter element is built for industrial environments where clean air isn’t a luxury—it’s a requirement.

* Machine Tool Industry: About 85% of machine tool transmission systems run on hydraulics—grinders, milling machines, planers, drawing machines, presses, shears, and combination machine tools all rely on clean hydraulic fluid. This filter keeps the fluid clean.

* Metallurgical Industry: Electric furnace controls, rolling mill systems, blast furnace controls, strip deviation correction, constant tension devices—these systems fail fast when contaminants get in. The 20.8x39 element stops them before they cause trouble.

* Engineering & Construction Machinery: Excavators, wheel loaders, truck cranes, crawler dozers, graders, vibrating rollers—these machines eat dirt for breakfast. Their hydraulic systems need protection that holds up to the abuse. This filter delivers.

* Agricultural Machinery: Combine harvesters, tractors, plows—modern farm equipment runs on hydraulics too. Dust and debris from the field don’t stand a chance against fiberglass filtration.

Xinxiang City Huahang Filter Co., Ltd. is a professional industrial filter manufacturer based in Henan, China, established in 2009. The company integrates design, production, sales, and service under one roof, specializing in hydraulic oil filters, air filters, water filters, polymer filters, sintered filter elements, coalescers, and separators. Huahang operates its own state-of-the-art production facility and holds ISO 9001 quality certification as well as CE certification, which means every filter that leaves the factory has been tested and verified to meet rigorous standards. 

1. Own Factory, Not a Trader. Huahang isn‘t a middleman. They manufacture everything in-house, which gives them absolute control over quality, lead times, and pricing. When you need a filter, they make it—they don’t just repackage someone else‘s.

2. Advanced Equipment, Precision Manufacturing. The company continuously invests in automated production lines—corrugation machines, gluers, welding equipment, and precision testing gear. This isn’t a garage operation. It‘s a modern factory built for consistency at scale.

3. Professional Engineering Team. Huahang employs experienced R&D engineers, production technicians, and quality inspectors who know filtration media inside and out. They don’t just follow spec sheets—they solve problems.

4. Multi-Stage Quality Control. Every production line has stringent checkpoints: IQC (incoming raw material), IPQC (in-process), FQC (final), and OQC (outgoing). Before any filter ships, it‘s been tested for dimensional integrity, filtration efficiency, and structural durability.

5. Scale Production, Stable Supply. Huahang’s combination of advanced equipment and efficient management means they can handle both standard orders and custom jobs without missing deadlines. When your production schedule depends on filter deliveries, that matters.

Q: Is this filter washable and reusable?
A: Yes. The metal folding frame is designed for reuse, and the fiberglass media can be cleaned under proper procedures. However, after extended operation, the element will accumulate trapped impurities that cause pressure to rise and flow to decrease—at that point, cleaning is necessary. When cleaning, take care not to deform or damage the media structure.

Q: What filtration efficiency can I expect?
A: The progressive density glass fiber media is designed for high-efficiency particulate capture. Specific efficiency ratings depend on the micron rating of your particular application, but the media structure is capable of capturing fine particulates while maintaining low resistance to airflow.

Q: Can Huahang make a custom size if this one doesn’t fit my equipment?
A: Absolutely. Custom manufacturing is a core service. Huahang works from your drawings, samples, or specifications to produce filters in non-standard dimensions, with custom media, modified end caps, or alternative frame materials.

Q: How do I know when to replace this filter element?
A: Watch for pressure drop increases and flow rate decreases. When the element has trapped enough contaminants, system pressure rises and flow drops. That‘s your signal that cleaning or replacement is needed. Regular inspection of the media for visible dirt accumulation also helps.

Q: Is Huahang ISO certified?
A: Yes. Huahang Filter holds ISO 9001 quality management certification and CE certification, verified by independent third-party auditors.
