THE LIMITATIONS OF TRADITIONAL FILTER BAGS:WHY PROCESS UPGRADES ARE CRITICAL?

The LOONG FILTRATION’s HFD Series Pleated Filter Bag is engineered for high-standard industrial filtration. It skillfully combines the high flow rate of large-capacity cartridges with the easy installation of traditional filter bags. This patented design allows for seamless integration into existing bag filter housings, making it the ideal solution for dramatically improving filtration efficiency.

I. The Limitations of Traditional Filter Bags:

Low Retention Efficiency: Unstable filtration results often fail to meet the requirements for precision filtration, especially with complex media.
Limited Filtration Accuracy: Conventional filter bags frequently fall short of the necessary absolute filtration ratings, impacting quality control in pharmaceutical and life science sectors.
Poor Dirt Holding Capacity (DHC): Frequent filter changes lead to increased operator workload and significantly drive up both material consumption and maintenance costs.

II. LOONG Filtration's HFD Series: Bag Pleated High Flow Cartridge

Through innovative, patented design, the LOONG Filtration HFD Series Pleated Filter Bag overcomes all the inherent drawbacks of traditional filter bags, delivering revolutionary performance improvements:

1. Superior Dirty Holding Capacity and Absolute Accuracy

Feature	Advantage	Technical Metrics
Exceptional Dirt Holding Capacity (DHC)	Unique pleated structure dramatically extends the service life of the filter element.	Dirty Holding Capacity is up to 10 times greater than standard filter bags.
Increased Filter Area	Maximizes effective filtration area, resulting in higher throughput and lower pressure drop.	Filter surface area is 4 times greaterthan standard filter bags.
Absolute Filtration Rating	Achieves industry-leading pore sizes, meeting the most demanding process requirements.	Capable of 0.1 um absolute filtration rating.
Inside-to-Outside Flow	Contaminants are reliably trapped within the filter element, eliminating the risk of cross-contamination during change-out.	Ensures the purity of both the process media and the operating environment.

2. Seamless Compatibility and Extreme Convenience

Plug-and-Play: The interface and installation method are fully identical to traditional filter bags, requiring no modification to existing bag filter housings or additional operator training.
Efficiency Boost: Simplified installation and maintenance steps reduce operation time by 50%, significantly enhancing on-site work efficiency.
Broad Compatibility: Suitable for various chemical solvents and process fluids, offering a perfect drop-in replacement for major international brands (e.g., PXXX, EAXXX).

3. Support for Graded Filtration Ratings

The Pleated Filter Bag offers two distinct filtration grades to meet diverse process requirements:

Nominally Rated: 11-100um, with a filtration efficiency of 90-95%
Absolute Rated: 1-20um with a filtration efficiency of 98-99%

III. The Ideal Choice for High-Value Industries

The HFD Bag-Type Pleated Filter's exceptional performance has made it indispensable across several critical industrial sectors:

Application Category	Specific Scenario	Core Value Delivered
Life Sciences	TCM Extract Filtration, Biologics Clarification, Animal Extract Filtration	High-efficiency clarification, ensuring the purity of active ingredients and meeting stringent biopharmaceutical standards.
Fine Chemicals	API Pre-filtration, Solvent Filtration, Pre-filtration for Formulations	Extends the service life of downstream fine filters and ensures the stability and reliability of the formulation process.
General Industrial	Water Treatment, Chemicals, Paints and Varnishes, Metal Cleaning, Petrochemicals	Provides a cost-effective, high-DHC filtration solution that reduces overall operating expenses.

The LOONG Filtration’s HFD Series Bag-Type Pleated Filter Element represents a significant step forward in industrial filtration technology. It is more than just a high-performance high-flow cartridge; it is a convenient pathway to achieving process optimization. For companies seeking an efficient, cost-saving, and easy-to-install filtration solution, the HFD filter element is the high-value choice to replace traditional filter bags and international brand equivalents.
