High flow filter cartridges are large-diameter (typically 6 inches/152mm), pleated filtration elements designed to handle significantly higher fluid volumes than standard 2.5-inch cartridges. They are engineered to provide high-efficiency filtration in a compact footprint, making them a premium alternative to brands like PALL, 3M, and Parker.

They utilize a pleated media design that maximizes the available surface area within a single element. Fluid flows from the inside to the outside (or outside to inside, depending on the design), trapping contaminants within the deep pleats while allowing high volumes of clean liquid to pass through at low differential pressure

LOONG Filtration provides standard industrial lengths including 20, 40, and 60 inches. The typical diameter is 6 inches (152mm), allowing a single cartridge to replace multiple standard-sized elements. Also LOONG Filtration support customization for batch orders.

1. Large Surface Area: Pleated construction provides superior dirt-holding capacity.
2. High Flow Capacity: Capable of handling up to 500 GPM (114 m3/h) per 60-inch element
3. Robust Construction: Usually made of polypropylene or glass fiber for broad chemical compatibility.
4. O-ring Sealing: Ensures 100% bypass-free filtration.

Compared to bag filters, high flow cartridges offer higher filtration efficiency and longer service life due to their pleated structure. While bag filters are suited for coarse filtration, high flow cartridges provide absolute-rated precision, lower change-out frequency, and reduced disposal costs.

1. Reduced Footprint: Smaller filter housings are required to achieve the same flow rate.
2. Lower Maintenance Costs: Fewer cartridges mean faster change-outs and reduced labor.
3. High Dirt-Holding: Extends the interval between replacements.
4. Cost-Effective: Lower total cost of ownership compared to traditional multi-cartridge systems.

They are widely used in high-volume industrial applications including Reverse Osmosis (RO) pre-filtration, seawater desalination, power plant water treatment, petrochemicals, and large-scale food and beverage processing.

By removing fine particulates and suspended solids, they prevent the fouling of expensive RO membranes, protect high-pressure pumps from abrasion, and ensure the longevity of downstream sensitive instruments.

They effectively remove suspended solids, sand, silt, rust, scale, and organic debris. Depending on the micron rating (from 0.5μm to 100μm), they can capture fine microbial cysts or coarse sediments

Fluid Compatibility: Ensure the material (PP, GP, PBT, etc.) matches your chemical requirements.

Micron Rating: Choose the precision based on downstream equipment sensitivity.

Flow Rate: Calculate total flow to determine the number and length of cartridges needed.

Operating Conditions: Consider temperature and maximum pressure drops.

Replacement is typically recommended when the differential pressure reaches 2.4 bar (35 psi). Regular monitoring of pressure gauges ensures optimal performance and prevents bypass

Maintenance: Monitor pressure drop consistently; do not exceed recommended flow rates.

Storage: Store in a cool, dry place in original packaging to prevent contamination and UV degradation.

Yes. Their design often features an ergonomic handle and a simple "twist-lock" or slide-in mechanism, allowing a single operator to replace a cartridge in minutes without special tools.

Yes, because one high flow element can replace up to 20-50 standard cartridges, it significantly reduces plastic waste and the volume of spent filter media destined for landfills.

LOONG Filtration products are manufactured following strict ISO9001 quality management systems and utilize FDA/USP-listed materials for different applications, ensuring safety and performance consistency.

Yes. We offer customized micron ratings, specific lengths, and various O-ring materials (EPDM, Viton, Silicone) to meet unique industrial requirements and ensure 1:1 compatibility with existing PALL or 3M housings
