1. Product Definition and Core Technology
The high-flow water filter element is a filter element designed for high-flow and high-pollution load scenarios. It adopts a folded filter material structure and a high-strength support skeleton to significantly improve the filtration efficiency and pollution holding capacity. Its core technologies include:
- Pleated design: Through precision folding technology (such as fan-shaped pleats), the filtration area is expanded to 3-5 times that of traditional filter elements (the area of a single filter element can reach 30-40㎡).
- Composite filter material: Made of polypropylene (PP), glass fiber, polyethersulfone (PES) and other materials, it has both high-precision interception and corrosion resistance.
- Wide flow channel support: internal PP skeleton support to ensure structural stability under high flow, pressure difference ≤0.2MPa.
2. Core parameters
| Parameters | Index |
| Flow range | 10-60m³/h (single) |
| Filter accuracy | 1-100μm (customization supported) |
| Temperature resistance | PP material: ≤80℃; glass fiber material: ≤121℃ |
| Pressure difference | ≤0.3MPa |
| Life | 3-6 months (depending on water quality) |
| Interface type | 222/226 chuck type, threaded type |
3. Technical advantages
- High flow and low resistance: The flow rate of a single filter element reaches 60m³/h, which can replace multiple traditional filter elements, reducing the equipment volume and the risk of leakage at the connection point.
- Long life and low cost: Deep gradient filtration structure, the dirt holding capacity is increased by more than 50%, and the replacement frequency is reduced to 1/3 of the traditional filter element.
- Wide adaptability: Excellent acid and alkali resistance and oil resistance, suitable for a variety of media such as petrochemical wastewater, cooling water, organic solvents, etc.
Quick maintenance: Modular design, support online replacement, downtime is shortened to less than 10 minutes.
4. Main application areas

5. Comparison with traditional filter elements
| Comparison items | Large flow filter element | Traditional filter element (PP meltblown) |
| Single flow | 60m³/h | 2-4m³/h |
| Filtration area | 30-40㎡ | 0.5-1.5㎡ |
| Replacement frequency | 3-6个month | 1-2个month |
| Comprehensive cost | Save more than 40% of maintenance costs | High consumables cost, frequent downtime |
6. Selection and maintenance recommendations
- Selection points
Highly corrosive media: glass fiber or PES materials are preferred, resistant to acid, alkali and organic solvents.
High temperature conditions: Use glass fiber filter elements with a temperature resistance of 121°C to avoid thermal deformation.
High precision requirements: Combine with gradient filtration solutions (such as 100μm→50μm→10μm). - Maintenance strategy
Monitor the inlet and outlet pressure difference and replace it in time when it exceeds 0.2MPa.
Reverse flushing regularly (applicable to washable filter elements) to extend service life.
7. Industry Trends
- Intelligent Upgrade: Integrate pressure sensors and Internet of Things (IoT) modules to achieve filter life prediction and remote alarm.
- Green Materials: Develop degradable filter materials (such as bio-based PP) to reduce the environmental impact of discarded filter elements.
- Large flow water filter elements have become core components in the field of industrial water treatment due to their high efficiency, durability and low consumption.
