Introduction
For over 16 years, LEFILTER has been a trusted manufacturer of high-quality, affordable filter cartridges and filtration systems, offering premium alternatives to global brands like PALL, HYDAC (Hengstler), MAHLE, Internormen, and Parker. Today, we take pride in our advanced self-cleaning filters, which are 100% manufactured in our own facility in Xinxiang, Henan, ensuring competitive pricing, rapid production, and short lead times—key advantages that meet the stringent demands of industrial clients worldwide.
The Growing Need for Efficient Water Filtration
Industrial water treatment is critical in sectors such as manufacturing, power generation, chemical processing, and HVAC systems. Contaminants like suspended solids (SS), particulate matter, scale, and algae can severely impact equipment performance, leading to higher maintenance costs, reduced efficiency, and even system failures. Traditional filtration methods, such as manual cleaning or disposable cartridge filters, often result in downtime, labor-intensive maintenance, and increased operational expenses.
This is where LEFILTER’s self-cleaning filters excel. Designed for industrial water, cooling water, process water, and recirculating systems, our filters automatically remove impurities without interrupting operations, ensuring consistent water quality and system longevity.
LEFILTER’s Self-Cleaning Filtration Solutions
Our self-cleaning filters are engineered for high-flow, high-efficiency filtration with minimal maintenance. Key features include:
1. Advanced Filtration Technology
Precision Filtration (50-3000 μm): Removes suspended solids, rust, sediment, and algae from water, protecting downstream equipment.
Automatic Backwashing: Utilizes differential pressure (ΔP) or timed control to trigger cleaning, ensuring uninterrupted operation.
Sturdy Construction: Made from 304/316L stainless steel for corrosion resistance in harsh environments.
2. Industrial Applications
Cooling Water Systems: Prevents heat exchanger fouling, reducing energy consumption by up to 15%.
Process Water Filtration: Ensures clean water for production lines, minimizing contamination risks.
Wastewater Reuse: Extends water lifecycle by removing fine particulates before discharge or recycling.
3. Cost & Efficiency Benefits
Reduced Downtime: Eliminates manual cleaning, cutting maintenance costs by 80%.
Energy Savings: Low-pressure drop (≤0.1 MPa) reduces pump workload.
Long Service Life: Robust design ensures years of reliable operation.
Case Study: Cooling Water Filtration in a Chemical Plant
A chemical plant in Henan previously used sand filters + manual mesh cleaning, suffering from:
1. Frequent clogging (SS ≤200 mg/L)
2. Monthly shutdowns for cleaning
3. High labor costs
After switching to LEFILTER’s self-cleaning filters, the plant achieved:
1. SS reduction to ≤10 mg/L (95% removal rate)
2. Cleaning intervals extended from monthly to quarterly
3. Annual savings of $155,000 (reduced labor, water, and energy costs)
Why Choose LEFILTER?
1. Factory Direct Pricing: No middlemen mean lower costs for clients.
2. Fast Production & Delivery: 15-day lead time for standard models.
3. Custom Solutions: Tailored designs for unique flow rates, pressures, and media.
4. Global Compliance: Certifications include ISO 9001, CE, and RoHS.
Conclusion
As industries worldwide seek sustainable, low-maintenance water treatment solutions, LEFILTER’s self-cleaning filters stand out as a smart, cost-effective choice. By combining automation, durability, and affordability, we help businesses enhance efficiency, cut costs, and protect critical equipment.
