How cost-Effective Chinese(sffiltech) Automatic Filter Replacing European High-End Brand

One Real customer case:

A European engineering company was seeking a reliable and cost-effective alternative to a well-known German automatic back-flushing filter used in its industrial water treatment system.

Their previous supplier offered stable performance but at a very high price and long delivery time. The client wanted a replacement solution with equivalent quality, full documentation, and faster delivery for a cooling water filtration project.

Customer Requirements

Filtration medium: Process cooling water

Flow rate: Up to 150 m³/h per unit

Operating pressure: 6–10 bar

Filtration accuracy: 300 microns

Material: Stainless steel 304 / 316L

Flange standard: DIN PN16

Documentation required: Hydrostatic test report, welding qualification, strength calculation, and material certificates

SFFILTECH Solution

After detailed technical comparison, SFFILTECH proposed two customized automatic back-flushing filter models (BCM500 and BCM300), designed to match the client’s existing installation and piping configuration.

Both filters were equipped with:

Automatic backwashing function triggered by differential pressure sensors

PLC-based control system for fully automatic operation

Heavy-duty stainless steel housing fabricated according to EN and ASME standards

Complete quality documentation package, including:

Hydrostatic test report

Strength and pressure calculation

WPS/WPQR and welder certificates

EN 10204 3.1 material certificates

Final product inspection record

Results & Benefits

Cost Reduction: Saved not only 50% compared to the previous European brand

Shorter Lead Time: From 14–16 weeks down to 5–6 weeks

Reliable Operation: Stable automatic backwash cycle, no manual cleaning needed

Compliance: Accepted by EU engineering consultants after reviewing the document package

Customer Satisfaction: The user reported smooth operation and no clogging issues during the first 6 months of service

Conclusion

This project demonstrates how SFFILTECH’s Chinese-engineered automatic filter housing can successfully replace expensive European brands in demanding industrial applications — delivering the same performance, faster delivery, and much higher cost-efficiency.

SFFILTECH continues to support global partners in industrial water, oil, and process filtration projects, providing OEM-level engineering, documentation, and long-term service support.
