The QINFENG Valve Difference
Multi-Layer Filtration Architecture
Multi-Layer Filtration Architecture
Protection, filtration, dispersion, and dual support layers — each performing a specific function. Smooth mesh pores enable uniform filtration precision with high structural rigidity.
Regenerative Filtration Performance
Regenerative Filtration Performance
Unlike single-layer screens that fail within three months, the smooth-pored sintered mesh supports effective backwashing. Designed for repeated long-term use in continuous cooling operations.
Maintenance-Optimized Access
Maintenance-Optimized Access
Quick-release clamp design — open, remove, clean or replace, reassemble. No need to disconnect piping. Minimizes system downtime during routine filter service.
Cleanroom Assembly
Cleanroom Assembly
All filter elements assembled in a controlled cleanroom environment. Strict particulate control ensures every filter arrives contamination-free — ready for high-purity coolant service.

What is a five-layer sintered mesh filter and how does it work?

 
 

Five-layer sintered mesh consists of protection, filtration, dispersion, and dual support layers. Surface filtration with smooth mesh pores enables uniform precision filtration with high structural rigidity.

How does backwashing extend filter service life in cooling systems?

 
 

Smooth mesh pores allow effective reverse-flow cleaning that removes trapped particulates. Unlike single-layer screens that fail within three months, sintered mesh filters can be backwashed and reused repeatedly.

Where should filters be installed in a liquid cooling loop?

 
 

Install upstream of CDU plate heat exchangers to protect microchannels from particulate fouling, and in main distribution piping to prevent debris accumulation in cooling channels.

What is the advantage of a quick-open filter design?

 
 

Quick-release clamp lid allows fast element access without pipe disassembly. Open the housing, remove the element, clean or replace, and reassemble — minimizing system downtime during routine maintenance.
