- Joint R&D by senior Chinese and German filtration specialists
- Full-chain delivery: process calculation, system design and control programming
Wall-flow filtration: a structural leap in efficiency
Each wall-flow element provides a matrix of parallel filtration channels. Compared with the surface filtration of conventional candle elements, it delivers 8–10× more filtration area per unit volume — making systems more compact and piping simpler.
Conventional candle element
CONVENTIONALSEPARATION wall-flow element
SEPARATION WALL-FLOW8–10×
More filtration area per unit volume; compact systems and a smaller footprint at high gas flow rates.
2× or more
A cyclonic inlet avoids direct impingement, markedly extending element life and protecting process continuity.
In-line
Automated online filtration and pulse cleaning, proven across more than a thousand systems.
30+ Years
Combined industry experience of our Chinese and German specialists, across three technology generations.
