Multi-Stage Filtration System Improves Purification Efficiency


Release time:

2025-08-29

Some range hoods adopt a multi-stage filtration system. First, a honeycomb filter screen initially intercepts large oil particles, then a dynamic oil collection screen further filters smaller particles. Finally, a centrifugal wind wheel with a nano-coating separates the remaining tiny oil particles using centrifugal force during high-speed operation. At the same time, the nano-coating can also prevent oil stains from adhering. This not only improves purification efficiency but also realizes that the inner cavity does not need to be disassembled for cleaning for many years, reducing the user's maintenance cost.
