High Efficiency Portable Double Cartridge filter welding fume extractor
* Operating Principle:
It is equipped with three layer filter system
1, under the help of the fan device, the welding fume is sucked into inlet through sucking hood. There is the flame arrester in the inlet, so the spark can be blocked here, the left fume and dust is sucked into gravity separator, and then the bigger particles firstly descend into dust bag.
2, the smaller particles are arrested in the surface of core filter. The cleaner gas then flow into clean room after being purified by core filters.
3, in clean room, the clean gas is then further purified by active carbon. At last, the gas meets the required standards and enters into air or other required room.
**The basic Stage Filtration Process about the welding fume extractor
Stage 1: Air passes trhough the pre-filter fire-proof net.
Stage 2: Air passes through a second pre-separator to further reduce medium to heavy particulate matter.
Stage 3: Air passes through the LongLife-H filter where welding fume particles are captured and deposited.
Stage 4: Activated carbon filter will help prevent or neutralize the release of odors back into the environment.
