The unit is a Fume Purifying & Filtering System for cleaning of both
particles and gases. The unit is double fuming arms design and during
the process of soldering, laser marking, laser carving, printing etc., to
be used at filtrating the harmful substances, such as hydrocarbon,
cyanide etc.
For good efficiency, it designs a Triple-filter system: pre-Filter,
middle filter and main filter which including HEPA (high efficiency) filter
and gas filter. The pre-filter with large area ASHRAE and the middle
filter can filter the bigger powders for prolonging the main filter’s life.
The HEPA cleans the gas and powders filtering from the pre-filter and
then output them to the gas filter, which with the carbon and other
chemical combination, filters off the deleterious substance and then
outputs the clean air.
