Description

Fume and Smoke Extraction System

The HJ3100 fume extraction unit is designed expressly for use at
soldering stations, extracting the contaminated air directly at the
source.

The HJ3100 is a high-mass flow, low vacuum system. Contaminated air is
captured from the workplace surrounding the soldering station by the
hood or hoods, and transferred to the HJ3100 unit by flexible or rigid
ducts.

Inside the unit, two filters, comprising three stages of filtering,
remove the contaminants from the air. The purified air is then
returned to the area where the HJ3100 is located.

The pre-filter is made of a treated polyester material that removes
coarse particles, such as dust, thus extending the life of the main
HEPA filter. The HEPA (High Efficiency Particulate Air) filter
consists of a pleated fiberglass paper medium, providing the greatest
amount of surface area within the volume of the filter case.

The standard filters used in the HAKKO HJ3000-series fume extractors
contain an activated carbon element built into the filter. This filter
is designed to last the life of the main HEPA filter. Carbon filters
have absorption ratings of 80-85%.

Efficiencies of the various HEPA/carbon filters for the HJ3100 are
greater than 98% at 0.3 microns. All tests per the DOP test as
stipulated in MIL-Std-282.

A wide range of accessories are available.


Filtering Stages

The Hakko filtering process supports three stages of filtering.

The pre-filter removes course particles, such as dust, which may be
suspended in the air. This extends the service life of the HEPA
filter.

The main HEPA/Carbon filter, then purifies the air in two ways. As the
HEPA filter removes particles as small as 0.3 micron, the carbon
filter absorbs gases and odors from the filtered air.

Another larger carbon filter then absorbs more gases and odors from
the air.
