CONTROLS
On/Off Switch
Simple one touch controls – The green light above the POWER button will illuminate confirming power to the
unit.
Blower/Fan
The FA2 utilizes a variable speed blower with 8 speed settings. Press the up /down arrows to increase and
decrease the blower speed. Blower gradually increases in speed as “Up” arrow is pressed - some slight delay is
normal operation. Speed is indicated by the bar graph located above “BLOWER” label. A green light will indicate
that the blower is operating – no light indicates a blower failure or loss of power.
Filter monitoring
The FA2 utilizes independent pressure differential switches to monitor the status of each particulate filter (the
Pre-filter and the HEPA filter). Filter status is indicated by the corresponding bar graph (“PRE” for part# FA140B-
2; “HEPA” for part# FA100). The bar graph will increase in 20% increments until the filter is “loaded”. Red lights
will indicate that a filter change is necessary.
The FA2 contains a VOC sensor to detect odors/gases in the exhaust stream. The system continually monitors
the exhaust stream which is indicated on the bar graph labeled “GAS”. When the gas/odor filter becomes
saturated, and breakthrough of the VOC occurs the “GAS” warning light will illuminate.
GENERAL FILTER CARE
Fumex FA2 air purifiers feature a multi-stage filtration system designed to remove a wide range of pollutants
from the process plume in an extremely efficient, and cost-effective manner. Once the warning lights illuminate,
filters should be checked, and clogged filters replaced.
S T A N D A R D F I L T E R S:
Part # FA140B-2 – Pre-filter Assembly
The pre-filter assembly is the first stage in the filtration process. Unique design minimizes operator/maintenance
personnel exposure to contaminants.
Replacement:
Filter life is highly dependent on the amount and size of the captured particulates. Average service life is 1-3
months.
