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 FA5-2 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 FA5-2 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# FA540B;
“HEPA” for part# FA500). The bar graph will increase in 20% increments until the filter is “loaded”. Red lights will
indicate that a filter change is necessary.
The FA5-2 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 FA5-2 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 # FA540B
– 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 4-6
months.
Part # FA500
– HEPA Filter
The HEPA filter is 99.97% efficient in removing particles as small as 0.3
from an airstream.
Particles of this size are respirable and can cause significant respiratory problems.
