GETTING STARTED
Initial set-up
1. Open all cartons and locate inlet, hose, hose clamps and wheels.Refer to Table 1 for the applicable part
numbers for your model.
2. Remove ALL filters and packing materials from cartons and the unit cabinet.
3. Place the unit on its side and install wheels in the bottom plate.
4. Attach the inlet to the top of the lid with the six screws provided.
5. Remove plastic wrap from gas/odor filter (refer to Table 1 for filter part numbers).
6. Place gas/odor filter into the bottom of the cabinet and secure with the provided threaded rod, retaining plate,
and wingnuts (NOTE: Pay attention to direction of airflow arrow).
7. Place the FX7 pre-filter on top of the gas/odor filter.
8. Close and latch the lid.
9. Attach power cord to the power receptacle located on the lower rear of the cabinet.
Locating the air cleaner
Placing the GS2-200 unit as close as possible to the pollution source reduces the amount of ducting needed,
reduces back-pressure, lowers power consumption, and improves overall performance. Placement should
minimize hose length and the number of bends. Use capture hoods with high efficiency entry whenever
possible. The unit exhausts through the bottom panel make sure to allow for adequate ventilation.
Inlet hose attachment
The GS2-200 unit ships standard with a 1 x 2”, 2 x 2” or 1 x 3” inlet. Attach flex hose over the metal air inlet tube
and tighten securely with the stainless-steel clamp. Connect the hose to a Fumex suction hood or place as close
as possible to the pollution source.
Electric power
GS2-200 series is manufactured with a universal blower/motor assembly (90-250/1/50-60) and must only use a 10-
Amp fuse. Default power cord/plug is US (120V). Contact Fumex for additional information or options.
Confirm that correct power supply is available.

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 GS2-200 unit utilizes a variable speed blower with three speed settings. Press the up and down arrow
buttons to increase/decrease blower speed. A green light next to the specific speed (Low, Med, or High) will
indicate speed setting. In the case of a blower failure, all 3 blower speed lights will flash. To reset the blower’s
internal thermal protection, disconnect the unit momentarily from its power source and reconnect. If the lights
continue to flash contact Fumex LLC. for replacement information.
Filter monitoring
The GS2-200 unit utilizes a pressure differential switch to monitor the status of the Pre-filter. The system
monitors across all filters simultaneously and the Red “FILTER” light will illuminate when the Pre-filter needs to
be replaced. The recommended procedure is to replace the Pre-Filter and then press the “FILTER RESET” button.
If the light remains illuminated or turns off and comes back on then contact Fumex for assistance.
The GS2-200 unit contains a VOC sensor to detect odors/gases in the exhaust stream. When the gas/odor filter
becomes saturated and breakthrough of the VOC occurs the “GAS” warning light will illuminate.
GENERAL FILTER CARE
Fumex’s GS2-200 air purifier features a multi-stage filtration system designed to remove a wide range of
pollutants from the process plume in an extremely efficient, cost-effective manner. The sytem utilizes a pressure
differential switch to indicate blocked / clogged filters. Once the warning lights illuminate, filters should be
checked and clogged filters replaced.
STANDARD FILTERS:
Part # FX7 – Polyester pre-filter
The disposable polyester pre-filter is the first stage of the filtration process. Its main function is to remove dust
particles 100µand larger in advance of the more expensive pleated panel filter.
Replacement:
The service life of the polyester pre-filter is determined by the type and volume of large particles collected.
Average service life is 4-6 weeks

Gas/Odor Filters
Most process plumes contain several gases, some odorous – some not, some toxic at elevated concentrations
– some completely harmless regardless of concentration. To ensure employee safety the type and
concentration of pollutants must be determined. Please contact Fumex Engineering for filter selection
assistance.
Part # FX1
Filled with virgin-grade activated carbon pellets and is UL Class 2 rated compliant. It will not produce flame
when attacked by flame and emits only negligible amounts of smoke.
Part # FX1K
Virgin-grade activated carbon specially treated to eliminate exothermal reactions.
Part # FX2
These filters utilize a blended activated carbon and activated alumina impregnated with KMnO4 filter to
capture and treat gases/odors. This combination of materials provides protection across a broad range of
gases commonly found in industrial manufacturing processes.
Part # FX4
Blend of FX1 with FX2 for broad spectrum gas treatment.
SELECTING GAS/ODOR ADSORBENT FILTERS
Media Selection and Service Life
Fumex offers different media types, each formulated to target the removal of various types of gas and odor.
Any of the following factors will impact service life and efficiency.
Concentration of the gas – higher concentrations improve capacity (increased pressure forces adsorption
deeper into the media).
Relative humidity – high RH substantially decreases capacity (except water miscible gases).
Temperature– high operating temperatures reduce efficiency and capacity and increase desorption.
Competitive adsorption – numerous gases confound capacity and efficiency estimates.
Exothermic Reactions
Certain gases such as ketones can undergo oxidation or other chemical reactions that can liberate hazardous
levels of heat in the presence of standard activated carbon. In the presence of such gases use only Fumex
FX1K adsorbent to eliminate this hazard.

GENERAL MAINTENANCE
1) The blower motor is a sealed unit, 24,000 hr. MTBF rated. It is permanently lubricated and does not require
oiling – keep it free of dust accumulations to prevent overheating.
2) Remove any loose accumulations of dust/debris from the air filter chamber periodically.
“This product employs overload protection (fuse). A blown fuse indicates an overload or short-circuit situation. If
the fuse blows, unplug the product from the outlet. Replace the fuse as per the user servicing instructions (only
10-Amp fuse) and check the product. If the replacement fuse blows, a short circuit may be present and the
product should be discarded or returned to an authorized service facility for examination and/or repair”.
Remote Interface and Connectivity Function
The GS2-200 unit can be supplied with an optional interface package providing remote start/stop and filter
monitoring capabilities (Part # FA228). Please see instructions below for Relay Activation/De-Activation
procedures and refer to the drawing in Figure 1 for remote connections.
WARNING
“To Prevent the Risk of Electrical Shock, Connect Remote Interface
Cable to 24v, Class 2 Power Supply Only”
