1.6. Usage
The Fume Extraction System is a portable, two-station filtration system for the removal of fumes, light
dust or vapors at the work place. The filter set supplied with the filter unit depends on the model
ordered.
Model BVX-201 supplied with a pre-filter and a main filter. The main-filter is a combo-filter consisting
of a HEPA filter with an efficiency of 99.97% at 0.3 micron and an activated carbon filter. This model
is designed for applications such as solder fumes from solder irons, solder pots, etc.
Model BVX-203 supplied with a pre-filter and a deep-bed gas filter (activated carbon). This model is
designed for applications such as cleaning with solvents, conformal coating, etc.
WARNING!
Consult your “safety department” when using the unit on flammable gases. This unit is not explosion safe
and only used for the extraction of vapors, which have concentration levels well below the lower explosive
limits.

2. Description
2.1. Operating Elements and Construction
2.2. Theory of Operation
The efficient removal of hazardous fumes at your workplace is a two-step process: fume capture
and filtration. The filter unit is supplied with a set of filters already installed.
To capture the fumes, Metcal recommends use of optional exhaust arms and accessories
(purchased separately). The exhaust arms need to be set up properly (instruction supplied with
exhaust arm) and the nozzle positioned in a way to optimize the fume capture.
Air extracted from your work area will be purified when passing through the filters inside the unit
and then is returned into your work area.
Contact your local Metcal representative if there are any questions regarding the proper
selection of filters for your application.
When the filters are blocked, an alarm will start to sound. See section 5.4 for filter replacement
procedures.

4. Installation
Remove the Fume Extraction System from packing materials and place on the floor under workbench
or near your work area where fume extraction is required. Make sure you have access to the unit for
filter maintenance.

Connect the unit power cord into the outlet on the side of the system. Plug the power cord into a
grounded wall socket.
Warning!
To provide protection against the risk of electrical shock, connect to properly grounded outlets only.
Connect the unit to exhaust arms (optional) per installation instructions. To power up system, depress
the power switch, located on the bottom right of the unit. (Red indicates “Power On” position)
Operator can expect a delay of a few seconds before hearing fan running. This is due to a built-in
motor “Soft-start feature”.
Position the exhaust arms to optimize the fume capture.
Follow maintenance procedures below.
5. Maintenance and Cleaning
5.1. Filter Unit - Maintenance and Safety
The Fume Extraction System is designed with low maintenance in mind. The housing is ESD
safe plastic. Here are a few tips to keep your system running in top shape:
To clean, use a light wipe with a gentle cleaner to prevent buildup of particulate and flux residue
(be sure unit is turned off while cleaning).
Do not block the exhaust outlets; this will cause the operating temperature of the system to rise, potential
damaging the unit, and drop in performance.
Do not defeat the filter interlock switch. Running the system without a filter will allow particulate and flux
residue to adhere to the blower and decrease the life of the system and increase noise.
Do not lift system while operating
Be sure to handle filters with care.
5.2. Filter Replacement Timing
Model BVX-201
When fumes are filtered inside the unit, the particulates captured will start clogging the filter over time.
The coarse particles are collected in the pre-filter while fine particles will be collected in the HEPA
filter. The clogging will result in a reduction of the airflow, which may reduce the amount of fumes
extracted from the work area. This condition may not necessarily require filter replacement. One step
is to move the optional extraction arms closer to application if possible. If the fumes are not extracted
any longer to previous satisfaction level, filter replacement is required. When the filters are blocked,
an alarm will start to sound. See section 5.4 for filter replacement procedures.
Warning!
Do not attempt to clean filters. Attempted cleaning can damage filters and cause potential risk to
health and equipment.
Notice: Metcal recommends replacement of main filters annually as a minimum. Regular changing of
the pre-filter will prolong the life of the main filter (HEPA/Carbon). Use only original replacement
filters.
Model BVX-203
This model features a deep-bed gas filter, which generally does not clog and reduce airflow as
common with HEPA filters. Replace both filters, pre-filter and carbon filter as soon as odors become
noticeable.

Notice: Replace filters at least every 6 months, as most gas-phase filter media achieve saturation by
adsorbing moisture from ambient air. Use only original replacement filters.
5.3. Safety Interlock
The safety switch is an interlock which turns off the fan when the main
filter is removed and when the fan inlet opening is exposed. The safety
switch also prevents the system from operating without filters in which
case the impurities would contaminate the internal unit.
WARNING!
Do not bypass safety interlock. Bypassing safety interlock could result in
injury to persons.
5.4. Filter Replacement Procedure:
1. Turn unit off.
2. Disconnect the power cord.
3. Unlatch the filter cover (see illustration on right).
4. Remove filter cover.
5. Replace the filters. (Pre-filter/main filter). Ensure to place main filter inside the alignment pins
so that interlock switch is depressed.
6. Replace filter cover and ensure proper fit on bottom housing. Hook both latches into filter
cover and press down carefully.
Caution!
Do not use force. If latches do not close, check proper seating of filter cover on bottom
housing.
7. Reconnect power cord and turn system on.
8. If unit does not operate, refer to troubleshooting section.
Notice: Always use new replacement filters!

5.5. Filter Disposal
The gas filter collects some organic materials and care in disposal may be required. The filter
may contain toxic materials and inhalation of dust particles or exposure to skin must be avoided.
Please consult the MSDS Sheets for the material used at your facility and follow the prescribed
handling instructions
6. Troubleshooting
Problem
Possibly Cause
Check and Correction
No air flow
No Power
Check On/Off Switch
Check power outlet
Check power cord
Check for filter
Check safety interlock switch
Little air flow
Air leak
Check hose/arm for leaks
Check hose/arm for proper installation
Check hose/arm for partial clogging
Audible alarm activating
High ambient Temperature
Please refer to calibration procedure 6.1
The BVX-200 filter-block alarm is factory calibrated to a specific temperature setting and will, for most
users, require no adjustment. However, users in warmer climates may need to adjust the BVX-200
temperature setting to prevent false alarms.
1. Assemble the BVX-200 as per the User Guide. Both the remote switch the main power switch
should be in the ‘Off’ position.
2. Switch On the main unit and press the remote switch. The remote switch LED will light when
powered. The unit will run and you will hear the alarm sound momentarily but then stop while the
motor continues to run. Allow the motor to run for at least 10 minutes to attain normal operating
temperature.
3. With one inlet port already blocked, place a block plate with a 6mm Ø hole over the other air inlet
and listen for the alarm tone. If heard, go to next step; if not, remove the plastic blanking-plug and
turn the potentiometer counterclockwise until the alarm tone is heard.
4. Replace the 6mm Ø hole blank with a 15mm Ø one. If the alarm still sounds, gently adjust the
potentiometer by turning screwdriver clockwise until the alarm can no longer be heard. Refit the
blanking plug once the correct setting is obtained.
To make your own block-plates:
A standard CD has a 15mm Ø hole at its center.
A paper hole-punch may be used on stiff card to make a hole that is approximately 6mm.
