ENVIROMAC MAC1 107.1022 - Manual (Page 3)

B) CHARCOAL FILTERS
Both doors contain the charcoal filters.
They should be replaced 1 or twice a
year in a normal welding environment.
C) ELECTRICAL COMPARTMENT
The unit operates off 120 volts single
phase utilizing a 20-amp service outlet.
The motor draws about 17.5 amps under
full load conditions. There is a contactor
and an overload inside this compartment
and the overload is set at about 20%
above the 17.5 amps. This will
automatically shut off power to the motor
in the event of an overload. This gives
full protection to the motor. The unit has
a spring activated on/off dual switch on
the front of the panel. There are facilities
to put in an optional halogen light in the
hood of the arm. This requires a 120 Volt
to 12-volt step down transformer for this
option. The halogen light will run off of
12 volts AC.
C) CABINET
The cabinet is built of 14-gauge steel.
There are 2 doors on the unit and the
discharge of the clean air is through these
2 doors.
D) BLOWER AND MOTOR
SECTION
The motor is a 1.5 HP TEFC, 120/1/60,
3600 RPM. The fan is a high-pressure
fan fabricated out of 14 gauge metal.
E) ADDITIONAL EQUIPMENT
FEATURES
The standard unit comes equipped with
the Snorkvac™ 10 Ft. flexible fume arm.
The 3 articulated joint sections could be
adjusted to suit the operator as to the ease
of movement of the 4 different
articulations. There is an optional 14 Ft.
Snorkvac™ flexible fume arm.
MAINTENANCE SCHEDULE
Filter maintenance
The filters should be replaced when there
is inadequate suction at the hood. The
prefilter should be replaced whenever the
suction deteriorates. The HEPA filter
only has to be replaced when the suction
is still low after replacing the prefilter.
The HEPA filter does not have to be
replaced every time the prefilter is
replaced. You normally will replace 3 or
4 prefilters to every HEPA filter.
Part Numbers
Prefilter (Disposable): 107.1016
HEPA filter: 107.1015
The charcoal door filters should be
replaced once or twice a year. The arm
has friction discs with washers, which
can be adjusted to suit the operator. The
unique design of the arm minimizes any
problems related to sagging, burn holes
in the hose and ease of arm movement.
This is a major problem with
conventional less expensive fume
extractor arms.
Thank you for purchasing your new
ENVIROMAC
Portable Welding
Smoke Extractor/Portable Dust
Extractor.
The air in your work area will be much
healthier to breathe. The HEPA filter
should be used to filter out Hexavalent
Chromium Fumes when welding
stainless.
