ABOUT THE PRODUCT
PRINCIPLE OF OPERATION
The ENVIROMACPortable Air Cleaner is a
media type Air Cleaner operating on a two-stage
filtration principle. After the contaminant is
picked up at the hood of the MovexFlexible
Arm it is then drawn through the arm and
through the fan assembly and discharged to the
inside part of the high efficient washable filter.
The filtered air is discharged out the 2 doors. The
2 doors contain charcoal, which eliminates most
gases that might be in the filtered air stream. The
high efficient washable filter collects particulate
only and does not filter gases, which is the sole
purpose of the charcoal door filters.
MAJOR COMPONENTS
The ENVIROMACPortable Air Cleaner is a
self-contained unit comprised of a flexible arm
(for source capture), fan and motor assembly,
high efficient washable filter, (2) carbon door
filters, complete cabinet housing and an
electrical compartment which also included a
Contactor overload.
A) HIGH EFFICIENCY HIGH EFFICIENT
WASHABLE FILTER
This filter is a high efficiency high efficient
washable filter. The suction will deteriorate at
the hood as the filter loads up with particulate.
Eventually the filter will have to be cleaned. To
commence cleaning the filter, you must remove
the doors closest to the front of the machine
which is where the switch and nameplate are
located. This door is removed by removing the
(2) plastic knobs near the bottom of the door and
then pulling the door out on an angle so the door
is free from the (2) welded bolts. Then pull down
on the door to let it slide down from the top of
the door. You then remove the filter by lowering
the scissor jack with a ratchet. Then slide out the
cartridge filter. You then invert the filter upside
down and utilize the existing gasket on the filter
to make a seal and take an air hose with about 80
P.S.I. and blow the filter from the outside to
remove all of the filter particulate that is on the
inside of the filter. You can now put the cleaned
filter back into the machine and tighten the filter
by raising the scissor jack. Make sure the filter is
resting on the back of the filter cradle butted up
against the tab locators. Make sure that the top of
the filter fits inside the top plate that has a 1” lip
on it. Make sure the scissor jack is high enough
to allow an airtight seal on the top of the filter
gasket. Caution should be taken not to apply too
much pressure to the filter or you could squash
the filter if too much pressure is applied. Always
blow the outside of the filter with the gasket of
the filter either on the floor or a container to give
you a good seal so that the dirt does not escape
under the seal. Never blow from the inside as the
contaminant will blow all over the surrounding
area and will also force the very fine particulate
into the media.
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 13.5 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 13.5 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 24

Volt step down transformer for this option. The
halogen light will run off of 24 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 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 a 14 Ft.
Snorkvacflexible arm. The 3 articulated joint
sections could be adjusted to suit the operator as
to the ease of movement of the 4 different
articulations.
MAINTENANCE SCHEDULE
The filter should be cleaned or replaced when
there is inadequate suction at the hood. The
charcoal door filters should be replaced once or
twice a year. The Movex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 arms.
Thank you for purchasing your new
ENVIROMACPortable Air Cleaner. The air
in your work area will be much healthier to
