Site planning is an important step to maximize the
effectiveness of the hanging air filter. Air circulation
must be thought out and all obstructions to the air path
considered.
Think of air circulation in terms of the circular motion of
the air before and after the air filter. The air exiting the
filter is exhausted at a higher velocity than that entering
it. Consequently, exhaust being vented inside a building
can have an effect on the pattern of air circulation.
Air circulation patterns will vary depending upon which
air flow speed is used and according to your specific shop
setup. =`^li\7 shows an example of good air circulation.
=`^li\8 shows an example of poor air circulation, where
the air filter is placed too close to obstructions. In this
situation, the velocity of the air is lost and circulation is
diminished.

• Study your shop layout and try to determine the best
location for the hanging air filter. Air flow that is
obstructed will cause a short cycle effect, producing
unsatisfactory results. There must be a clearance of
at least 3 ft. from any obstructions in front and back
of the unit.
• Try to place the air filter in front of high dust
producers like sanders or near areas where sanding
will take place.
• Do not place the hanging air filter where garage
doors may pass closely or where it may impede
transport or movement of any other object.
• Try to place the unit where it is easy to access for
turning it on, cleaning and maintenance.

• Where the mounting brackets attach is the top of
the unit. The hanging air filter can only be secured
by the machine hooks on its top.

Figure /. The air filter placement is too
close to the walls and leaves much of the
room unfiltered.
• Make sure that an electrical outlet
with a properly grounded receptacle is
available at the location you choose.
• The hanging air filter must be
supported by wood joists that are
capable of supporting at least 100 lbs
each. DO NOT attach the hanging air
filter to only sheet rock, press board
or paneling. These materials cannot
support the filter, and it may fall.
• Avoid hitting your head on the hanging
air filter. Make sure there is enough
clearance between the unit and the
ground, especially important in a
basement. If possible, position the air
filter in an area that has little foot
traffic but still offers easy access to
the switch and filters.
