is diminished. The following is a list of things to
keep in mind when determining the placement of
the air filter:
Site Planning
Site planning is an important step to maximize the
effectiveness of the double air filter. Air circulation
must be thought out and all obstructions in the air
path considered.
•
Study your shop layout to determine the best
location for the double air filter. Air flow that is
obstructed will cause a short cycle effect pro-
ducing unsatisfactory results. There must be
a clearance of at least 12" from any obstruc-
tions in front and back of the unit.
The G9956 Double Air Filter is supplied with a
pair of directional vents which allows the user to
direct the flow of circulation. However, while the

they will have a limited effect when the double
air filter is placed incorrectly in the room as in
Figure 4. When placed too close to obstruc-
tions, the velocity of the air is lost and circulation
Do not place the double air filter in the path of
garage doors or where it may impede trans-
port or movement of any other object.
Place the unit in a location that provides easy
access to turn on, clean and maintain.

Figure 4. Poor circulation. Placed too close to
the wall, the air circulation short cycles leaving
much of the room unfiltered.

Filter Capacity
•
•
The double air filter must be supported by
joists when hanging. These joists should be
capable of supporting at least 150 lbs. DO
NOT attach the double air filter to sheet rock,
press board or paneling. These cannot sup-
port the filter and it may fall.
The G9956 Heavy-Duty Double Air Filter is
designed to recirculate the entire volume of air
in a 20' x 20' x 8' room approximately 26 times
in one hour. For the best filtering effect, the vol-
ume in a room should be recirculated at least 6-8
times every hour.
To avoid hitting your head on the double air
filter, make sure there is enough clearance
between the unit and the ground (at least
seven feet). This is especially important in a
basement. If possible, position the air filter in
an area that has little or no foot traffic but still
offers easy access to the switch and filters.
To calculate the recirculating rate for a given
volume:
Step 1. Calculate, how long it takes to circulate all
the volume of air in a room with the double air fil-
ter; where W = Width, L = Length and H = Height
of your room, in feet. The rate of air movement for
the air filter is 1400 cubic feet per minute.
W' x L' x H'
Eye Bolts
= Minutes for circulating 1 time
1400
Step 2. Calculate how many times per hour the
volume is recirculated through the double air filter
by dividing 60 minutes by the amount of time it
takes to circulate the volume once. The result is
listed as times per hour.

for the connecting links and eyebolts on the
double air filter.
The double air filter may
fall and cause serious
injury if it is not properly
mounted. DO NOT fasten it
to sheet rock, press board,
paneling or anything other
than joists.
5. Cut the chain to equal lengths and attach a
connecting link to each end.
6. Secure a length of chain to each mounting
eye.
Follow these steps and refer to Figure 5 when
hanging the double air filter.
7. GET SOME HELP! With at least one other
person supporting the weight of the double
air filter, connect the chains to the lag eye
bolts.
NOTE—DO NOT use hooks in place of lag eye
bolts. If the double air filter is bumped it could
fall.
