Figure 2 shows an example of poor air circulation,
where the air filter is placed too close to obstruc-
tions and the velocity of the air is lost and circula-
tion is diminished.
Below is a list of things to keep in mind when
selecting a spot for the air filter:
• Study your shop layout and try to determine
the best location. Obstructed air flow will
cause a short cycle effect, producing unsat-
isfactory results. There must be a clearance
of at least 5-10' between the front and back
of the unit and any obstructions.
• Try to place the air filter near areas where
sanding will take place.
•
Try to place the unit where it is easy to
access for turning on, cleaning, and main-
taining.
The G0573 Two Speed Floor Air Filter is designed
to recirculate the entire volume of air in a 30' x 40'
x 8' room approximately 12 times in one hour.
For the best filtering effect, the volume in a room
should be recirculated at least 6-8 times every
hour.
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 air filter;
where W = Width, L = Length and H = Height of
your room, in feet. The highest rate of air move-
ment for the air filter is 2000 cubic feet per min-
ute.
W' x L' x H' = Minutes for one recirculation change
2000
Step 1: 30' x 40' x 8' = 9600 = 4.8 Minutes
2000 2000
Step 2. Calculate how many times per hour the
volume is recirculated through the 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.
Step 2: 60 = 12.5 Times per Hour
