Model G9956 (Mfg. Since 8/15)
The Model G9956 will recirculate the volume of
air in a 20' x 20' x 8' room approximately 26 times
in one hour.
We recommend that the volume of air in your
room be recirculated at least 6-8 times every
hour. Therefore, rooms with a larger volume will
require two or more air filters to achieve proper
filtering.
To calculate the recirculating rate for your
shop space:
Filtering
Performance
Step 1: Use the formula below to calculate how
long it takes to circulate all the volume of air in a
room with the double air filter; where W = Width, L
= Length and H = Height of your room, in feet. The
maximum rate of air movement for the air filter is
1400 CFM.
W' x L' x H'
= Minutes for circulating 1 time
CFM
Example: 20' x 20' x 8'
=
3200
= 2.29 Minutes
1400 1400
Step 2: Calculate how many times per hour the
volume is recirculated through the double air filter
by dividing 60 minutes by the circulating time from
Step 1. The result is listed as times per hour.
Example: 60
= 26.2 Times per Hour
2.29
When the air filter is not in use, unplug the power
cord from the power source. Place the cord away
from potential damage sources, such as high
traffic areas, sharp objects, heat sources, harsh
chemicals, water, damp areas, etc.
