Installation Guide

Try not to run your fi lter for long periods
at or above 70% humidity, the water mol-
ecules in the air start to get stuck in the
carbon pore structure and slowly diminish
the life of the fi lter.
Can I push or pull through the fi lter?
You can both pull through the fi lter or push
air through the fi lter. If you are going to push
air through the fi lter it is recommended to
take off the outer pre-fi lter and place the pre
fi lter prior to the air entering the carbon bed.
How do I size the proper fan and fi lter
to my room?
All Can-Filters
®
come with a maximum
exhaust and maximum recirculation rating,
as long as you do not exceed the maximum
exhaust rating when matching your fan to
your fi lter you can be confi dent that the air
passing through your fi lter will exhaust out
as clean air.
Calculate the cubic feet of the room
(Length x Width x Height) and divide that
number by the number of minutes you
would like to exchange the air in the room
(1 – 3 minutes is recommended) that gives
you the recommended minimum CFM that
you need to exchange the air in that room.
(Length x Width x Height) ÷ 3 = Minimum CFM
Eg) 10ft x 10ft x 20ft = 2000 Cubic Feet
2000 Cu.ft ÷ 3 = 667CFM
A 667 CFM fi lter is minimum fi lter size for
this size area. Match fan to fi lter.
Consult performance charts to determine
which fan will meet the needs of your
application.
How much CFM loss is there through the
fi lter?
Every different size of fi lter provides a
different resistance to each different size
and style of fan you put on it, a fi lter at
the maximum exhaust CFM rating has
approximately 0.7 wg. pressure drop.
All fans will have a lower CFM at a higher
pressure. Can-Fans
®
and Max-Fans™ are
highly effi cient and lose the least amount
of CFM when put under a resistance.
Can-Fans
®
will only lose 15%–20% of their
air fl ow through a fi lter. Max-Fans™ only
lose 7%–14% of their CFM All other fans
lose up to 60% of their CFM.
For example at .5" wg: The 10" Max-Fan™
goes from 1019 CFM to 885 CFM.
The 12" Max-Fan™ would go from 1708
CFM to 1595 CFM."
How much CFM is lost through a 25 ft.
section of ducting?
Approximately 3% (straight hard cast) to
7% (fl ex ducting). 1% – 4% additional loss
for every 90˚ bend.
