F.A.Q.’S
F.A.Q.’s
How do I install a Flange?
To install the flange to the filter – take
the flange and gasket tape with screws
included out of the package, fasten the
foam gasket tape to the underside of
the flange by removing the sticky tape.
The tape will fit right around the
circumference of the bottom of the
flange closer to the inside edge. Once
the gasket tape is installed, center the
flange on the top of the filter, use the 6
tek screws to fasten the flange to top of
the filter. Be sure not to torque the screws
too much as air will pass through the gaps.
You can purchase a flange separate from
your filter and fan or have it come with
everything in a Box Combo.
How much CFM is lost through
the filter?
Each different size filter has a different
resistance depending on the size and style
of the fan that you put on it. A filter at the
maximum exhaust CFM rating has
approximately 0.7" wg. pressure drop.
All fans, will have a lower CFM at a
higher pressure.
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.
• Typical (Can-Fan) centrifugal fans lose
approximately 20% of their air flow
through a filter.
• Some less costly fans lose 40% – 60% of
their air flow through a filter.
• Mixed flow inline fans (Max-Fan) lose
7–15% of their air flow through a filter.
Do I need to replace
the pre-filter?
It is a good idea to replace the pre-filter
when they become dirty. A dirty pre-filter
increases the pressure drop, which will
decrease the air flow through the filter.
Can my filter be refilled?
Technically the filter can be re-filled, but it
is not a good idea to self-fill the filters.
The reason for this, is that, Can-Filters has
the equipment and facilities to provide a
true packed bed filter. This is not possible
at home. The packed bed eliminates the
possibility of preferred air channels
through the filter, because as we all know,
air does not wait in line to go through a
filter, it finds the path of least resistance.
What is the Maximum
Temperature / Humidity
I can run my filter at?
The maximum recommended temperature
that you can run your filter at is 80 Degrees
Centigrade, and as soon as you start rising
above 70% humidity, the water molecules
in the air start to get stuck in the carbon
pore structure and slowly diminish the
life of the filter.
How long does the filter last?
The life of a filter is determined by the
concentration of the contaminant, the
relative humidity and the volume of air
being cleaned. Unfortunately, there is no
indicator light on the filter that tells you
when it is ready to be replaced. Typically
12 – 18 months is expected of the Original
Can-Filter.
Can-Filters Packed Bed Design assures long life,
no maintenance, and consistent performance.
