How to Set Up a Can-Fan / Can-Filter Combo
CAN-FAN / CAN-FILTER COMBO SETUP
SUGGESTIONS:
You can set CAN-FAN / CAN-FILTER
combos up in several different ways.
You can push or pull air through the
filter, but the outer poly wrap is intended as a pre-filter to remove
dust before it gets to the carbon, so it's better to draw air up through
the filter. The carbon inside will last longer with a clean pre-filter.
The pre-filters are pretty cheap to replace, but you can hand wash them
too as needed.
MOUNTING FAN AND FILTER:
We don't recommend mounting the fan
directly onto the filter, as the vibration of the fan can cause
settling of carbon in the filter. This settling may allow air
pockets in the carbon to develop at the top, and untreated air to
pass through the filter.
You can hang the fan from a couple of
rubber bungee cords to absorb any vibration and cut down on fan
noise. Then connect the fan to the filter with standard clothes
dryer ducting (from a hardware store) securing them together with
either duct tape or screw-clamps.
The filter can then be placed in a dry
location either sitting on the floor, or hanging from a ceiling.
The length of ducting between the fan and filter doesn't matter as
long as the ducting is a clean, unrestricted shot between the two.
Straight PVC pipe can also be used for
longer distances if necessary. For maximum effectiveness, the
closer the filter is to the fan, the better, and we'd recommend
keeping them within a few feet of each other. You can get some
distance between them if you have to but it cuts down on the air
speed.
AIR FLOW OPTIONS:
There are two really good ways to use
the CAN combos.
The first is as a 'polishing'
filter where you put the connected fan and the filter into the
same area together. By drawing air through the filter repeatedly in
a closed area, it will effectively keep the air in that area free of
odors. This is how they use CAN filters in airplanes, and in
other closed environments.
The second way to use the CAN combo is as a pre-exhaust air
cleaner to remove odors from the air as you exhaust air from
your garden area to another room. You'll need a hole in a wall
somewhere for this setup in order to exhaust the cleaned air out.
All of the air that passes out of the room through the filter will
be clean air. This setup is effective enough to use the heat from
your growroom to help heat your home and not have to worry about
organic fertilizer odor issues in the house. They use CAN filters
this way in hospitals, auto body shops, chemical plants, and many
other commercial applications.
GENERAL INFO:
All CAN-FILTERS last from 1 to
1-1/2 years - occasionally longer.
The higher your humidity, and the
dustier the environment, the shorter the life of the filter.
To prolong the life of your equipment,
clean the poly pre-filter regularly, and every once in a while shake
or roll the filter around to expose new carbon within the filter.
Your CAN-FAN will last for many
years. We've been selling these fans for about 6 years now, and have
never had a warranty issue yet.
If you find that you need any
additional fertilizer odor control try
ONA PRO Gel. It's a good
compliment to the CAN Combo if needed.
