    Can-Fan Max-Fan 8" 667 CFM

    Can-Fan brings its innovation to market and sets a new standard for performance. The Max-Fan is more powerful and efficient fan that takes less energy to run. 6" - 14" come pre-wired with an 8’ - 120 volt power cord. 16"-20" come with an 8' whip (240 Volt). 5 year warranty.

    The Can Fan Max Fan 8" inline duct fan saves energy through energy efficient design, which lowers lifetime cost of energy by 70 to 90%. The Max Fan 8 inch is quiet and highly aerodynamic. The Max Fan's optimized mixed flow is quieter than other fans of the same size.

    Max-Fan FAQ:

    Do Max-Fans use brushless motors?

    Yes. The Can-Fans and Max-Fans use a brushless motor in their operation.

    Are your fans Speed Controllable?

    Yes. Both the Can-Fan and the Max-Fan line of fans are speed controllable, DO NOT SET THE SPEED OR MOTOR CONTROL BELOW 40% OPERATING SPEED TO AVOID OVERHEATING THE FAN. The Max-Fan 12" is not conventionally speed controlled, The Max-Fan 12" requires the Can-Trol Speed control. This control provides absolutely no motor hum when controlling the fan, it also gives you the option to control the voltage entering your fan, with an easy to use dial you can go from 1v to 130V with a turn of your hand, no matter what voltage you run, your fan will not hum!

  • How To Size Fan to Filter
    To match a Can Filter for your size growing environment, use this formula: Length x Width x Height divided by 3. This figure will give you the minimum recommended CFM for your fan. Then match your inline fan to the size filter you need by getting one that's within the range that the Can Filter can operate within.

    Example, 10 x 10 x 20 = 2000 Cu. Ft.
    2000 Cu. Ft./3 = 667 CFM

    667 CFM fan is the minimum fan size for this area. After establishing fan size, match it to appropriate sized filter, IE, Can 100.

    How Much CFM Loss Through A Carbon Filter?
    Every different size of filter provides a different resistance to each different size and style of fan 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.

    How much CFM is lost through a 25ft. Section of ducting?
    Approximately 3%(straight hard cast) to 7%(flex ducting). 1% to 4% Additional loss for every 90° bend.

    Do I need to replace the pre-filter?
    It is a good idea to replace the pre-filter when they become dirty because the pre filter is blocking larger dirt and dust particles from getting into the pore structure of the carbon, a dirty pre filter increases the pressure, which will decrease the 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 at all, the reason for this is that Can-Filters uses an industrial shaker with timed intervals and a dust extraction system, to ensure a packed carbon bed. This 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 and crowds in. So if you tried packing the filter yourself, as soon as you got it as full as you think you could get it, attached a fan and turned it on, the fan would vibrate the carbon, and over time the carbon would settle and you would be left with air gaps all over the place presenting the air with channels to flow through the filter and possibly leave untreated.
