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. Dimensions: (with pre-filter) Outside Diameter: 42cm / 16.5" Height: 75cm / 29.5" Total Weight: 36kg / 79lbs. Carbon Weight: 28kg / 61.6lbs. Carbon Bed Depth: 6.5cm / 2.56" 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 i
