Thrust Fan and Air Cushion Pressure Fan Information

Note1: The following fans are just a few of the possible combinations that are available from us, with stated diameters, type and estimated performance outputs. We can also build a custom fan configuration for your application. Provide us with the details requested on our QUOTE REQUEST FORM and we will find the best fan or propeller combination for your application. If your duct is already constructed, we can cut the fan diameter to fit with the proper blade-tip clearances for maximum efficiency. For more information click HERE and send us an e-mail.

Note2: For our estimated fan performance calculations, we use 4 in. wg. (supports 20.8 lbs. per sq.ft. of air cushion area) as our default pressure for the air cushion, unless otherwise stated, and 1 in. wg. for thrust fans, all using a AMCA style "A" duct style, 0.5% of fan diameter for blade tip/duct wall clearance for pressure fans and 1% for thrust fans. A Taper-lock bushing is included to mount the fan to your keyed engine PTO or drive shaft. Flange-style mounting is also available upon request. Just tell us what you want. Expect about 10% less performance if a proper duct is not used or if there is excessive blade tip clearance to the duct wall.

Note3: We suggest you use our Hovercraft Lift Calculator and 1/2" hover height to determine the airflow in CFM for your hovercraft air cushion application, based on its weight, and the length and width of the air cushion area. Ignore the other outputs for our fan matching purposes. Find the "CFS" output then multiply times 60 to convert to CFM. Then find a fan below that closely matches the CFM needed or HP you have available. It is suggested to have at least 15% to 20% more HP than your calculations show is minimally required, to account for hot days, high-density altitude, and so your engine can operate at less than Wide Open throttle settings. Always have more power and airflow than you need, instead of needing more power and airflow than you have.
