9-Blade Multiwing Fan Hub, 6-Bolt 2.45" BCD, 1" Bore

Multiwing 9-blade Z-series fan hub, die-cast aluminum, ready to bolt on: 1" bore and six 3/8" bolts on a 2.45" circle. This is the standard pattern on Amphibious Marine and Sevtec hovercraft lift fans.

• 9 blade positions, Z-series
• 1" bore
• 6 bolts (3/8") on 2.45" bolt circle

Which blades fit

Takes Multiwing and Wing Fan Z-series blades, such as the 4Z, 5Z and 7Z, and the Wing Fan P4Z, P5Z and P6Z. Blades of the two brands fit the same hub, but they may not weigh the same, so use one brand per fan (or place them in opposite positions to keep the fan in balance).

Building a fan

Add 9 fan blades and our Z-series cutting service, or buy the complete 24" 4ZL 9-blade fan. The same hub with a 1.125" bore is here.
