AF24 series
AF 24 is winged profile made of extruded aluminium alloy with a 240mm chord: it is mounted and pitched over steel shafts of various diameters through custom bolted blocks, so that impeller is firm and performing, with a number of blades that can fulfill the most challenging requirements. Pitching is variable when stationary and impeller fits straight on the engine shaft. All the AF 24 impellers are 60% reversible: through custom setup it is possible to have fully reversible AF 24 impellers.
