Our new Vengeance Expander running on compressed air at 90 psig, 30 CFM. This model features a 6 inch diameter rotor and only 3 moving parts. It can be scaled up or down to any size or stacked in tandem for controlled modular power. We can deliver full useable direct-drive torque at the output shaft without a speed reducer gearbox.
The Expander is shown here powering the drivetrain of a 1972 Corvette chassis. The sound you hear when the engine stops is a one-way ratcheting sprag we added for neutral and coasting.
