maximum shaft output of 350 RPM with 1750 RPM
shaft input. Choice of the air-powered (variable speed)
or the electric motor.
LSA 200H - (hydraulic) direct drive, with 0 - 350 RPM
shaft output using the 0.25 HP motor.
LSA 220 - 6.32:1 ratio gear reducer, and a standard
maximum shaft output of 280 RPM with 1750 RPM
shaft input. Choice of the air-powered (variable speed)
or the electric motor.
LSA 220H - (hydraulic) direct drive, developing 0 to
280 RPM shaft output using the 0.25 HP motor.
LSA 300 - 6.32:1 ratio gear reducer, and a standard
maximum shaft output of 140 RPM with 900 RPM
shaft input. Choice of the air-powered (variable speed)
or the electric motor.
