PRODUCT OVERVIEW
Crucible control
EFFICIENCY AND RELIABILITY
The frictionless, rotary, non-reciprocating design results in lower air consumption and almost unlimited operating life.
LOW MAINTENANCE
With no sump, there is no maintenance required.
COMPACT POWER
The positive displacement rotary action combines the high power-to-weight ratio of a vane type motor with the positive starting and high torque of piston motors many times their size and weight.
VERSATILITY
The combination of high power and compact size lends Rotair Motors to applications where size and weight are important, including new mobile equipment that was previously not practical due to the power requirement. The motors are fully reversible and may be mounted at any angle and are submersible.
EXTENSIVE MODEL RANGE
Full range of power outputs from 1 to 70 hp, in mountings to match ISO and Nema electric motor mountings or piston motor equivalents. Rotair will even supply custom built units to fit your application, offering savings in size and cost. We will build systems incorporating valves, brakes, air equipment and gear units in helical, planetary, bevel or worm types, foot, flange or shaft mounted. Ratios up to 2000:1 and torque outputs up to 350,000 ft-lbs.
LEAD TIME
Our build programme is geared to today’s needs - we can generally fill your requirements on a build-from-stock basis from our extensive component inventory.
PRICE
Due to their simplicity of design and compactness, Rotair motors are naturally a more economical choice.
