Dual-motor rotary vane
Rotary vane compressor with two motors and two air-ends, from 60 to 110 kW: each motor can run on its own, so the air does not stop on a fault.
4 models in the catalogue, flow 11 - 21 m³/min, pressure 8 - 13 bar, noise level 84 - 86 dB(A).

What is a dual-motor rotary vane compressor?
Two motors and two vane air-ends in one frame: the top of the rotary vane family, from 60 to 110 kW. Each motor can run on its own, which keeps air flowing if one side fails, without stopping production.

Flows, pressures, noise levels and dimensions recorded model by model on the catalogue sheets. Flows given at 8 bar.
Two motors and two vane airends in one frame, from 60 to 110 kW: the top of the rotary vane family, where a single rotor is no longer enough. Each motor can run alone, which gives a degraded mode without stopping production.
Beyond 110 kW, or for a single airend, the lubricated screw takes over.
This configuration carries two vane air-ends driven by two motors in the same frame. The two units can run together for maximum flow, or in alternation / cascade to adapt to demand.
Running a single unit at partial load, then starting the second when needed, makes it possible to match consumption while spreading the wear, and to provide redundancy: if one motor stops, the other keeps part of the production going.
Sites looking for flexibility and continuity of service: production where a total stoppage is unacceptable, demand spread over a wide range, a need for built-in redundancy without installing two separate machines.
Step modulation
One or two units depending on demand: flow adjusts in steps, avoiding running the full power at partial load.
Built-in redundancy
Two independent motors: if one stops, the other keeps production going. Continuity of service ensured.
Wear spread evenly
Alternating the two units balances the running hours and extends overall service life.
Rotary vane longevity
Two low-speed vane air-ends that accept frequent stops and restarts.

Sizing a compressor properly is not a matter of picking a power rating in kW: it means calculating the real flow, the right pressure and suitable storage. A 4-step method, with a worked example.
