How it works ↓
What is a permanent magnet rotary vane compressor?
Vanes, a permanent magnet motor and a drive: the most efficient version of the family. The magnet motor keeps its efficiency at low speed, where a conventional motor loses it, and pressure stays stable within ± 0.1 bar.

Rotary vane, permanent-magnet motor and drive: the most efficient version of the family, from 7.5 to 45 kW, for a demand that varies strongly through the day. The permanent-magnet motor keeps its efficiency at low speed, where a conventional motor loses it.
On a flat load, this sophistication brings nothing: the base range is enough.
Here the vane air-end (off-centre rotor and sliding vanes) is driven by a permanent magnet motor controlled by a variable frequency drive (PM-VSD). Speed adapts continuously to air demand.
This combines the strengths of rotary vanes (quietness, intermittent duty accepted) with those of the drive (energy savings under variable load, stable pressure, soft start).
Quiet sites with fluctuating demand: the winning combination when you want both the acoustic comfort of rotary vanes and the savings of variable flow. Print shops, laboratories, multi-station workshops with irregular loads.
Savings under variable load
The drive adapts the speed to actual demand: marked energy savings as soon as consumption fluctuates, with no off-load cycles.
Permanent magnet motor
High efficiency maintained even at low speed, IP55 class F, direct coupling to the vane air-end.
Rotary vane quietness
The low noise level of rotary vane technology, reduced further at low speed thanks to the drive.
Soft start
The drive ramps up speed smoothly, with no current peak on the electrical supply and no shock to the vane air-end.

Permanent magnet VSD: what the drive really saves
What a permanent magnet drive changes on a varying load: idle hours removed, and the annual gain to be worked out from your own load profile, across 6 typical power ratings.
Two-stage screw compressor: around 10% less energy than a standard screw
A two-stage screw compressor compresses air in two steps with intercooling in between, close to the theoretical isothermal cycle. Around 10% less energy than a standard screw at constant load; with a permanent magnet drive, on a variable load, the two gains combine.
