Single-phase 230 V lubricated screw compressor, from 3.7 to 9 kW: the continuous flow and quiet running of a screw, with no three-phase supply on site.
21 models in the catalogue, flow 0.3 - 1.2 m³/min, pressure 8 - 13 bar, noise level 55 - 60 dB(A).
How it works ↓
What is a single-phase screw compressor?
A small lubricated screw that plugs into a 230 V socket, with no three-phase supply on site. It keeps the qualities of the screw, continuous flow and a moderate noise level, where a piston compressor would be noisy and intermittent.

The single-phase screw plugs into a 230 V socket: from 3.7 to 9 kW, it is the machine of the workshop, the garage, the laboratory that has no three-phase supply. It keeps the qualities of the screw, continuous flow and quietness, where a piston would be noisy and intermittent.
Beyond 9 kW, three-phase becomes necessary and the fixed-speed range takes over.
A lubricated screw compressor in a format designed for a 230 V single-phase supply, with no three-phase needed on site. The two helical rotors compress the air continuously, lubricated and cooled by oil injection, as on a standard screw compressor.
The point: to bring the regularity, low noise and longevity of screw technology where only single-phase is available (small workshops, garages, craft trades), which until now had to make do with a noisy piston compressor with a limited service life.
Small workshops and craftspeople without a three-phase connection: car repair, joinery, bodywork, finishing workshops. The way to move from piston to screw without modifying the electrical installation.
230 V single-phase connection
Runs on a standard single-phase socket: no three-phase upgrade needed. Immediate installation where the piston compressor used to be the default.
The comfort of screw technology
Air delivered continuously, without pulsation, with a noise level far below that of a piston compressor of comparable flow.
Longer life than a piston
The air-end has no parts in reciprocating friction: service life and maintenance intervals well beyond those of a piston, for daily workshop use.
Compact and all-in-one
Workshop format, often mounted on an air receiver, ready to use. Small footprint, quick commissioning.

How to size an air compressor: flow, pressure and storage
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.
