Specially configured low pressure & high efficiency screw air compressors ready for export to France.
Across major French industrial hubs—from the chemical corridors of Lyon and Auvergne-Rhône-Alpes to the vast manufacturing zones in Grand Est and Hauts-de-France—there is a swift pivot toward decarbonization and optimal energy conservation. In industries such as wastewater treatment aeration, pneumatic bulk conveying, glass manufacturing, and cement manufacturing, the historic practice of using a standard 7-bar to 8-bar air compressor and throttling the air pressure down to 3-bar or 5-bar via pressure regulators is increasingly recognized as a massive energy waste.
When you throttle compressed air, you are literally throwing away the power consumed to compress the air to that redundant high pressure. This realization is prompting French plant engineers to seek dedicated low-pressure rotary screw air compressors (0.3 MPa to 0.5 MPa / 3 bar to 5 bar). By compressing air directly to the exact target low pressure needed, companies achieve immense energy reductions, aligning directly with French ADEME (Agency for Ecological Transition) guidelines, the "France 2030" investment plan, and the European Union's ErP directives.
A custom 0.3 MPa (3 bar) low pressure screw compressor saves approximately 30% to 50% of the electrical energy compared to a conventional 0.8 MPa compressor operated at a throttled 3 bar outlet. Reducing the unnecessary pressure margin directly translates into decreased kW/m³/min Specific Power consumption.
Get a Custom Savings AnalysisLow pressure screw compressors are not generic utilities; they are highly customized assets built to improve specific production cycles. Here are the core industries in France where our 3-bar and 5-bar systems are deployed:
In municipal and chemical wastewater treatment facilities (such as those serving Paris, Marseille, and Toulouse), large quantities of continuous air at 3 bar to 5 bar are required to oxygenate aerobic biological reaction tanks. Our Permanent Magnet (PM) VSD low pressure compressors regulate output dynamically, aligning directly with seasonal and daily sewage load variations to minimize municipal power grids stress.
France's rich tradition of wine bottle production, cosmetics packaging, and table glassware relies on stable, pulsation-free low pressure compressed air for forming, cooling, and mold actuation. Ensuring a steady supply of oil-free and low-pressure micro-oil air at 0.3-0.4 MPa protects the delicate glass structures from structural cracks and aesthetic deformation.
For transporting dry bulk ingredients like flour, sugar, starch, and grains through piping systems in industrial bakeries and processing plants, low pressure air prevents materials blockages while keeping the transfer velocities uniform. Lower pressures prevent product degradation and pipeline wear, delivering raw materials safely across the factory floors.

Contact Our Technical EngineersHow dual-stage rotary compressors and PM VSD motors combine to minimize specific power requirements for large scale manufacturing.
By splitting the compression ratio across two independent mechanical stages, we reduce inter-stage pressure rises and cooling requirements. This structural optimization lowers internal leakage losses and raises volumetric efficiency by up to 15% compared to single-stage units.
Using IE4 and IE5 high-efficiency permanent magnet synchronized motors, our low-pressure compressors retain optimal efficiency even at partial loads (down to 25% capacity). Unlike induction motors, PM motors avoid excitation losses, reducing heat load and power draws.
Our integrated VFD/VSD systems constantly monitor line pressure, adjusting rotor speed within milliseconds. This keeps pressure variance limited to ±0.01 MPa, eliminating severe pressure spikes and energy-wasting unload cycles.
