OEM Oil-Free Screw Blower Manufacturer & Exporter Serving Paris & Île-de-France

Traditional Roots blowers operate on an external compression principle where uncompressed air within the rotor chambers is forced against discharge line pressure suddenly. This process causes large pressure pulsations, high discharge heat (often over 120°C), and substantial thermodynamic inefficiency. In contrast, our oil-free screw blowers utilize precision helical male and female rotors designed with internal volume reduction. The air is gradually and smoothly compressed inside the flute pockets before reaching the exhaust port. This internal compression reduces thermodynamic losses by 25% to 35%, lowers discharge air temperature significantly, and cuts plant acoustic noise from ~90 dBA down to <72 dBA—a vital metric for facilities situated near Paris metropolitan residential perimeters.

Class 0 is the most stringent air purity standard, certifying zero residual hydrocarbons (oil aerosol, liquid, or vapor) down to levels below 0.003 mg/m³. Honest Compressor achieves this without reliance on filtration traps by physically separating the compression chamber from bearing lubrication. We utilize carbon-face non-contacting labyrinth seals backed by atmospheric vent gaps. Even under catastrophic bearing seal leakage, oil cannot cross the atmospheric barrier into the dry compression chamber. Each unit is tested and supplied with certified third-party emissions analysis for validation by French food (DGCCRF) and health agencies (ANSM).

All units engineered for export to France are manufactured natively for 400V ±10%, 3-phase, 50Hz electrical distribution. VSD frequency convertors incorporate built-in line reactors and RFI/EMC input filters conforming to EN 61800-3 category C2. On the controls side, our standardized PLC touch controllers feature native French language localization and support industry-standard industrial communication protocols: Modbus-RTU/TCP, Profinet, and Ethernet/IP, facilitating plug-and-play integration into regional SCADA systems such as Wonderware, Siemens TIA Portal, or Schneider EcoStruxure.

Because our rotors never contact each other—synchronized via precision ground helical timing gears—there is zero mechanical friction or surface wear within the compression cavity. Routine preventative maintenance is limited to air intake filter cartridge replacement (every 2,000 to 4,000 operating hours) and bearing synthetic lubricating oil renewal (every 8,000 hours or annually). Precision angular contact bearings have a rated L10h bearing life exceeding 40,000 to 60,000 operating hours. Electricity constitutes 82% of a blower's 10-year Life Cycle Cost (LCC); the 30% reduction in power consumption pays for the entire initial equipment purchase price in under two years of continuous operation.

We partner with regional industrial service contractors and maintain an emergency inventory of consumable service packs (seals, bearings, sensors, gaskets, intake media) with next-day courier delivery throughout mainland France. For turn-key projects, our Shanghai application engineering department works directly with your local mechanical installers via remote diagnostic telemetry and comprehensive FAT commissioning video sign-offs. Our digital controllers feature remote IoT monitoring gateways allowing our factory engineers to review operational telemetry, vibration frequency trends, and discharge temperatures in real time.
