Fu Pro Air FR-335 Two-Stage Dry Oil-Free Screw Compressor | 335kW (455CV), 58.2 m³/min ISO 8573-1 Class 0 Pure Air, 7–13 Bar Adjustable Pressure, 380V 3-Phase 50Hz
Fixed-speed FR-335A & Energy-saving PM VSD FR-335APF Dual Versions
Large-flow zero-oil air source exclusive for large food factories, pharmaceutical bases & precision semiconductor workshops


Fu Pro Air FR-335 is a heavy-duty large two-stage dry oil-free screw compressor with rated power 335kW / 455CV, offered in two configurations: fixed-speed FR-335A and permanent magnet variable frequency FR-335APF. It delivers a maximum rated airflow of 58.2 m³/min with adjustable working pressure from 7 to 13 bar. The whole dry compression process requires no lubricating oil, continuously supplying Class 1 zero-oil compressed air that fully meets ISO 8573-1 standards, completely erasing risks of oil mist, oil vapor and liquid oil contamination. All gas-contact parts adopt stainless steel rotors and high-temperature anti-corrosion coating, perfectly matching large-scale food beverage production lines, pharmaceutical sterile workshops, optical precision testing equipment and semiconductor chip assembly plants. No oil residue will taint food raw materials, corrode precision lenses or damage high-precision electronic components.
Optimized two-stage rotor profile paired with interstage cooling balances compression ratio, minimizes internal air leakage and boosts volumetric efficiency significantly. The PM VSD FR-335APF intelligently adjusts airflow output based on real-time production air consumption, reducing idle power waste by up to 30% for outstanding energy-saving performance. Equipped with full intelligent central monitoring system, remote fault alarm function, super-large silent sound insulation cabinet and independent dual large-flow cooling system, supporting stable 24/7 uninterrupted heavy-load operation. No waste oil generation, low long-term maintenance cost, fully compliant with GMP food safety and ultra-clean industrial production standards for large industrial parks.
