Wastewater treatment is a critical environmental protection discipline dedicated to transforming polluted industrial and municipal effluent into clean water suitable for reuse or safe discharge. In this process, biogas compressors play an essential role by pressurizing raw digester gas - enabling its purification into biomethane for use in onsite generators and heating equipment, thereby supporting circular energy use and reducing fossil fuel consumption. Oil-free screw blowers, on the other hand, are central to aeration systems within biological treatment stages; they inject precisely controlled air volumes into aeration basins, fostering microbial oxidation of organic pollutants. The reliability and efficiency of these blowers directly determine oxygen transfer rates and, consequently, the overall removal efficiency of contaminants such as BOD and COD. As regulatory and sustainability requirements tighten worldwide, the integration of high-performance biogas compression and oil-free aeration technologies is driving new levels of process optimization and environmental compliance.

• Power Range: 4–450 kW, covering small lift stations to large municipal plants.
• Flow Capacity: 1.8–190.3 m³/min, adaptable to varying oxygen-demand profiles.
• Operating Pressure: 40–150 kPa (up to 200 kPa max), ensuring sufficient back-pressure tolerance in diffuser grids.
• 100% Oil-Free Compression: Dry twin-screw airend eliminates any risk of oil carryover, preserving water quality and avoiding secondary contamination.
• Aerospace-Grade Coatings: Ultra-tight clearances and supercoatings reduce internal leakage, boosting efficiency and service life.
• Energy Savings Up to 30%: Optimized rotor profiles minimize pressure losses compared to traditional Roots blowers, delivering significant operational cost reductions.
• Direct-Drive Design: Eliminates belts and pulleys, reducing maintenance intervals and spare-parts inventory.
• Precision Gearbox Coupling: Ensures synchronous rotor-motor speeds for low vibration and high reliability.
