‌Optimized Rotor Configuration:‌ Utilizing the standard Atlas Copco SAP profile, the rotor employs a 4/6 tooth configuration with equal rotor diameters. This design, compared to alternative 5/6 (Sigma) or 4/5 (Cyclon) tooth arrangements, significantly enhances the rigidity of the female rotor. The increased rigidity reduces deformation under load and minimizes internal leakage losses, contributing to higher volumetric efficiency.

‌Advanced SAP Profile & Port Design:‌ The SAP profile is engineered so that under compression force, contact is established at the trailing edge of the tooth flank. This creates a tight sealing line between rotors. Coupled with a minimized exhaust port (which reduces the “leakage triangle”), this design drastically cuts internal leakage and associated energy loss. These improvements enable a higher internal pressure ratio (up to 10 bar) and enhance overall efficiency, particularly in 10 and 13 bar models that benefit from larger rotor diameters.

‌Enhanced Dual-Seal System:‌ The oil and gas seals are designed with a minimal non-contact gap, offering superior sealing efficiency, reliability, and service life compared to traditional labyrinth or mechanical seals. A critical design element is the small leakage port (E) located between the two seals. This port serves as a backup pathway, ensuring the continuous delivery of compressed air even in the unlikely event of a primary seal failure, thereby safeguarding system uptime.

‌Efficient Gearbox Design:‌ The integrated gearbox contributes to reduced energy consumption and lower operating costs. The axial force generated by the gears effectively counterbalances the axial force acting on the male rotor. This improves overall mechanical balance and operational efficiency—an advantage not achievable in direct-drive configurations.

‌Optimized Thermal Management:‌ The system is designed to maintain the lowest possible operating temperature, which is critical for preserving oil integrity, component longevity, and overall efficiency.
