II. Model-Specific Data (F-66SG / F-66Q)
The F-66 series is primarily designed for high-capacity applications, utilizing larger shell diameters than the F-52/F-62 series and often incorporating a more advanced separation mechanism.
| Model Series | Inlet/Outlet Sizes (ODS) | Shell Diameter (ØD) (mm) | Initial Oil Charge (Liters) | Oil Storage Volume (Liters) | Key Difference |
| F-66SG (Spiral) | 1-1/8″ to 2-1/8″ (e.g., F-6609SG to F-6617SG) | approx 140 to 165 | approx 1.0 to 1.2 | Low/None (Conventional Return) | High-efficiency separation via centrifugal flow and demister screen. |
| F-66Q (Oil-Stored) | 1/2″ to 2-1/8″ (e.g., F-6604Q to F-6617Q) | approx 102 to 165 | 2.0 to 7.0 | 3.3 to 13.0 | Combines separation with a large integrated oil reservoir. |
⭐ Features
| Feature | Detail | Selling Point |
| Superior Separation | Uses a centrifugal/helical path to spin the gas, followed by a stainless steel wire demister to capture oil mist. | Achieves very high efficiency (often >98%) with minimal pressure drop, even in long-line or low-temperature systems. |
| Low Pressure Drop | The spiral flow path is designed to minimize resistance. | Maximizes system capacity and reduces compressor power consumption. |
| Debris Protection | May include a permanent magnet at the bottom to capture ferrous metal debris. | Protects the oil return valve from mechanical failure. |
