Auburn S220-3 DeAerator & Filter
The Auburn S220-3 DeAerator & Filter, also recognized as the Tigerloop Combi 3, is the definitive direct replacement for S220-4 models. This advanced oil de-aerator and fuel filter combination is engineered to remove up to 95% of air from heating systems. By integrating a 50-70 micron sintered plastic filter, it simplifies installation while ensuring a single-pipe system configuration between the tank and burner. This unique TigerLoopComboDeAerator&Filter design leverages a two-pipe fuel supply benefit, conditioning fuel by preheating it to improve combustion efficiency and eliminate common issues like oil burner lockouts, flameouts, and nozzle sputtering. Built with a maximum nozzle capacity of 29 GPH and featuring an integrated shutoff valve, the S220-3 Tigerloop reduces suction vacuum and protects your equipment from the risks associated with pressurized return lines. It is compatible with standard #1 and #2 heating oil and B5 BioHeat fuel blends.
Key Benefits- Enhanced Efficiency: Delivers foam-free, preheated oil to the nozzle for cleaner combustion and reduced soot buildup.
- System Protection: Eliminates the need for a return line, significantly reducing the risk of environmental leaks and contamination.
- Extended Component Life: Minimizes wear on the fuel pump and burner by reducing running vacuum and filtering contaminants.
- Simplified Installation: Combines de-aeration and filtration into a single, compact unit with an integrated shutoff valve.
- Lower Fuel Consumption: Optimizes burner performance, ensuring only the exact amount of fuel required is drawn from the tank.
Is the S220-3 compatible with my older S220-4 model?
Yes, the S220-3 is the direct technical replacement for the discontinued S220-4, offering identical fit and improved performance.
What should I do if the lower chamber of the Tigerloop is full of oil?
This is often normal operation depending on the installation height; however, oil should never be present in the upper safety chamber. If seen in the upper chamber, the unit requires immediate service.
Can I use this with 100% Biodiesel?
The S220-3 is rated for standard heating oils and BioHeat blends up to B5. For higher concentrations, a Bio-specific model is required.
