Recover, Recompress, and Reuse SF6 Gas Safely and Efficientl […]
The PUFCO Oil-Free SF6 Gas Recovery Compressor is specifically designed for the recovery, recompression, and transfer of sulfur hexafluoride (SF6) gas during the maintenance, servicing, and refurbishment of high-voltage electrical equipment. It is widely used in SF6 circuit breakers, GIS substations, gas-insulated switchgear, and electrical utility maintenance operations.
With a completely oil-free compression design, the compressor ensures contamination-free gas recovery, helping operators maintain gas purity while reducing operating costs and environmental impact.
The oil-free reciprocating compression system eliminates the risk of oil contamination, ensuring recovered SF6 gas remains clean and reusable.
Designed for rapid gas transfer and recovery, minimizing maintenance downtime and improving service productivity.
Heavy-duty industrial components provide exceptional reliability for continuous operation in demanding utility and industrial environments.
The fully balanced compressor structure reduces vibration, lowers mechanical stress, and extends equipment service life.
Available with both air-cooled and water-cooled configurations to match different installation environments and project requirements.
Compact skid-mounted design requires minimal foundation work and offers convenient access for routine maintenance.
Energy-efficient operation combined with reduced maintenance requirements helps lower total lifecycle costs.
Typical Applications
Recover and recompress SF6 gas during inspection, repair, and overhaul operations.
Support gas evacuation, transfer, and refilling processes for GIS equipment.
Used by electrical utilities, transmission operators, and maintenance contractors for high-voltage equipment servicing.
Integrated into SF6 gas recovery and purification systems for gas reuse and environmental compliance.
