Frequently Asked Questions
What is an SF6 recovery compressor?
An SF6 recovery compressor is a specialized gas compressor used to extract, compress, transfer, and store sulfur hexafluoride gas from electrical equipment during maintenance operations.
Why is oil-free compression important for SF6 gas?
Oil contamination can affect gas purity and insulation performance. Oil-free compressors ensure recovered SF6 gas remains clean and suitable for reuse.
Can the compressor run continuously?
Yes. PUFCO SF6 compressors are designed for industrial-duty 24-hour continuous operation.
Is customization available?
Yes. We provide customized flow rates, pressure ranges, cooling methods, control systems, and electrical configurations based on customer requirements.
