SF6 gas compressors

Complete oil-less piston compressors for SF6 gas handling, recovery and refilling, in four standard models covering roughly 6 to 80 Nm³/h.

SF6 is expensive and tightly regulated, so the whole point of the machine is to move it without losing any and without putting oil into it. An oil-lubricated compressor cannot do that job at all, whatever its flow figures look like.

Four standard models cover the common duties. Anything outside the chart is sized to your duty point rather than rounded up to the next catalogue machine, because oversizing an SF6 compressor wastes power and complicates recovery at low pressure.
