Triplex Compressor
A triplex compressor is a stationary, building-sized aethercompression pump. They were invented in 346 in Arkandic engineer Goran Feldt and became the standard depot compressor after the Triplex Crisis led to the nationalization of the patent.
They compress to blue-grade density.
an important thing here is that triplexes are not the first industrial compressors. theyre just like the size of a small windmill instead of requiring an entire factory. they also fill user-supplied canisters instead of barrels so theyre like a consumer-level infrastructure thing
