Air fill manufacturer

Yong Heng

Yong Heng is the compressor that made home tank filling affordable, and it remains the reference unit for the entire budget tier. The pattern is consistent across its many labels: a 1.8 kW two-stage, splash-lubricated, water-cooled machine that needs a bucket, a pump, and an attentive owner, and in exchange fills a 6.8L bottle to 300 bar in roughly half an hour. It demands oil changes, cooling discipline, and an external moisture filter, and treated that way it has filled tanks for years in thousands of garages. Treated casually, it fails, which is the trade at this price.
