Air fill manufacturer
Orcair
Orcair markets itself on being the smallest PCP compressor on the market at roughly 5kg, and the current Thunder model backs that pitch with a dual-fan cooled 350W unit that fills a 0.5L tank from empty to 4500 psi in 16 minutes. It was previously roster-listed in this database as an Amazon-native hand pump brand pending confirmation; that earlier reference was actually to this same company's compressor line, not a separate hand pump product, and is corrected here.
