if you understand the industry then you would know most are made by the same factory. companies buy them and stamp their names on it. i know that higher end brands like badger,iwata and what not do not do this and actually build their units.
No, Neither Badger nor Iwata build their compressors. Badger used to sell Thomas (built in USA) compressor under their own brand, but is now sourcing their Badger compressors from China. Iwata has used Sparmax in Taiwan as their manufacturer for many years and built a good reputation for reliability.
The many Mom and Pa factories in China are another story. They may look similar on the outside, it is the inside that counts. The cylinder wall coating and piston rings of oilless compressor need to be manufactured to tight tolerance to keep noise low, heat minimal for a long service life. Fenghua Bida has steadily improved their compressors in recently years, but not necessarily the other Mom & Pa shops. Fenghua Bida is rumored to be the Airbrush-Depot and Badger supplier, but not confirmed.
