The small aluminum regulator you see on every control valve, positioner and transmitter in the plant
Walk around any refinery, chemical plant or power station and 90% of the instrument air regulators are Fisher 67C series. They’re cheap, they never clog, they hold set pressure for years, and you can get parts the next day. The 67CFR has the filter, the 67DFR has the dripwell for wet air. Maintenance guys keep a box of them in the store because when one fails you just swap it in ten minutes and you’re done.
