First Stage for shop air blower ..

Is that the mk5/10 clone?

No idea! I'm not up on all the brands and identifying them. I *think* it might be a DX2, post 1995 based on one doc I came across. Though the one I have is chrome, not brushed finish... It doesn't have a bottom port like the SP MK10 seems to have.

I haven't taken it apart - it seems to be locking up well enough - checking for IP creep now that I have a way to vent it. I have the IP set to about 125psi.

LDS had a clearance on HOG D2s that they ordered for a local public safety dive team. They ordered DIN regs but when they came in decided they meant to order yoke regs... (Why? I can't figure that one out!) But, I got a couple of those HOGs.

Coming off the first stage, I stuck on a small variable pressure regulator from Ingersoll-Rand. Because while I am usually of the "MORE POWER" school of things, sometimes I don't need 140 PSI. I stuck a schrader valve off of one of the LP ports to make it easy to drain if I don't have anything hooked up to it and the valve gets turned on (saves me from having to hunt down and plug in a hose w/ air gun) as well as a button SPG on an HP port. I have one of these at a bottle at the scuba bench and one at the gun cleaning bench.

Sometimes I prefer a bit more pressure than is available through a regulator

No opv

Over-Pressure Relief Valve (User Adjustable)

The over pressure relief valve (OPV) screws into any available first stage low pressure port and provides protection from first stage failure.

Here’s mine. Scubapro MK200 I rebuilt, flipped the HP seat, all new O-rings. The local hydraulics shop had all but one. Ordered the rest from Grainger. Used a el cheapo HF coupler. I need to put a small ARO-style reg on it to drop the supply pressure down to 90psi.
