I continuous blend, up to and including 40%, through my compressor all the time. Over 120 hours this year alone - and no issues. I use the appropriate and recommended oil. I know dozens of people that do the same. I trust the Oxyhacker book since thousands of us have replicated Vince's designs and taken his recommendations.

This is a Mariner/PE200 in a Live On Board (LOB) vessel, doing continuous blending of nitrox probably to 32%. The compressor room is not the coolest, sharing with main engine room, albeit lots of cooling blowers assisted, still I would guess ambient temp is easy 35 - 45C most of the time.
High oxygen level is a strong oxidizer. This compressor uses P21 ( P Zero for USA boys ) combo final water separator filter tower. The compressor did not explode ( yet), but its life is very short.
See how the P21 plastic filter cartridge melting and blue color wash out even stain the HP seat of the final safety valve. Yes HP seat cracking too, too much heat.
