Just wanted to let everyone know NOT to buy this compressor:
Look closely, it's NOT the Q-industry/Master Flow 1089 style compressor. It's smaller and here's the worst part - the head and cylinder "heat sinks" are fake. They're not part of the cylinder wall and cylinder head, nor are they physically connected to them for heat conduction.
I fell for it, bought one, then end up ripped off the fake heat sinks. The bare compressor underneath looks like a clone of the Viair 98C:
Most of those twin cylinder compressors claim a 40 min duty cycle (66%). I highly doubt it and call it false advertising. Such a duty cycle is impossible without proper heat sinking. The Viair is rated at a much more realistic 10 min (17%) duty cycle.
Would it work for the occasional tire air-up? For sure, but not for airing up 4 off-road tires at a time.
