How does fill speed compare to Yong Heng?

Takes me 25 mins to fill my ninja 77/4500 tank

If and when this compressor needs to be rebuilt is there a rebuild kit available and if so were can I purchase it and how.

Mine was shipped with extra o rings, screws, collars, small wrench. But the manual mentions nothing about rebuilds or replacing worn o rings. The manual is in "Chinglish" so it is poorly translated English. I think if it leaks or fails to work ur best bet is to see if Amazon or the manufacturer can facilitate some repair or replacement otherwise try fixing it DIY. For the low price even if it breaks down in 5 or 6 years u got ur money's worth.

So i’m being told this is the updated oil bath version and not the old grease version. so then, how often do you need to change the oil?

There is no oil change required. It's totally maintenance free.

Thx for helping with my question. Since the water and oil separator filter is built in, would you recommend putting one in the air line ??

Yes, I would highly recommend putting an additional filter on any air compressor as almost every air compressor eventually puts water inside your pcp airguns.
