So if you go to this link:

5.5KW 18000rpm 220V Water Cooling ATC Spindle Motor for Machining Center Changsheng 120TD18Z5.5A [120TD18Z5.5A 220v] - US$3,150.00 : Fast To Buy Limited

and you scroll all the way to the bottom of it. You will see the inlet and outlet ports are labelled. There are 3 air ports that I can tell. It says "Tool exchange and dust removal" I'm guessing that means the third port is for "dust removal". Could this explain the air coming out of the bottom?

If I were you I'd write this seller a message and ask him for a user manual for this spindle, or at the very least to tell you the settings for a VFD or at what RPM it peaks at 5.5 kw. He sells them, so I assume he will know. Easy to contact sellers on aliexpress, just make an account and send him a message.
