Chamber fan full tech data

Hi to all!

Could someone, please, provide full technical data for chamber fan (in my case it’s Snowfan YY9225L24S in P1S)?
I have seen this page: Chamber Temperature Regulator Fan, but this not enough to me (no dimesions, no pressure, no Flow-Pressure diagram etc.). Also tried ask Snowfan directly, but still no answer in a week.

I’m looking for replacing this fan to something more efficient in terms of perfomance.
