Local business has 3x large extract fans that simply turn on and off with individual switches.
Can any brand of this type of fan be retrofitted with say, a ventaxia fan controller with speed and reverse?
Existing fans are Ziehl-Abegg. Photos showing existing wiring, and diagram on cover lid.
Note that the fan turns opposite to the arrow on the sticker…

It looks like it’s connected correctly… for one speed, one direction.
