air venturi nomad 2 filling fx m3 580cc time?

hello i am new her and ive been into air guns for about a year i am wanting to get a FX impact m3 here in the next few weeks i am also looking for a new compressor i currently have the lil cheapy yong heng compressor and i don't believe it will work on the fx impact m3 to fill all the way and i just do not trust it with that expensive of a gun with the condensation blah blah blah lol so if i get a nomad how long does it take to fill from empty to full if any one has any input id greatly appreciate it thankyou and i know once you fill it and set the reg pressure you cant go below the reg pressure so id only be filling from what like 150 bar to 300 bar in a 580 cc tank after i fill it to full the first time so at least thats good lol (less time) any other compressors under 1500 worth it an easy use you would reccomend ?
 
Don't have a FX impact, do have a Nomad II. Do not recommend it to fill the FX, don't recommend it to fill a Crossman, Hatsan or even a BB gun. Too much money for a product with very little support WHEN it goes bad.

I say that because in all the time the unit has been out AV (or the actual builder - whoever that may be) have made NO effort to offer any type of customer self repair help.
