AOA also sells the Omega Air Charger for $1395 that's a possibility for the list too.
In all of my research, I also found the China manufacturer that makes something very similar to the Air Venturi 4500 110v compressor:
4500 PSI Compressor[/QUOTE]
https://www.airventuri.com/av/featured-products/compressor/embed/#?secret=OWheDve1op Don't know if these guys are the OEM manufacturer for Air Venturi's compressors, but they sure look similar. Here's a picture of the chinese version of the larger Air Venturi 4500 compressor. It's a 2 cylinder compressor weighing approx. 35Kg, 2.2Kw, 30mpa, 300bar, 4500psi unit. Says it'll fill a 6.8L bottle from 0-30mpa in ~30min.
This Chinese company also makes something that looks very close to the Air Venturi Nomad too as shown here.
Specs they provided are for this unit is: 12v or 110v power input, 350w, 5.5Kg, 30mpa, 300bar, 4500psi. It needs ~18min to fill a .5L tank from 0-30mpa.
I checked with them and if you order 5+ units, the larger model goes for $600 USD FOB China and the smaller one is $300 in quantities of 20 or more units FOB China. The name and address on their email is:
GUANG DONG DGS EQUIPMENT CO.,LTD.
Address: No.29, 1st floor, lian hua road, Changan town, Dong guan city, Guang dong provice of China.
I found these guys on Youtube demo'ing something that looked like the Air Venturi Nomad, so I searched for who they were and how much they wanted for it.
If enough members are interested, perhaps get a group deal going?
Thanks
