I have a dedicated 5 gal air tank that I will fill to 120psi in garage then bring in house to run silent. I don't yet know how long 5 gal at 120psi will run small Wilesco stationary regulated down to maybe less than 3psi. If I only get 5 min of run time I may have to rethink my system....I do own a small airbrush compressor that could be employed to fill the 5 gal tank.
