Filling a 6.8L tank

I have a Nomad 2 pump which has been fine for filling my PCP bottle on the gun, but recently bought a 6.8L tank to keep me going if I'm at the range. What would be a good compressor to buy (preferably not too expensive) to fill the tank with? Can it be done with the Nomad only using it for 7-8 minutes at a time?



Don’t do it. It’ll fry, if not by the second time it will by the fourth time. Do a search on nomad 2 failures from filling tanks. I believe the longest I’ve read in the forums one has lasted filling tanks is 6 months. In that 6 months, it was probably his 6th top off. 

Those compressor types are made for filling and topping off guns only.
