My new Buggy will have 2 ARBs , & 4 free spool devices
The ARB pump will run it but i will run a 2.5Gallon air tank with a manifold to take all the fittings etc. The problem i had in the past was all the weight hanging off the pump with all the extra free spools etc.
Also with the tank we have fitted a connector so if the ARB pump fails {as it did in Croatia this year & Tay 2 years ago}we can plug the Quick Air 3 on it & charge the system.
I have a T-Max & fot VFM its great but will cut out after filling one 44 in the summer .The Quick Air will run all day & night ,fill a 44 from 4-154 in about 2 mins But you get what you pay for !
