I already have the VIAIR 450p which is nice, but i want something fast that can also run air tools.

 

Decent product. .. just doesn't put out the CFMs at working pressure for most air tool needs.

It's a 10. Not running air tools. It's only used to inflate my tires

 

Found this from ARB:

Air tools rated up to 85LPM [3CFM] @ 6Bar [90PSI] continuous supply.
Air tools rated higher than 85LPM [3CFM] @ 6Bar [90PSI] using an optional air tank suitable to the run time requirements.

How much CFMs do u need for air tools?

 

My impact wrench is 5.4 CFM

ill call bs on that ! what air tools are they talking about that are only 3CFM !?!?!

my 1/2inch IR2131 is rated at an AVERAGE (not peak) CFM of 5 & its one of the more efficient impacts out there....get a crappy one from sears or chicago pneumatic (25cmf) and you can expect it to be even higher !

even my 3/8s inch IR 2115 is RATED at an average consumption of 4cfm - peaking at 17cfm (and you don't remove lugnuts w/ a 3/8s)

the problem w/ these OBA systems (even the good compressors) is the duty cycle, even w/ a small tank they cant be run very long...they would never be able to support an impact wrench even with a tank (mostly cause the tanks are too small and too easily depleted, let alone the fact that they dont have the sustainable psi (or the volume) needed !

 

does that include a tank ? thats alot of money when you consider you can buy a 2 stage 175psi regulator for less than 85 bucks
and run any tool you want & still have plenty of air for 90 or more tire FILLS (empty to full).

most of these portable air systems (tank types) are set to max out at 60 or 90 psi at the most, ive got a bit of a unique use case
(compared to most here) where i want to be able to quickly top off 110psi coach tires....i can do it w/ my coach on board air (150psi), but for as large as the compressor is (class 8 truck) it still takes a while (even w/ THREE air tanks).

for 80 bucks i picked up a 175psi duel stage (2 gauges) co2 regulator and am gonna put it on some tanks that i already own (picked up a 10lb tank at harbor freight for 20 bucks, that i just exchange at my local airgas store)...i can top off 10 truck tires (10psi) 45 times before i need to refill the small tank (14 bucks to refill) !

 

There's a lot of numbers flying around this thread

 

heres some more just for you

if anyone is interested in buying their own regulator i recommend the uniweld r1363 - its a 175psi adjustable C02 regulator.
the uniweld r1363 uses TWO gauges (aka duel stage) - i think its reasonable to WANT two gauges...one for adjustable output pressure and one to monitor the pressure in the tank (so you know when youre in need of a refill).

admittedly not every will want the 175psi limit (i got it because the tires on my coach require 110psi).

Ive found the uniweld r1363 for as low as 61 bucks (figures since i paid 80).

 

Nice thing about buying your own regulator is that you can just swap your tank at Home Depot for about 24$ (for a 20lb) at late hours.
