with 22.5" wheels at 100#, i don't air down
i have the Tsunami MF1050 from "Q industries" similar to the MV50
it was mainly used on air bags and motorcycle tires
i have owned it about 9 yrs, used it a lot this last month,
one rear tire kept loosing copious amount of air
when i finally get into the truck tire shop
i found out the wheel was bad, leaking air thru the steel "rust cause porosity"
$368 later i have a replacement Alu alloy wheel
the duty cycle on mine is 40 minutes at 40#
you can air UP all the tires on your avg car truck jeep, in less time than that
my MF has also been modified to use a regular 3/8 air hose via quick connect, and i have requisite hose, air chucks , tire gauge, etc..
