Hey guys, here is a little comparison test video I have put together testing the difference between inflating your 4wd tire from 15psi to 35psi using the conventional method with your valve installed vs the Milton 3 in 1 Inflator vs the Airtec Inflator/Deflator.
This is my first video presenting to the camera so cut me some slack. :) Sorry for the low quality audio and background noise, ive got a better microphone coming. We have quiet a large compressor fitted to our vehicle as well as a 15 litre airtank however we do feel you will acheive a decent increase in speed even with a smaller compressor due to less flow restriction trying to inflate past the tire schrader valve.
