Air Pressure - Static PSI - VS - Working PSI

Hey everybody -

I put together a video explaining and proving the power differences you will get between using the incorrect air pressure & correct air pressure.

Pressure drops are caused by a number of things (air line size/length & air fitting size/type, etc). To gain the maximum (or even advertised) power ratings on your air tools, it is very important to ensure you have enough air pressure at load when your tools are being used.

In this setup I am using a 5HP 80 Gallon compressor, 1/2" air lines, and 3/8" fittings.

Very instructional ! I kind of knew the issue you described, but your visualization really brings it home !!!

I have to rum-age through fitting and maybe buy an extra pressure gauge and mike my self a setup to check my "working pressure".

How about a comparison of "working pressure" in your 1/2" hose 3/8" fittings versus the much more common 3/8" hose with 1/4" fittings ?

You are doing us a very big favor by testing out the products before we drop big bucks on them. So I subscribe and liked on your channel.

The term is dynamic pressure (velocity driven) or even total pressure which is the sum of static and dynamic pressure.

Glad I could help! And yep, I have that and other air-related (performance/upgrade) videos planned in the near future.

Thanks! I am happy that I can help!

I think actually showing what tools can do really helps people make informed decisions. Nothing worse than finding zero info online about a tool that you are looking at & having to rely on the manufacturer.

We have tested some of this. I don't remember the details about the small fittings which was some but the big deal is the size and length of hose. This is the place that 2 stage realy shines, it has enough head to be kicking in and maintain 140 in to the comp, just about the time a single kicks off.

I don't usually watch vids but that was good. I am not sure how much a swivel adds, didn't go to specifically test it but the big 1/2 gun on 50 ft of 3/8 needs almost 140 going in to the reel. He tested wit 1/2 which is significantly better, about 1/2 the loss. On a single stage system this could be a factor if the job demanded it. Change from 50 ft of 1/2 to 25 ft of 3/8 and the results are somewhat similar.

I think there is and could be more to this than informed decisions but there is a ton more you could do along the same subject and see whats the difference between 1/2 and 3/4 pipe on the main for 50 ft do,,, ha.
Its the advantage of 2 stage though, being able to turn it up to overcome loss. Not all loss is a tragedy, most is so intermitant and not every circuit is fully loaded. In only a few cases does the ultimate peak matter.
