Blowing out 800' of 5 inch pipe plus a 39m takes 11 minutes AIR ON!!!!

10 inch slump just before seperation with a 375 air compressor and still takes that long, gets a Lil nerve-wracking

In my opinion just another idiot that shoot stay away from air cleaning. If you don’t understand the basics of air cleaning stay away from it. This was a 5 cubic yard air bomb.

Hey superdoffer were you there? Do you know the conditions of that jobsite? Do you know what has happened on previous blow downs? If you don't then stop ASSuming you know the sutuation. 

I just  imagined what happens if the guy had the gasket of his last elbow replaced the day before?  

And them. A 375 compressor and air controlle??

There's nothing wrong with that. We do it the same way.

In my opinion it is never smart to ''play'' with air in concrete line. You should always have control. Not just put the compressor on at full power and see what happens. If you have seen enough you know that realy scary things can happen with air. Specialy in an almost 1000' long line with a huge compressor on it. Strange that so many don't realize that..

Pretty sure u can check how lose ur tip elbow is when u take off ur tip hose and it looks to me like it didn't move an inch. As for the video the only thing u see is the boom so u have no idea how this was done. They are a good group of guys and I know they know what they are doing And understand the dangers of using air. 

All i know is people got killed by to much air pressure in concrete line. If everything goes good its no problem. It unexpected thing that can make problems. And than you have a potential bomb on your buildingsite..
