Solutions used to say 325 cfm and 425 with the booster fitted

Its the 10hg vs 16.5 thats significant ...    ( thats 135" lift vs 230" lift )


As for CFM it has three motors ... each around 100cfm   ,  same motors thats in the airflex turbo on youtube showing  305cfm , scorpion had quite restrictive plumbing so around the same or less ....
An inline booster wont raise lift significantly .

These CFM figures, how are they calculated and with what length of hose?

Simon im quoting Mytees figures at the machine .
325CFM   230" lift
I believe an ETM like this would be mostly used in the 100ft max range in domestic situations anyway .
At 200ft i believe its dropped to  125cfm and 175" lift measured at the hose .
Still a fairly usable figure but at 200ft Mytee would probably expect you to add the Twinvac series Airhog booster ( 230" / 150CFM ) close to the wand .... which could double as your backup standalone portable with the additional water box .

Of course not as powerful or convenient as a large truckmount ...  but you've gotta make these things work for you and live with any compromises .
