What is the maximum effective length of a hose for a CT22 Dust Extractor

[Frank Pellow]

I have more than one application where I would like a 27mm hose with a length of between 10 and 12 metres and I know that it is possible to connect hoses.

But, I see that the logest hose Festool sells is 7 metres long.  If I bought one of those and connected it to a 5 metre hose on my CT 22, would it still be effective.  If not, what sort of reduction in suction should I expect?

i think jmb tried this in his mothers house to hoover the place . it didnt work well . i would use as much 50mm and 36mm as posible to keep the resistance down. if you were sanding it might work but not well if there was chips being made

Your CT22 included a 3.5m AS hose. Festool also sells a 27mm x 5m AS hose cat 452 880. The most effective way to extend the hose on any Festool CT is with the 50mm x 4m cat 452890 using an Anti Static connector sleeve cat 493 047. It is entirely practical to connect 2 of the 50mm x 4m AS hoses to a 27mm x 5m AS hose, for a total of 13m. Doing this requires 2 of the AS connector sleeves.

My experience has been that this combination still provides enough suction for any Festool which will function with a 27mm AS hose, such as the sanders, Domino, jig saws, OF1010 and MFK700. The larger routers OF1400 and OF2200, the planers and the TS55/75 all need the 36mm AS hose.

Thanks, I should have mentgioned that the application is sanding (with a bit of clean-up as well).

Thanks, that is all valuable information.

It is possible to do some light cleaning with a 27mm hose, but cleaning is far more effective with the 36mm hose.

I got a hose I think it was 17meters NON-AS as festool makes hoses to any length you want  they charge by  metre your better doing that than connecting.    I was told 17metres would be fine but festool recommended no more than 15metres really.   Any way the suction loss at 17metres was about 50% I recon or moro!  so if I was to cut it down by 2metres to festools recommendation I don't think it would of improved it much more so I sent it back on the basis false information.As they said no suction loss at 15metres  you cant tell me 2metres would of made da much of a difference.

I tried a 4metre 36mm hose on a air powered brush and it turned it so fast it would whistle and it was very difficult to stop the spining brush with your hand.  I tried the same air powered brush head on e 17metres 36mm hose and it was hardly spinning I could stop the spinning brush with my Tongue if it was clean it would of shown a video stopping it with my tongue lol so I recon it must be at least or more than 50% suction loss for the air powered brush to spin so slow and weak.
