Changing the hose diameter on a Midi vac ?

Hi FOGers,

Sorry I'm not a regular poster but I thought this topic would be of interest for some in the same situation as me.

Also, please accept my apologies since I'm not a native english speaker and sometimes my sentences can possibly be written "weirdly" [emoji28]

I currently own a TS55 Rebq connected to a Festool Midi vac. So far, so good [emoji6]

I've noticed that closing (with duct tape) the rectangular window that shows the blade locking nut can ever so slightly increase the suction power (ok by a small margin in fact).

I have the original hose 32/27mm and wondered if it would be a smart move to remove this hose completely and put a 36mm hose all the way.

From my recent searches I understood the following:

- there is no angle adaptor for the 36mm hose so doing so will not allow any systainer to sit on the Midi vac since the hose will protrude vertically. No big deal.

- I was thinking of having a custom made hose of 2.5 m lenght since I find the 3.5 meter long hose a bit difficult to manage or maybe just too long.

- still wonder if a 2.5 meters long hose of 36mm diam would fit in the hose storage part of the Midi vac.

Please share any opinion and input. More than happy to hear what you guys think.

Chees boys.

 
Using the larger hose will increase suction.  Personally I wouldn't shorten the hose.  Perhaps someone else can chime in on whether or not a shortened hose will fit in the hose garage.

Thanks Peter. Also the reason for a shorter hose is that it increases suction too. I was also thinking of trying to find a hose in which the inside is smooth rather than ribbed
 
    I just tried my 3.5 meter D36 in the Midi. I was able to jam in about 2 meters. It was tight and no way was another .5 meters going in.

    I think a hose that isn't ribbed inside will either be too flexible (crushable) or too ridged.

Hi SrSemenza,

Thanks for that info, very helpful indeed ! May I ask you which hose adaptors you have on this 36mm hose (on the vac side and on the tool side)

Thanks mate

  No adapters. I have a shortened D36 (about 1.5 meters) that I use to connect the Mini to the Kapex. That fits nicely in the hose garage. But I used my 3.5 meter D36 hose to test it out for you. I had a meter plus left when I got all the length I could into the hose garage.

    If you really want to get a long enough D36 hose into the Mini / Midi garage, then you will need to extend the garage height. A systainer with the bottom cut out, latched on top would work. 

    I find the D36 hose does improve DC over the D27 , but only marginally on the TS55. I don't know how it compare s to the tapered hose.

hi im also interested in this. may i just ask when you tested it did you also have the power cable in the hose garage or not? as i was thinking if you were to un hook the d36 so it wasnt going in to the extractor vertically and also left the power cord out the hose garage (possibly create a power cord reel thing for the back of the midi) then surely you could get a decent length of d36 stored in there?
 
Too bad i cannot try out the D36 hose with the Ts55. As SRSemensa pointed out, the suction improvement might not be as much as I would expect. I probably have to give it a good think before I reinvest in a D36 hose

  Good catch I hadn't thought to mention that info in the other post.  No power cord. And I did disconnect the vac end form the port. It would be much harder to get the hose in with it connected and even less would fit.

@ SRSemenza: oh by the way, I always write you name " Sebenza" (kind of a folding knife lover Freudian slip  [embarassed] )
Ok so where were we ? Ah yes, in your opinion, how would you rate the suction factor of the Midi with:

- Factory default tapered hose in 32mm (vac) / 27mm (tool).
- New 36mm hose.

My take is that the hose would be larger in diameter but not only that, the adapter on the tool would go around the tool port and not inside (don't know if what I've just written is clear).

So in your opinion, would you say that you have much less chips and dust while sawing or the difference is rather minimal, hence not "really" justifiying the purchase of this larger hose.

The reason why I'm asking you is because is will be a 100€ investment in the end and I want to be fully aware of what this implies. If it's a major improvement, I can pull the trigger but if I will probably sweep the floor (once instead of 4 time  [huh]) anyways...well I can probably stick to a small broom with me.

What's your thought ?

Thanks
 
    I don't have the tapered hose. So I can only offer a real comparison between the D27 and D36 non-tapered hoses.

    I would call the suction difference on the TS55 minimal. Some will say it is more  than that but the terms we are using are subjective. However I don't think anyone would call it major. That being the improvement by using the D36 over the D27.

    I have not felt that the improvement warrants dealing with the less flexible larger hose for the TS55.

    Yes, the D36 fits over the dust port.

    If you have plans on a Festool router , Kapex, or planer ....... those tools do see a major improvement on dust collection using the D36 over the D27. It is nicer for floor cleaning simply because fewer large pieces get stuck at the nozzle. Mostly it is 2" or longer splinters that get stuck on the D27.

    My inclination from what you have described would be to hold off on the D36 until you  have a tool that would be noticeably improved by using it.

Words of wisdom, couldn't have been put in a more clearer way. Thanks SRSemenza !
 
hi just let you know i went ahead and bought the larger hose i made some hooks up for the power cable and cut 400mm of the new hose (so its now 3.1m) but for my need this is the best option and am pleased with result.

will cut the hooks off a bit and respray them as they do stick out a bit as they are
