hose between cyclone/60l bin and tools

[vjekob]

I'm planning to install a central dust collection system in the future as I have a couple of tools
with large dust ports/collection needs, but for now I have a Kaercher dust collector (non anti-static)
and Dust Commander cyclone with a 60l metal bin. I need to buy the hose on the cyclone tool
end and would like to use it with an overhead boom and have some anti-static “functionality”.

Couple of questions:
(a)If cyclone port is above working table height and table is approx.. 2.5m long, would a 5m
hose be sufficiently long ?
(b) I was thinking of getting something like the Festool 500684 D36 5m antistatic hose which
costs 140Euro here. Would an antistatic hose help in this situation/ would I need copper earthing
anyway ? What are the actual inside and outside diameters of the connectors on the ends of
the hose I mentioned – can I find this information anywhere ?

All Festool hoses have a 50mm outer diameter (very slightly tapered) connector on the vac side end.

Needed length for the host can easily be found out by using a string, add some to the measured minimum for needed corner radii, add a bit more to be on the safe side.

To ground the hose the simplest is to attach an antistatic wristband (electronics supply for single-digit amount of €) around the vac end connector (as it's conductive) and connect the wire to a known good ground.

Using an antistatic hose between the tool and a cyclone with an otherwise non-antistatic system is a mistake, from my experience. The cyclone will generate static and with an antistatic hose between it and the tool, the static will find the path of least resistance which is to travel to the tool and on to your hand. Rather annoying while you are trying to work. So, you should either not use antistatic hoses with your non-antistatic setup, or you will need to provide a complete path to ground.

Thanks for the replies ! Looks like I'll stick with normal hoses then as whatever I buy
in the future, won't be completely anti-static from ground up and adding some wire/grounding
makes more economical sense for my home setup.
