Running Kapex through extractor

[Mahan]

Hey all,
I am considering getting a Kapex and would like to run it directly plugged into an extractor. How many of you are doing this? What I don’t understand is that even on a 20amp breaker with the Kapex being 13, that only leaves 7 for the dust collection, which isn’t going to cut it. My Metabo asr35 draws 11 amps and full power. Am I missing something here? I run all my sanders, domino, etc directly through an extractor but those are all drawing much less amps. I have heard about all the older Kapex motors burning up because of this as well. Wondering if you guys can provide any insight. Thanks!

The current test I did a few weeks ago said the Kapex draws about 8.5 amp at speed dial #4 or so. The start-up was 16 amp.

My Kapex goes to a Dust Deputy first, then to a shop vac which draws 6.6 amp in full speed (start-up at 10 amp).

I've used the saw and shop vac with this auto-switch on two 15amp circuits for years:https://www.leevalley.com/en-us/sho...013-ivac-automatic-vacuum-switch?item=03J6210

That seems like a good solution. Thanks for sharing

You don't need the auto-switch if your plan is use the Kapex with one of the Festool extractors (CT26, etc.).

That’s true, I know, but that wasn’t even a question.

I’ve been running my Kapex through a Mini for years with no issues.

Another way around this is to get the Festool Bluetooth remote/module.  It’s $80. I run my Kapex and CT36 on separate outlets and the Bluetooth links the duct collection.  Just have the remote by the Kapex and turn the vac on and off as you need it with the remote.
