Thread: How do I clean then setup a Festool Dust Extractor - CT 36 E AC HD for Kapex 120

1. Connect the CT 36's vac hose to the Kapex dust port
2. connect the Kapex power cord to the CT36
3. connect the CT 36's power cord to a GPO
4. turn the CT 36's power switch to autostart
5. switch the kapex


I think that is all the setup you need to do

WOW.
That looks way to simple after the hours n hours of research.

Do you mean gyprock?

Great question.
I'm not in the field.
So please excuse my lack of understanding.


This topic is only one of the many reasons my head still hurts like a hangover.
See the similarities under ChatGPT below.
No insult intended.



It's the super fine white powder.
That was everywhere.


I blew it out as best I could.


The long life filter
that came with the CL
is for wood chips only.
NOT for plaster.


I blew it out the long life filter
as best I could.
And used the 4" DE on it.
No matter how much I tried
It still had powder blow out.

After placing the LLF into the vac
I used the AC feature.
At first it still had blowout
but after a few pops
the blowout stopped.


Should I keep using this long life filter or change it out?

Are Drywall and Gyprock and plaster the same?




No, drywall, Gyprock, and plaster are not the same, although they are related.


Drywall is a building material that is made of gypsum plaster sandwiched between two layers of paper. It is commonly used for interior walls and ceilings in residential and commercial construction.


Gyprock, on the other hand, is a brand name for drywall that is popular in Australia. It is essentially the same as drywall, but the term "Gyprock" is often used colloquially in Australia to refer to any type of drywall.


Plaster, on the other hand, is a material that has been used for thousands of years in construction. It is typically made by mixing gypsum or lime with water, which forms a paste that can be applied to walls and ceilings. Plaster provides a smooth and durable finish and is often used in older homes or for decorative purposes in modern construction.


So while drywall and Gyprock are types of wallboard made with gypsum, plaster is a separate material that can be used to create a smooth and finished surface on walls and ceilings.

Do you mean the vacuum type -like used for hand held tools? If so get a new bag & "if needed" replace secondary filter. Good (compressed air blow out should fix check for holes as well!) Plasterers do horrible things to filters - very fine dust.

Barry
It's up to you.

The long-life filter is primarily designed for PM10 or bigger dust.
Plaster dust will [??] typically produce PM2.5 sized dust -- BobL can you please confirm this.



If it were me, the fact that you are no longer seeing dust suggests to me, that you have somewhat cleaned the long-life filter.
The really fine dust (PM2.5 and smaller) would be caught by the fine particle [HEPA ?] filters.
Does your CD 36 have provision for fine [HEPA ?] filters?

If yes, and they are not fitted, you may want to consider fitting them.

Sorry Barry, when considering a word meaning then quoting an American source or an artificial intelligence source may not be a meaningful approach.

Thanks to all who took the time and made the effort to reply.
Sincerely appreciated.

The Festool CT 36 E AC HD dust extractor vacuum is equipped with a HEPA filter, which is a high-efficiency filter capable of capturing very fine dust particles.

And even more evidence of my throbbing head concerning continents:

The filter that is supplied as standard with the CT36AC is rated to remove up to 1 micron whereas the HEPA filters go down to 0.3 micron. Unfortunately the most harmful particles are the invisible ones whose size is between 1 and 0.5 microns.

I find it strange that in Australia and NA the extractors are supplied with HEPA filters as standard but in Europe they only filter down to 1 micron, defined as L class which actually excludes wood dust.


The CT36AC HD is designated for wood dust as it has an M class filter.

Then

The Festool Long Life Filter is designed to capture fine dust particles, including those as small as 0.3 microns in size.

And yes:

The size of .3 microns is quite small, and it is often considered to be in the range of fine particulate matter (PM2.5). PM2.5 refers to particulate matter with a diameter of 2.5 microns or smaller. Therefore, .3 microns of dust would fall within the PM2.5 category.

I've concluded, hopefully, the .3 / PM 2.5 microns captured by both bag and HEPA filter is sufficient for capturing the find dust particles.


Should have mentioned that
I tapped HEPA filter to remove the large dust collected between the folds.
Then blew it out.
Finding no holes.
And looked to be in acceptable condition.

I did see where the filter bag is a bit worn and thin.

I've used the vac a number of times with the 120 and see no white puffs.

I wanna make sure I need long life filter before spending that kind of coin.
(probably need someone to tell me to stop mucking about and get one)

Thanks again.
