Is there a package deal for the CT AutoClean?
Participating dealers can offer a CT AC package deals with attractive savings on
CT AC when purchased with any tool, including the PLANEX Drywall Sander. See dealer
Does the variable suction dial on the PLANEX Drywall Sander require the CT AC to
The vacuum control does not require the CT AutoClean.The control on the PLANEX Drywall
Sander restricts air flow from the dust extractor as needed. At the right setting,
the PLANEX Drywall Sander will virtually hold itself to the wall or ceiling, supporting
its own weight.
Can you use the standard (non-AutoClean) CTs with the PLANEX Drywall Sander?
Yes, of course it's possible. The PLANEX Drywall Sander needs a 36mm hose which
is not included with the standard, non-AutoClean CT models. We have found some dust
will pass through the filter bag and into the tub and to the main filter. What this
means is that you may not get the full bag capacity because of a reduction in suction.
Also, your HEPA filter will likely get clogged with fine dust over time depending
on the quantity of dust produced. The AutoClean (High Performance HF-CT 496172)
filter will fit into a standard CT but without the automated cleaning functionality.
It would be possible to periodically stop, pull the filter, clean it through agitation
and put it back in to clean it manually. A standard 36mm hose will not have the
ability to use the locking mechanism that keeps the hose from wiggling loose. You
can buy the AutoClean hose separately, which is lighter and more flexible than the
standard 36mm hose (496972).
Can I use the CT AutoClean for purposes other than with the PLANEX Drywall Sander?
Yes, of course you can. It's a dust extractor. There is a dial on the front of the
unit that control the frequency of AutoCleaning and has a setting for no AutoClean.
So, it would function just like a regular CT. The standard filter is not HEPA. You
could install a HEPA filter into the unit, but it has not been tested for and
should not be used for EPA RRP
tasks. You can use filter bags in the CT AutoClean instead of the plastic
liners for capturing dust other than drywall dust.
What happens to the dust in the CT AutoClean?
The CT AutoClean is designed to be used with a plastic liner. It drapes over the
bucket/tub and be easily disposed of. The AutoClean can use standard filter bags
but it's not recommended for drywall applications.
Will the CT AutoClean hose work with all tools?
The CT AutoClean comes with a 36mm black, very flexible, lightweight hose with a
flange used to lock it onto the PLANEX Drywall Sander. It will not work with any
tool requiring a 27mm hose, such as sanders. It will work on all tools that can
use a 36mm hose, with the exception of the HL 850 which requires the hose to go
on the inside of the dust port. The AutoClean hose will not go on the inside of
the port because of the flange.
What is the difference between the HEPA filter and High Performance filter?
The HEPA filter will capture particles down to 0.3 microns in size whereas the high
performance filter does not offer that level of filtration. When comparing the two
there are some distinguishing features. The HEPA Filter has very tight pleats, a
brown seal on its sides, has "HEPA" written on it and is very rigid. The
high performance filter has much larger and more open pleats and is very flexible
to the point that it can be bent into a circle.
