220 CFM is off , the vac should be around 130 CFM . With the I-Pulse cleaning and no filter bags this vac is top of the line .Concrete , sheetrock ,wood dust ,plastic decking and blown in insulation are no problem for this vac . are these vacs generally used with no filter bag? just empty the canister? According to the specs, a bag is required. And I agree the 220 CFM must be a typo. |

For prolonged use for wood dust and shavings i use a fleece filter bag.....if i remember to install one . The overpriced plastic bags as liners are a waste of time and money for dumping the contents of the vac tub . The auto clean function on these vacs only work without a filter bag . link |

I'm not really sure if this post should be included here or not. I don't want to intrude upon another user's conversation, nevertheless the topics are similar, if not the same.
I've had a Festo SR5E for over 20 years now (on it's second motor). Made by Wap, it's also been marketed as a Stihl Se100, an Elu, and in a variety of other guises & liveries over the years. I've never felt the need to use (expensive) bags at all as I've had a "longlife" intermediate flocked cloth (needled felt??) filter suspended from the casing to separate the motor from the waste receptacle.
As it's been stolen, I'm looking for a suitable replacement. Something that is simple, lightweight, easily repaired and that allows the use of longlife pleated paper filters, wet & dry performance, a longlife bag or bag alternative such as the SR/Stihl uses and compatibility with my old Festo hoses & Y adaptors etc. Does anything from the Mafell/Bosch/Metabo/Starmix stable fit the bill? Or do I need to look for a used Festo CT33 or something?

I am seriously looking at this metabo vac to replace my festool ct26. I do not want to bother with costly bags but do not know if the bin lifts out for dumping or you need to tip the entire vac over to get the debris out. Or could i line the bin with an ordinary contractor bag if i just tear a hole where the port goes into the bin. I will get a reusable fleece bag but do not want to use that for fine drywall dust or concrete dust i would only use that for wood saw dust and shavings. |

The bin is attached similarly to the Festool ones, and doesn't function much differently. It's just the dual auto clean filters that lets you tackle non-wood materials without clogging the filters. So yes, you can just poke a hole in a bag of you wish, or not run a bag at all, both work fine. |

The auto clean function on these vacs only work without a filter bag . linkIs this definitely correct? I understand that the autoclean will protect the motor by frequently clearing debris from the filters, but there's still a (conditioned) part of my mind that feels wary of using an expensive extractor (over the longterm, I mean) without a conventional semi-porous bag to capture 75% of the dust before it even reaches the filter(s). Hundreds (perhaps thousands) of people have killed their Numatic Henry vacuums because they were too lazy/tight to use a bag and the dust eventually killed the motor. I totally grasp that the Henry lacks auto-clean and that that is a major factor, but I only mention it by way of partially explaining why I am so conditioned to use a proper semi-porous vacuum bag in any and all vacuum extractors, regardless of how well their filters are designed & implemented. So... with that said, I return to my above question, since I would > prefer< to use an autoclean Starmix with the extra protection of a legitimate semi-porous bag. If I buy a Starmix (or licensed equivalent) will I be forced to omit any such bag in order for the filter-auto-clean functionality to work correctly? Cheers. |

it is most definitely correct. this is how all these vacuums are supposed to operate.
option A: you use a closed bag and no auto filter cleaning mechanism.
option B: you don't use a bag or an open liner bag with the auto filter mechanism active.

Wow, and this doesn't lead to motor damage from fine dust ingress, in the longterm?
I'm honestly very surprised by that, as, no matter how frequent the auto-cleaning, there must surely be a small percentage of dust making it through the filter, with such powerful airflow.

Whatever gets through the filter gets through anyway.
You could use X amount of bags all wrapped inside eachother, it doesn't change a thing.
At the end of the line, the filtration of the bags isn't as good as the pleated filter and thus the fine dust passes through a bag anyway.
The difference is your pleated filter gets contaminated much faster and has a less longer life span.
You can use bags for coarse dust, but when you deal with very fine stuff like for example cement, using a bag is totally counterproductive in my experience. The bags cake up in no time and you vacuum has no suction, defeating it's purpose.
I use bags for coarse wood dust from saws, open liner with autoclean for MDF and the stuff off grinders and the like.
If I have enough room I prefer to use autoclean with open liner and dust deputy combo. I've found that the fine stuff that doesn't get take out by the dust deputy cakes the bags too fast for my liking.
You can charge your clients for new filters and fit new ones for each job...

Thankyou, Jonathan; your above explanation makes rational sense.

This has not been my experience with the L-1635, in fact I was advised (by Allsaw) of the exact opposite, and told that
most users of these iPulse models prefer to keep the fleece bag in and with the autoclean on - which sounded distinctly
counter intuitive to me at the time.
However experience of using this method, has proved it to be effective at filling the bag to its capacity; keeping it
relatively unclogged (the alternate agitation of the filters works to loosen dust caking the interior of the bag); and
saved overtaxing the filters.
The problem of bags caking up I have experienced, along with filters getting over contaminated with dust not
caught by the bag and extractor overheating - this is exactly what happened with my Festool Midi*, and after a fair bit of
research, I decided on the Starmix which performs exceptionally well in all applications I've thrown at it, from sanding
drywall filler; grinding concrete/render using a renovation tool; cutting timber. And although heavier to lift
(especially when bag full) is easy to move around with attached handle.
*Have to say Festool when you read the literature, Do say the Mini and Midi (and of course the Sys) are not suitable for
anything but light duties. Not sure how many Mini and Midi buyers would have been aware of that restriction?
And I was definitely mistaken when I thought my new Midi would out perform my 17 year old CT11 (finally sold on to a
carpenter friend for his workshop, still performing well a year later) - in fact it proved to be the other way around.
And further, Festool make it clear, if you want something that'll handle most types of dust extraction, your best off
getting an AC model. I just concluded the Starmix iPulse tech was superior to the Festool AC :
I also preferred uninterrupted suction, and the fact I could fit Hepa filters into the Starmix, neither of which is possible with
the Festool AC models.

I dunno... I think the green tools pretty much suck. |
