Hilti has come out with a new dust extractor vacuum, VC 40MX-CB, and its continuous collection bag system looks to work a lot like a diaper pail.
Diaper pails work with extended-length bags, perhaps better described as long plastic sleeves, that are condensed into a ring-shaped cartridge. After sealing the bottom, you fill it with diapers, and then when it’s full you seal the top of the bag and cut it from the rest of the plastic sleeve. Seal the new bottom end of the sleeve, and you’re ready to go again.
The Hilti vac’s continuous bag system works in a similar manner. After the dust extractor vacuum fills up the collection bag, you pull it out a little bit, seal the bag with a zip tie, seal the bottom of the sleeve with another zip tie, cut the full bag from the clean sleeve, and you’re ready to go again.
Here’s a closeup of the continuous bag.
The continuous bag collection system can be used with Hilti VC-20/40/150-X dust extractors, and only for dry pickup.
This seems like an interesting and convenient way to handle jobsite dust and debris collection. Hilti says that, not only does the continuous bag system help with quick changes, it helps reduce dust exposure, and avoids the need to remove the vacuum top.
Users can also check the collection capacity at a glance.
I really like this idea, and how it compares to a lot of other emptying methods.
Hilti USA has not made any announcements in the months since the new vacuum system launched in the EU, and so it’s unclear if or when it’ll be available here.
Looking deeper, other brands launched dust extractor vacuums with similar continuous bag collection systems before, such as Husqvarna. There could be others, but I’m not finding many mainstream examples.
Continuous bag collection systems, such as by Longopac, have also been available in other industries.
In other words, this is new to me but the idea is not new-to-world. I’d like to see more dust extractor vacuums and collectors with Longopac bagging systems – this seems like a great combo.
Here’s a video of how it works:
