Dust bag

[Lonsdale73]

This is my dust and chip extractor, pictured in its old home. It's now in its new home (aka my garage) in what would be the diagonally opposite corner, about a similar height up. Being vertically challenged, I have to stand on tip toes or use a push stick to switch it on and hope I'm out of the way before the bag inflates in my face like an in-car airbag! Usually that's not too much of a problem. Bit harder is trying to reach over the inflated air bag to switch it off again; it's like trying to avoid James Cordon!

What I'm wondering is do I actually need this bag? I was thinking of maybe running a length of hose from the outlet to a barrel or box. Is this feasible or is there a very good reason for it having this type of cloth bag?

It filters the dust and stops it spraying back out into the workshop. Air has to be able to flow out of it otherwise no air would flow through your extraction system.

The exhausted air needs to go somewhere. The bag let's the air escape through the holes in the fabric, whilst trapping the majority of the dust inside. If you exhausted it into a box, it would either burst the box and spray the dust around, or it would create a reverse airflow back into the extractor, stalling it.

There's a couple of options.

You can use some pipe to extend the exhaust and have the bag lower down or to the side and more accessible whilst being out of the way.

You can get a simple three pin plug with remote, so you can switch it on and off without needing to poke it with a stick

Does the bag size matter?

Unfortunately the remote idea won't work as it has a built in NVR

 

[MattRoberts]

Yes - it needs a large surface area in order to let such a large volume of air out of all of the tiny holes in the fabric. You wouldn't want to use a bag any smaller than the one the manufacturer supplied. You can go bigger just fine, but I guess that won't help you much!

And you can use a remote just fine with a 13amp NVR switch - I do. Just cable tie a small bit of wood over the on switch.

I'd extend the wires to the NVR and put it down where you can get to it.

I've always been curious about your username, are you a fan of Vanian and co?
