Thread: Full Boar Dust Extractor

My testing shows that adding a chip collector to a small (1 and 2HP) Dust collector and in most cases even a 3HP is a sure way of initially collecting LESS fine dust and leaving it behind in the shed to accumulate - this is why folks that use chips catchers see so little in their DC.

If a given wood working process generates 100 units of fine dust, a 1HP (with a chip catcher) will only ever collect about 30 to 40 units of fine dust to begin with.

Adding a chip collector will reduce fine dust collection even further to around 25-30 units of the fine fine dust generated.

It takes some time before the benefit of the chip collector in protecting the filter makes a difference and during this time fine dust will simply not be collected and accumulate in the workshop.

Your'e better off not optimising the flow and not using a chip collector and emptying and cleaning the filter more often.

Most DC users let their bags accumulate far too much sawdust before they empty them - the collection bag should be emptied and filter cleaned when the collection bag is no more than half full and even less when its all fine dust such as generated by sanding.

Some time ago I was in Bunnies and saw the previous incarnation of the Full Boar Extractor for sale at $130.00. I thought that at that price it was worth the risk to try it out.

I use it on my lunchbox thicknesser and it used to get clogged up on the "safety grills" so I removed them.

The bag filter on top would always be covered by a thick layer of dust which was released every time I touched it or moved the machine. I replaced it with a pleated paper filter and don't have that problem any more.

I also use it to vacuum the floor whenever the thicknesser or router table make a mess, or I use a hand plane, and it occasionally picks up small offcuts.

These seem to go thru the fan with just a bang and, so far, no damage.

I use it for chip collection as the workspace is a carport and open to the weather fine dust is quickly blown away.

Agreed. As air filterers, these suck. No pun intended.

But for sucking chips out of a smallish machine to keep it running smoothly these work well... and a chip collector improves that performance. They're fine, so long as the operator doesn't delude themselves that there is any real level of healthy air filtration going on and wears suitable dust masks/whatever during operation.

After all, surely they'd be wearing them when operating the machines without the extractor? One would hope so, anyway.
