Thread: JET 2HP Dust Extractor in a cupboard???

I saw pictures somewhere of someone doing something similar. They put a lot of ventilation in the wall and then sealed the extractor in, so yes, it is possible.

There's not much point in leaving the hose out the door if it is ajar, you will just be letting all the fine dust escape back into the room. The hose should be properly sealed into one wall of your enclosure using silastic or something similar. Any enclosure should be air tight to the internal side and ventilated fully to outside. The effect you are after is that the dusty is no longer part of the internal air envelope.

One concern with any sort of internal enclosure is what will happen when you go to empty it. Fine dust particles will have deposited inside your cupboard, so in changing the bag you will stir them all up and contaminate your work area.

One useful thought exercise I was taught when working with woodwork dust is to think of it as an invisible toxic gas. It's the invisible fine particles that do the most damage. They suspend in the air and deposit on you and your clothes and then you cart them inside to those indoors.

Here are a few ideas in my thread https://www.woodworkforums.com/f200/r...n-sound-46103/

I don't know why you can't vent outside but this may be a way around that. Run the exhaust of the extractor into a sealed cupboard and vent the cupboard through filters to the outside. The cupboard could be built into an exterior wall and the filters could be the size of the cupboard using panel filters. The air entering the cupboard would slow down and the dust would largely drop out before exiting through the filters. The exhausted air should be very clean doing it this way. The only major issue would be the periodical clean out but if you did it through the filter wall the dust would be outside the workshop. Carry this on further and you could put a pullout container in there that caught most of the debris and could be sealed on the top when removed thus stopping the need to shovel out all the debris. I think it would work rather well actually.
