Upto now I've been using one of These to extract the dust from my blastroom, it sat outside in the yard under a cover.
First job was to move it inside
This reduces the noise level outside and keeps the heat from the motor inside. The flexible pipe connects to the blast cabinet and I've used a gulley to connect it to the side of the blastroom. The bit of pipe wrapped in gaffer tape is some flexible field drain. The tape is to block the holes and the flexible pipe isolates vibration from the wall of the blastroom.
I found that removing the rubber seal from an uderground bend allowed it to fit on the inlet of the extractor. This also allowed using standard soil pipe for the ductwork, instead of the overpriced proper stuff. The outlet is connected to the pipework with a toilet pan connector.
The next picture shows the original Clarke bag connected to the new pipework
The Clarke bag isn't that good, it lets the finer dust out and the seams are weak, so I contacted this firm http://multiplefabric who made me a couple of filter sleeves, 150mm dia x 1.5 m long :-
These are 5 micron mesh and the quality difference between these and the Clarke is amazing. Each is about the same surface area as the Clarke, and the two together allow the same airflow. The sleeves have a triple line of stitches down the length and the canvas is very heavy.
I've fitted screwed access ports to the bottoms for emptying:-
Because these are sleeves rather than bags the surface area doesn't reduce as a bag fills up.
I think in the future I'll add another 2 or 3 sleeves.
I've covered the whole thing with a plastic sheet to keep the sun and rain off, although when the final configuration is decided on I'll make some sort of a cupboard with sound proofing on the inside.
The sleeves weren't cheap, about £40.00 each with VAT, and the Multiple Fabric Company does like a £100 minimum order. Sleeves are made to order and took about a week.
