Our workshop should have a dust collection system for woodworking.

A fixed system should be in place which has a couple of outlets with blast gates and flex hoses to connect wood working power tools as needed.

First pitch: 100mm PVC pipe under the roof along the brick wall with 3 down pipes (y-junction). Each down pipe has a blast gate and a 100mm to 50/35/?? mm outlet. Fixed, smooth pipe wherever possible, flex hose only where necessary. This ensures maximum flow.

Risk of sparks in pipes is considered minimal. If there are valid concerns concerning sparks, putting bare copper wire inside the tubes and ground them is a common solution.

If allowed, drill a 100mm hole in the wall and blow *filtered* exhaust outside.

Estimated material costs: ~200-300 €
