air hose reduced flowBest practice on air hoses is to use rigid plastic pipe, ie 4" waste/soil pipe and fittings and only use the flexible hose for the last meter or so to attach to the machine/extractor.

Not impresiveThe overall quality is very good, however in a 5 meter hose connected to a 950m3/h dust extractor, doesnt work good. The air flow is reduced almost to half!! It creates a lot of air resistance.
