I agree there are ways like side entry that can improve efficency without having to spend a great deal of money to get improvement. I have already forked out $27 for a 90 degree 150mm right angle bend, and I have a 150mm inlet on the DC, so all I really need to improve the existing extractor is to buy some 150mm flexible pipe and clamps.
Surely removing the 4" hose / 90mm DE outlet and replacing it with a 150mm outlet pipe / 150mm hose has to improve increase both vacuum and flow until I have chance to redesign something more efficent. I dont recall seeing anyone mention previously having a larger outlet than inlet before but it does provide food for thought.
