Hello everyone

as I wrote in a previous topic, I moved into a bigger shop last year. I kept my original dust collector and system and only added some main duct to fit the shop. I took a decision not only because I ran out of budget with the rest of the machines and I wasnt sure that this would be the final layout of my shop and needs.

My system at this point has a 1stage, 2hp, 30cm impeller,125mm inlet, filter bag and run 125mm main duct and drops to machines.
As you will see in the photos I have the dc in a seperate room along with my lumber storage for saving space and noise. Of course I know that this sucks a lot of air from the workshop but living in Paros, Greece I use a small workshop heater for less than 10-15days a year so its not a problem. The room is 280cm tall and the collector will be places right after the door at 200cm height of inlet.

Now in european market we dont get a lot of ready 2stage collectors so my options are including shipping to my door and added remote controll system when not included:


Oneida Eu-export V-2000 2600euros
1-phase 2hp, 38cm impeller, tall cyclone

Laguna Cflux 3 1750euros
3-phase 3hp, 39cm impeller, short cyclone

The next options are not a ready kit:

In Europe we do have a several type of Cyclones that are coded and produced with certificate, in out case its the JA type:

The JA 20 is really simillar to Bill Penz EF5 separator in size (a bit taller, but a bit less in diameter) and I have asked a local company that can make me one from 1.5mm galvanized steel for 650euros

And either use a ready system like Bernardo DC-650 1360 euros

But I can also buy a radial Fan and build it my own saving space and money and actually with good separation I can even blow out of the shop the fine dust.

I guess any of the following will do the work

https://www.krollit.com/en/ventilato...ifughi-rv-403/ 850euros

https://www.krollit.com/en/ventilato...ifughi-rv-400/ 650euros *this is on the DC-650 above

https://www.krollit.com/en/ventilato...fughi-rv-5500/ 650euros


and the cartige filter is at 260 euros /piece

As for ducting I plan to to either of going with 160mm or 200mm main duct and reduced to 125mm before blast gate and flexible hose to the machine with 2 45degree and 40cm straight pipe between them.

I know that it's stated a lot of times that the bigger the main the better, but Im a bit concerned that the transition from 119mm to 194mm -those are the inside measurments of the pipes- will reduce the velocity a lot.

The following photos are the optimal drop in my workshop now, the main duct and the layout.
