4 sider extraction

Post by davidpidge » Sun Jun 21, 2020 4:07 pm

Hi all,
Got my sintex XL coming in a couple of weeks. I got a twin bag, Felder AF 22 extractor that sucks 3100m³/h. It's a used machine from another woodworker and I could still give it back to him if it's not up to the job. So, anybody know if I should get a bigger extractor?
The extractor will only serve the 4 sider and no other machines. If it makes any difference, the felder inlet is 160mm and the sintex has 1 no. 160mm outlet and 2 no. 120mm outlets (all will go into a 3-into1 manifold)

Hi David,
Have you tried looking online for the specification for the machine as it should state the minimum requirements for extraction.If I remember correctly my Paoloni RD240 required around 4000 M3/HR. It has 1x200mm port and 1x150mm port. My guess is it depends partly on how much each head can take off in one pass , mine will take 10mm off each head (never go that far but regularly 5mm) which is a fair amount of timber so my gut instinct is you will need a bigger extractor . I have an old 2bag P&J which is around 4000 and it works ok but could do better.

I recently bought a 2 bag Powermatic from Axminster (No a fan of the company but needed one quick) for my mitre saw and rip saw which has a rate of 2,800 m3/hr and Its ok for that but I don't think it would work for my 4 sider but all you can do is try it but plan for the worse case scenario.

I always think its better to overspec than under ............ I do waffle on but hope you get the gist..

Thanks for the reply. I think its going to be underpowered so I'll start looking for a replacement.
I can't find the specs anywhere online and the dealer isn't much use atm as they're mostly shut down due to covid.

Hi David
I have got the normal sitax and it wants 20m/s or 3600 cubic meters an hour. I think yours will do a bit wider so probably somewhere around the 4000
Hope it helps

I've ordered an iTech twin bag with 5000m³/h flow with a 200mm inlet so plenty and could potentially take a 2nd machine at the same time.
Nice compact machine considering the massive flow rate.
