Something Wong with Extractor?

I have the following extraction set up.

However it feels like I can blow with more force than this fan.

What's wrong? :investigating

EDIT: It's wired to the fast speed.

That extraction fan essentially almost equals the same CFM of your carbon filter, which is why you don't feel much suction. So there is nothing wrong, remember you won't feel this insane suction near the filter, I am run an 8inch fan on a 6inch filter and I don't even feel any movement. However when I close everything I can immediately see negative pressure.

I had that same fan. 

 

I upgraded to the 125mm version which is much bigger and works much much better than the 100mm and also runs quieter. 

I only went for the 125mm as my filter came with 100mm / 125mm flanges. 

 

My lesson learnt just start with a 150mm and be done with it
