Hi Jason Pont,

Thank you a lot for the help.
We will make below solution, because we need separate duct for fan 37kW. When we will install it, I will inform you whether it work fine

One ore time thank you a lot

Hi Jason,

Thank you very much for help. Then we will skip the proposition of installing non return valves.

What do you think if we will move the fan up like at the drawing. 
Does that make sense? Will I then suck air from small channels

Hello,

I need help with ventilation. I will explain briefly wht is the issue.

I have manifold (kolektor) to which a lot of small pipe connections are made (sides). Through these pipes fan 55kW is sucking the air and odour from some factory. This installation was working fine until new fan was connected at the end of the line. Now when this fan 37kW is working it is blowing the air to small channels. Fan 55kW is not able to prevent the air come to small pipes. 

I have think over this issue, and I found that solution (page2) that I will install 1 way valves (DN300 - zawór zwrotny). Do you think that this solution will work? The aim is to avoid backpressure in the side pipes. And at the same time it is necessary to suck the air from these pipes.

Then at 3 page I shown 1 side pipe which is connected to screw conveyor sucking the odour with air. It is necessary to regulate the air force sucking from this screw, so I found out that we can build new inlet of air just in case if the sucking force will be too big with some regulation valve.

Please tell me whether it will work? Thank you for help. Tomasz
