Unfortunately, the solution you proposed is not possible.
There is not enough space available inside the connecting pipeline between fan and filter to allow proper airflow.
During the project’s initial phase, different positioning solutions had been evaluated. The solution we proposed - represented in the current lay-out – appears to be the most suitable one.
Thank you very much for the photos that you sent concerning foundations works’ progress and I take the occasion to suggest you pay particular attention to the foundations of Pendular mill and in process filter fan’s area. The two foundations must be aligned, flattened and horizontal as much as possible.
For any further assistance or clarification, do not hesitate to contact me.
