And here are some photos from the actual site since I hit the attachment limit on previous post:

Exterior fresh air intake:

Exhaust silencer:

Interior intake:

Proposed fan place change:

Sorry not sure why some got rotated like that, will try to fix this later.

EDIT: there you go, fixed. It seems to happen for JPG (in capitals) file extension.

All the best for new year,
