Finally got my mitsubishi Lenta silent 25 installed

After some delay I've finally now started installing the ventilation system.
I ended up with two duct fans K125 EC (Ø125mm / 490 m3/h) connected to fiber glass inulated flexible ducts. One for fresh air and one for exhaust.
The fresh air and the exhaust air will be connected to their own flexible ac silencer. The fresh air ducts is connected with air filter and heater for cold days.
I will control the air-condition from my home made control unit (made from raspberry pie with a touch screen mounted in the wall inside the room). This is also where all the lighting is controlled and some other cool features. I will post a separate topic on the raspberry pie controller when its finished (only lighting control is done as of today).

Updates will be posted soon.

All comments / suggestions will be highly appreciated.

Im currently in the process of ordering the wall fabric. I have currently ordered some samples of FR701. Will this be the right way to go?.. And also is there anyone that has any experience with the FR701 mounting frames for walls, or is it easier and cheeper just to go with building my own frames and stretching the fabric over the frame before mounting it to the walls as explained by john.

Also I'm wondering if I should use the fabric directly over the isolation (sins its inside out design). Or should I have something in-between the fabric and the isolation. Im afraid the the isloation will come through the fabric over time.

If anyone has comments or suggestions on the latest posts dont hesitate to comment. It will be highly appreciated

I'm afraid I can't be of any help to you with your questions but keep up the good work. Really like your silencers and wonder where you got the duct liner from. What is the brand?

Thanks rain. I got the duct liner from a local ventilation store. I don't remember the brand name of it. But I will ask them next time I'm at the store and let you know.

Started with my small ventilation system. Remains finishing the exhaust outlet and building the inspection hatch. Electrical has been pulled but will be connected along with the rest of the electrical in the room when the time comes.

Outlet air finished. Started on closing the ceiling.

Mounted first ceiling panels

Awesome, have you made some progress lately? I'd love to see some more pics.

New update. Finished mounting the ceiling panel. Started on the drum riser ("drum riser" method, that both Glenn and Rod suggest).
