Beautiful! Could you please indicate at what air volume and pressure you have been able to achieve the 90% efficiency?

[@andreidulski7199]

beautiful! what type of glue do you use for the PP sheets? Have you managed to calculate any efficiency figures? Have you experienced any problems with dirt getting stuck inside the empty cells?

[@diyvmc4523]

Andrei Dulski I used normal anti-mold silicon glue. The efficiency measured is over 90%. No problems with dust due to the filters in both channels.

Ok, so the stuff in the small siringe is silicon glue? Not the one used at the end to glue the metal sheets...

[@diyvmc4523]

Andrei Dulski exactly, I used the syringe for more control

Good morning. I can ask for the thickness in mm. of polypropylene sheets? Thanks.

3mm
