When using such silencers, the airflow is reduced a lot and the Miner will get hoter - I would recommend to test this before using. Best way if no extra room is available is to put it in a box with with 2 hoses for air input and output.
Hmm, where could I buy such a box, plus what do you mean by 2 hoses for air input and output? I'm in a small room and never done that before? Like would the silencer reduce it from 75 db to maybe 50?
