    Silencer reduced noise my 3 to 4 DBz

    I think the silencer was worth the money. I measured the noise with/without silencer. The Ac Infinity 6” fan is directly connected with duct tape joining the items. A reduced 4” hose is attached and taken to the electronics soldering area on the bench.The exhaust is vented out the window via 6” duct hose. I run the system on “step setting 4” and gRead more about review stating Silencer reduced noise my 3 to 4 DBzet 38 DBz measured from the mouth on the 4” pipe, 12” from mic. Using Apple iPad app to measure with built in iPad mic. Ambient room noise is 25 DBz. I can solder 6” from intake and no fumes escape. I got the 6” fan so I could run it at reduced speed to traduce noise. Summary, worth the money and works with my setup. This is very quiet and in no way bothers me. If the fan/muffler we moved further away it would be near silent.
