The use of fan silencers reduces fan and air noise dramatically. All can-fan silencers can be fitted with flanges (if required) to suit different fan and duct combinations.
To assemble, simply position the fan on the carbon filter, making sure the airflow direction is correct (sucking in through the filter and out through the silencer). Then fit the silencer on the fan.
The Can-Fan Silencer 1m suits 250mm-315mm flanges
