The use of the Can-Fil fan silencer reduces fan and air noise dramatically.
There are two sizes available, 500mm & 1000mm high
Both can be fitted withCan-Filter flanges (if required) for different fan and duct sizes.
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.
