HELP with fan silencer

ya i just bought a stanley steamer blower for my grow room and the noise a bit too loud, even when its on the lowest setting..any one know how i can change this problem, thanks

Add on some insulated duct.

dynamat.......

Make a DIY Cabon filter. costs 6$

sit on it.

Wrap insulation around it and also use insulated ducting and then there will still be a bit of noise from the moving air.

i put 3/4 inch styrofoam on my walls and cealing and can not hear much standing right out side the door
