Quietest 8 inch inline duct fan???

anyone know ive been told max fan but not sure also whats are some good filter brands phresh or can?

Wouldnt mind knowing this about 6" fans as well as im currently shopping for one

To be honest fellas i just don't think its possible for either to be quiet. I had a 6" RVK that sounded like a spaceship, I put it in a box and filled it with expanding foam and it still sounded like an airplane.
I'd be up late at night thinking helicopters were surrounding my house, shitting myself.
The bloody thing isoutta commission now, you can have the bugger

Hands down!

They make an 8" but I only own 4 of the 6" 340 cdm and they are the quietest a fan can be especially if hung from a joist using bungee cords!

I use an RVK150A1 rated at 480m3/h.

I grow in a walk in closet and unless I'm in the closet I cannot hear it. However the closet is behind a fake wall that I built.

The closet is directly above my stairway and directly underneath the closet I cannot hear anything.

I used to use an RVK150L1 660m3/h that was mounted in the attic to my roof supports and that fucker could be heard all through the house and outside.

ive been told be monster gardens that the phresh hyper fan is quietest and best fan out right now
