Insulation Vac


My house, so as usual I have a stupid question because it's not my usual area of experience:

I want to move about 400sf of L77 50 feet or so from a living room area to insulate a garage, then do some remodel wiring in the attic before re-insulating the living room.

That stuff is so light and fluffy, can I just set up a duct fan in some flex duct, or do I need to hire the insulation vacuum guys.

Yes I could just wade around but I'm doing enough work this way seems easier.

Re: Insulation Vac


I doubt the fan will have enough pull, even for OC fiberglass. If it were even possible, the fiberglass would eat your blades within minutes. If you cannot shovel it with a feed shovel, then consider renting a vacuum at Sun Rentals (if there is one by you).

Re: Insulation Vac


It would cost, minimally, $1.50 a square foot to hire out.

The 1hp dust collector would not have enough cfm. You would, minimally need a 3hp electric hp. The smallest gas vacuums are 6hp.

Sounds like I need the real machine. I asked the insulation contractor about it once and he would give me a better price because it's new (no debris) and not getting bagged, just moved across the attic.

Re: Insulation Vac


I just sucked the cellulose out of the walls in my house. Used a 1 1/2hp dust collector.

Saved it for the shop attic.

Re: Insulation Vac


The insulation vacs are crazy. I have seen/heard where guys sucked up a framing nail that was in the attic and it would go right through the hose nearer the vacuum and actually stuck in one of the guys.
