Building outdoor house vac system

[racerboy832]

I have a very small home, Only one bedroom and 6 rooms total. I also have 2)125lb dogs and a hot air wood furnace. My house gets so dusty and full of fur i'm at my wits end. We vaccum all the time but the filters keep getting all plugged up. My folks have a central vac which is good but has a filter. I am looking to make a central vac system that has no filter and just blows all the crude out the back of the house. I guess it would be kinda like a duct collector setup that exhausts outside. Anyone have any ideas?

We have a Giant Schnauzer and Black Russian Terrier .... they don't shed.

So other than changing dog breeds I don't have a solution. Never heard of the type system you describe.

Seems any vacuum system would require a filter to protect the vacuum / suction source.

Racerboy, I have a vacuum system geared for a wood working shop, somewhat different but the same principles.

Understand the Hp ratings, lots of BS. A 120 volt circuit at 15 amps can only deliver 1800 watts. One Hp = 745 watts.
1800w/ 745 = 2.4 hp that may be delivered, at 240 volts, it is 4.8 hp. Circuits are fused to match the wire gauge to keep it from overheating, 15, 20, 25 amps and if the current draw is more the breaker will open. The current draw is de-rated for continuous use, by 80% of max. Therefore 15 x .8 = 12 amps or 2.4 hp x .8 = 1.92 hp.

Manufactures hype the hp by stating the peak hp. For a brief instant when the switch is flipped the motor is not turning and the in-rush current is maximum, may be 30 or 40 amps and that is what they use to come up with peak hp.

Mounting the unit to keep the motor sound reasonable, usually on the outside wall of the garage.
All my duct work is 4 and 6 inch mettle, air and sawdust moving through the duct work will build a sizable static electric charge that may explode the dust in the system, a very big BOOM. For my system, the dust collected passes a giant Cyclone filter that empties in to a 55 gal drum, then on to a 1 micron filter.

You can not use PVC from home-D, you need a conductive duct for safety.

Here are a few sites.

I have a blower that the motor is mounted outside the blower. It is for sucking welding exhaust. I use it all the time when I cut a concrete floor or other dusty jobs. I run a pipe inside and and let her blow outside. This type blower would work in your application.

not true. All central vac systems use plastic (pvc or otherwise) Shop systems can also use plastic. The key is including a wire (or other prefabed connection) that is designed to "collect" the static buildup.

as for suggestions for you issue. a small portable dust collector will provide a fan unit http://www.harborfreight.com/1-hp-mini-dust-collector-94029.html use dryer vent for duct work? cheep and easy to work with. Transition to standard central vac style "plugs" for the wand hookup around the house.

remember that useing a system that exhausts to the outside will generate a negative pressure inside the house so provide a source of fresh air to replenish.

I would rather error on the side of safety and use the conductive duct from the manufacture.

We have central vacuum with cyclone. There is no filter but prety large container (bucket) for the dust. It takes a month or two to fill.

All i'm looking for is a fast way of getting all the dirt, dust and pile of dog hair out of my house. The dogs get brushed out all the time but I feel like i'm living in a dust bowl. We've tried several vaccumms but the filters seem to clogg up quick. I figured if I could wire up a blower motor and use the inlet to suck up the stuff and the exhaust to blow it out of the house then I wouldn't have to deal with it again buy constantly cleaning filters.

You sure about that ?, none of the links you posted says anything about it and one even says it's just like regular water pipe but thinner walled.

Would it be possible to post a link to something about this ?

Here's a link I found that says it's false.
