Exhaustion Vacuum Outdoors...

Barb,

For possibly moldy or allergenic dust, you're better off standing or hanging

the shop vacuum just outside a window and using all the extra hose indoors

on the " vacuum " side. If you have a short vacuum hose and a long

pressurized exhaust hose going across the room and out the window, the shop

vac is more likely to leak to the insude. There is usually some bypass

around the motor anyway.

The difference is in the hose you buy. You could use any light gauge dryer

hose if it is pressurized but if you use the extension on the vacuum side

(as I am suggesting) the extension hose must be stiff enough to keep its

shape and not be crushed by the atmospheric air pressure; cheap dryer hose

would not work. Shop vac extension hose is expensive. Maybe there is cheap,

black flexible three-inch drainage hose (not the perforated type used). Two

inch hose would be better (easier to adapt) but more expensive.

I DO have a shop vac that has never come out of the box I could use.

Is pool hose like a garden hose ??

The radiator is REALLY **FULL** of dust and dirt. When it is heating

up apartment, it is cooking this dust and dirt so creating air

pollution that way...maybe not viable mold spores, but definately lots

of stuff, looks like it is a long time accumulation.

Geez, I'm going around cleaning up all these heating and cooling

systems at places I'm just staying temporarily. They should pay me to

stay awhile at their place. I get all the deep down dirt out. If I

made a job out of this, cleaning air and heating systems, it would be

kind of like modern day chimney sweep.
