If you made a vaccum chamber would it make the small paticles floating around in the air to fall to the ground becaus of no wind resistence; and how much pressure would you need for it to be a vaccum. Would putting a fish tank air pump in the vaccum chamber with the hose attached to a one way valve pumping the air out be powerfull enough to creat a vaccum.

why would the particles fall in a vacuum? you wouldn't use pressure to create a vacuum, and no, your pump from the fish tank is not powerful enough to create a real vacuum

I think that in basic terms any amount of negative pressure is a vacuum and as long as it is strong enough it will be able to draw in the dust particles you mention along with everything else in the air. You should also know that the vaccums that we are able to create are limited and can't be absolute vaccums, that is that you can't keep on sucking away forever and you have to place the matter that you suck in somewhere. Also, the amount of vaccum applied is usually measured in inches of mercury and can be created in an infinite number of ways. Your idea is a basic vaccum cleaner type set up except for you didn't address where you were going to move the dust and air to. You can also create specific vaccums by toying with pressure differentials using liquids and gases, and displacement techniques that may or may not involve the exchange of heat. Good luck and if you're trying to blow your weed exhalation into a device so that your parents won't find out you need a better idea.

If you pump air out of a chamber, you will likely also pump out much of the suspended particles. The remaining will likely fall out more readily because there is less gas to keep them afloat.
A vacuum means less air pressure than ambient; even a slight reduction is a vacuum. As the pressure difference goes up the vacuum is considerred greater.
A fish tank air pump will create a vacuum but not a substatially large one.

vacuum and dust are not the same ..you can have dust under vacuum. Dust is cleared by filters to purify the air. How much vacuum are you requiring...yes any pump can create a negative pressure perfect vacuum is 29 inches of mercury ..

Sorry, however the dirt debris could probably be sucked out of your vacuum chamber by the pump earlier they could fall. The pump could probable rupture its diaphragm or burn out attempting to drag any important vacuum.

It lowers the ppm of dust because dust is pumped out with air!
