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.

Well a vacuum is any closed area that has a pressure less then 1 atmosphere. So, yes a fish tank pump can create a vacuum. And the previous person unintentionally answered your question... the vacuum will likely suck out the majority of small particles in the chamber, hence lowering the ppm of the particles.
About gravity, I think it's safe to say that more particles would fall to the ground in the chamber. In the presence of a lot of wind, a lot of particles are blown off things and go airborne. No wind will allow these particles to fall down to earth. However, you said wind resistance... Its not resistance of the wind, its the wind itself.

Sorry, but the dust particles would likely be sucked out of your vacuum chamber by the pump before they could fall. The pump would probably rupture its diaphragm or burn out trying to pull any significant vacuum.
