This system is based upon a vacuum cleaner. I am using a vacuum that goes by the trade name Shop-Vac. They are well known for their tremendous reliability on construction sites and other rough applications. I chose this vacuum because I assumed it would be up to the task of extended run times under medium to high load.
Here are a couple of pictures of the completed system:

This system has gone through three phases. It all started with my original idea to use a central vacuum. Unfortunately this did not work out so well. The vacuum was extremely loud. I purchased the vacuum second hand and it ended up failing. The shop owner at Parkdale Vacuum exchanged the vacuum for my current detachable hose. He was very accommodating and this hose plays an integral part in my system.
The second phase was replacing the vacuum with a Shop-Vac. This new vacuum was quieter and provided ample suction. At this point I switched on the vacuum by running outside and switching it on. It was rather inconvenient but it served my needs for the small amount of soldering I was doing.
The final phase was adding in the remote control switch. I have taken pictures of the electronics that I used to complete this portion of the project. The control system is based upon a relay controlled outlet. I used two outdoor receptacle boxes, a GFCI outlet, a toggle switch, a relay and a small 6V transformer.

The relay and GFCI just barely fit into the dual ganged receptacle box! You can see that I have added the control wire in the picture below.

I have sealed the entire box up using a Decora wall plate. I added a very nice industrial grade male plug and tightened the grommet that enters the receptacle box.

It is important to note that a system of this nature could pose a safety risk if extracting flammable fumes. I only use this while soldering and hot gluing to keep the odor and toxins out of the house.
