This system is just a central vac that's running in reverse. You can find a central vac on craigslist for cheap.
It looks like a central vac however central vacs are designed with cyclonic action to trap dirt so reversing the unit would not be the same.
Maybe it could be done with modifications. Removing the filters and maybe some other changes to the inside.
It maybe worth a try? I certainly would luv to see a YouTube video where someone did that and showed it working
The one in the diagram on the left is in our house.

Description
The two main types of central vacuum systems are cyclonic and filtered. According to CentralVacuum.com, the type of system plays a major role in the efficiency and longevity of your central vacuum unit. Whenever you have an appliance (like a vacuum) that collects dirt, some sort of filtration system is needed clean out the debris. What makes a system good is its ability to minimize the debris, while maximizing airflow for vacuum power. The build-up of dirt in the bag or filter over time can be a contributing factor to the eventual breakdown of the machine. You will want to clean the system according to the manufacturer's instructions.
Filtered systems can use a variety of filters such as screen, cloth, foam or paper to clean the air taken in by the vacuum. In any filtered system, filters need to be cleaned and replaced. A cyclonic system uses centrifugal, tornado-like force and gravity to separate the impurities from the air being taken in by the vacuum, and typically deposits the dirt into a canister (although some systems may use a bag).
For the power unit, there are two main things you should consider:
How much power do you need?
Do you want a bag or canister unit?
According to CentralVacuum.com, homes of less than 5,000 square feet (465 square meters) require a power unit of 20 amps or less. If you have a larger home, you'll need a more powerful unit.
The other decision you need to make is whether you would like a bag or canister unit. When you go to empty the dirt receptacle, it will be either a plastic canister or a replaceable bag. Both systems are efficient -- it is simply a personal decision. Would you rather dump and clean the canister or toss a replaceable bag into the garbage? Either way, chances are you will be disposing of debris a lot less often than with traditional portable vacuums.
