I've been wanting to try this out for a while. since I have two Oreck Buster B's I thought it would be interesting to hook them into a parallel setup and see how it differed from a series setup
Unfortunately things did not go as planned! The first time I tried a parallel test the units were clearly not sealed The series test resulted in leakage from the body of the 1st unit. I felt they weren't working together as well as they should have been. All I did was connect the hose of the 2nd unit to the exhaust port of the first unit. It was after testing both those I decided I should have a control setup so then I ran the tests on a single buster B with the central vac hose. I was surprised that it has as much airflow as it had at the end of such a long hose. Then I spent time re-setting the parallel setup trying to get a better seal and the back pressure created when the hose was attached cause the bucket to begin collapsing. When I tried to take a sealed suction test the bucket caved in and broke seals. Since i'm feeling lazy here's the CFM number Parallel initial: 50.87 CFM Series: (estimated 2200) 57.42 CFM Single Unit: 53.95 CFM Parallel (Bucket) 131.02 CFM Parallel final: 75.5 CFM Are there better ways to test this? Certainly but the cost of it would be much higher and i'm not curious enough to spend the money. |
