Well I've decided to give it another shot. This time measuring my own 75th anniversary edition and the M360 (black) which i borrowed from the shop i work at for testing purposes. The 75th uses a dual stage motor, not as long as the triple crown but it is indeed a dual. The M360 uses the new single stage. Both of them have had their container and seal cleaned and a new genuine cellulose cone installed. I also used the same hose wand and power nozzle for both machines. So how do they stack up? Let's see how they did. But first lets look at a few specs on them. Using a Kill-a-watt meter i was able to see how much wattage each machine used.
The 75th drew about 947 watts on high the M360 drew about 1108 watts on high A waterlift guage was attached directly to the machine bodies to compare waterlift. As can be seen here the 75th did, surprisingly, slightly better. |

I was going to go through and do the measurements again with a medipure filter but decided it was too much hassle so i just took a nozzle reading with it.
With medipure @ nozzle 63.71 Without medipure @ nozzle 68.85

While we have a much higher base power the difference at the nozzle is a mere 8.22 cfm

That's quite a lot of difference in the wand right before the rug head.

...so, how do you measure the airflow for a given machine, and what do you need to do it? |

For accurate airflow measurement Anemometer is needed.

A GM8901 anemometer if you measure in ft/min you multiply that figure by .026099 to get cfm, Another member calculated that out i just use his Figure. I also use the cuff from a baird meter to get a decent seal to the vane, and then for nozzle testing i've built a sealed wooden box to redirect all the flow to one hole for measurement.

Are Airstorm/Patriot vacuum even made anymore? All I can find are tools and bags on line. |

I'd imagine forcing the airflow through a smaller opening than the original probably does reduce it somewhat, however I cannot imagine it's a significant amount. I was getting a reading of about 137 or 138 for the Avalir. Even if the numbers are not fully accurate they still provide a comparison using the same tools, techniques and variables.

It might not affect the results any more than attaching a Baird meter to any opening, since the meter itself has a fixed diameter. Even if it does affect it, it's consistent. Ultimately, you have to have some way to test airflow at the level of the floor nozzle, so I'd think that's as good as any. Are you able to put other uprights and power nozzles onto that box, or is it sized specifically for a Kirby?

I'm not sure if the Patriots are still made, but greatvacs usually has some in stock and sells them at a good price, very similar to the older Tristar models. Mike |
