We have got some really good news for our customers. As of Friday, we now feature not one, but two central vacuum power units with the latest 8.4" Lamb Ametek motor. This motor is a powerhouse and now our customers can purchase a filtered or bagged unit with this motor.
Recently we became the US distributors for the RhinoVac. The RhinoVac 511R-XLS is a "beast" with 110" of sealed suction and 166 cfm. This filtered unit has a teflon coated inverted bag. The RhinoVac is also priced lower than comparable filtered units. Maybe you are one of those customers that prefers a paper bag unit, well, we have good news for you...
As of Friday, Central Vacuum Stores now offers their popular Imperium central vacuum systems with disposable bags, and the brand new Imperium CV800 not only offers a disposable bag, but the same powerful 8.4" Lamb motor found in the RhinoVac. (110" sealed suction and 166cfm) You'll notice our new bagged Imperiums are emerald green. That's how you'll be able to differentiate them from our other Imperium units (our cyclonic, commercial, and filtered Imperium units will still be our signature ruby red). This unit uses the Maxflo Hepa Filter Bag for superior filtration and dust containment.
In describing these units I only mentioned sealed suction and cfm in the specs for these machines. As I've mentioned in previous blogs, AirWatts is a strange rating. First, it's a formula, and you can find it all over the web (I even think we have the formula somewhere on our website). However, if you plug in the numbers, the formula doesn't work. That's because AirWatts comes from the cfm and sealed suction numbers taken in specific test environments. And it's just kind of dicey. You can find three units, all with identical specs and the same motor, yet all have different AirWatts.
The ASTM says Maximum Air Watts is the way to measure how well a vacuum system will clean. Unfortunately, the ASTM doesn't give us the specs, the manufacturers do and they all test in their own way...some at the motor, some at a 2" opening, and some without the dirt can attached. MD Manufacturing, a leader in the central vacuum industry, says that the statistics for maximum air watts comes from the manufacturer and the numbers may not be reliable because they aren't tested under conditions commonly used. MD recommends you know the opening size of the attachment most often used and then find the vacuum's air watts at that exact opening size...
All that to say, if you are comparing units and their specs (cfm, inches of water lift, and airwatts) are close, then you are comparing units that for all practical purposes are equal in power.
