Goomer,
Excellent questions, thank you.
The
Galaxy 2000CX-HR (available in 17 gallon as a 2700CX-HR) has a set of standard performance three stage vacuums. These vacuums offer plenty of power with a conservative amp draw.
We offer several
Galaxy sub-models with configurations designed to fit the unique needs of different operators.
We do have a more powerful and specialized version of the CX-HR available which has the same amp draw as your M5. The model I refer to is the 2000FX-HR (available in 17 gal as the 2700FX-HR). That unit has the same pump as the CX-HR but offers high performance three stage vacuums. This then requires an additional cord to power the machine. That makes two cords for the machine and one cord for the heater. Each cord requires it's own 15 amp circuit.
It's a great unit and it's very popular but we understand that not everyone has that much power available to them.
As far as what motors we use? We use Ametek and Electro motor in different applications and have taken advantage of the advancing technologies and increased performance both companies have offered over the years.
Because these particular units are run in series, we designate the water lift as the primary, and more accurate, unit of measure. Had they been run in parallel, we would have designated the CFM as the primary unit of measure. I will try to get the Air watt measurement of two motors when I return from the holiday. Air watts should give you a better idea of the performance a motor offers because it factors both CFM and water lift at the working end of a hose.
Thanks again for the great questions.
Hope you all had a great Holiday!
