Vacuum Cleaners Discussions

I just recently installed a signature central vacuum system,I should have done this 20 years ago,Now were all done buying vacuum cleaners every 2 years.

Has anyone else on the forum gone this route?

Carmine,
240 volt systems are usually two motor systems and are more powerful than 120 volt systems.  A 120 volt unit with comparable power would require #10 electrical wire which is more expensive to run and would also require a 30 amp circuit instead of the 15 or 20 amp circuit the 240 volt system requires.  However, there are 120 volt systems that are still powerful and plug into an ordinary electrical outlet.

Thank you.  I'll keep that in mind.

Hi Guy's ,is this fact or fiction, Do twin motor systems create too much heat between the motors, IF they are set up without the tangential discharge,or horn motors.

I have seen a lot of nutones that use the twin motor perefial dicharge motors, or not positive bypass motors. There seems to be a lot of control board failures because the heat disapation is not set up correctly.

Most all the life of the house warranteed units are single stage ametek/lamb equipped 7.2'' 3 stage blower motors. The brush life is 1200 hours. The warranty stays in effect only when the carbons are changed. I have personally repaired vac-u- flo units,cyclonic model 26's that are over 40 years old.The 334 lamb 2 stage motors,are considered the best central vac motors ever. They run at 110,110.

The nicest set up i've seen lately is the soft start  ignition modules. No instant on 19500 rpm shock starts.

IF you are getting a 2 motor central vac, avoid any with the motors in series.  These will cause overheating and much shorter motor life.  Its mush better to have a 2 motor central vac with the motors in parallel.  I personally have a Riccar (made by Cyclovac) unit with 2 Domel tangential discharge motors in parallel, with each motor having its own exaust.  Its a 240V unit.  As for a 240V motor running cooler, they usually do.  This is because they typically use less amps.  Each motor in my unit uses about 6 amps, the sticker on the unit says it uses 12 amps total.  The 120V version of this motor uses about 9 amps.  The lower amperage means the motor will run cooler.

At the International Builder's Show in Orlando I saw a new unit Vacuflo has.  It has two of the good Lamb Ametek motors in series.  It is really powerful.  I don't think there is an issue with motor life because VacuFlo offers a lifetime warranty on parts.  VacuMaid manufactures a central vacuum system with a Lamb Ametek motor that stops when the carbon brushes get worn down so that you can replace the carbon brushes before the motor burns up.  I think I would stay with a system that has a Lamb Ametek motor.  I'm not really sure about the motors that are made in China or Eastern Europe.  Lamb Ametek has longevity in the central vacuum industry.  I have a dual motor Imperium central vacuum and I use it with a Hide a Hose, which I love.
