Central Vacuum Systems - Suggestions

Preface:  A good Central Vacuum System is an asset to a home, office or store.  There are a number of reasons for this:

• A good Central Vacuum System (CVS) has a much larger motor - or, in instances, motors - than a residential "pull-around" canister vacuum or upright vacuum
  • This larger motor - or, motors - will provide more cleaning power than a standard residential vacuum.  As a comparison:
    • A top quality residential canister vacuum will provide between 80" & 100" of waterlift; and, around 100 cfm
    • A good quality residential upright will normally provide between 60" & 80" of waterlift; and as much as 90 cfm
    • A good quality CVS will provide between 125" to 160" of waterlift; and                                                                          between 110 cfm to 180 cfm
• A good quality CVS will have a much larger dirt capacity
  • The increased dirt container size reduces emptying frequencies
  • The increased size allows the vacuum to "breathe" better - helping it to produce and then maintain increased cleaning power
• A good quality CVS not only allows for the pollutants being cleaned from the rug, upholstery, drapes, floors, etc. in the house to be removed to a separate location, it will filter these same pollutants out of the exhaust air down to the microscopic particle size of .3 microns
  • Most canister or upright vacuums are spewing millions of these same microscopic pollutants per minute back into the room in which the vacuum is being used
    • We are experiencing an unprecedented epidemic of allergies and asthma problems (internationally) - it is only common sense to successfully remove allergens from the indoor environment; not, to increase the airborne pollutants!
  • This type of critical filtration also serves to keep the motor(s) "whistle" clean
    • A clean motor runs with less vibration and heat and will, therefore, last longer
• It is fairly effortless to move around the house or office with a 30-foot to 35-foot hose
  • Most pull-around canister vacuums, etc. use hose of 5-ft to 6.5-ft. in length
  • It is suggested to install a soft "hose sock" on the outside of a CVS hose to protect molding & furniture

Our Suggestions:

Central Vacuum System:  We think that DuoVac makes one of the finest lines of Central Vacuums in the industry

• DuoVac has been manufacturing commercial-grade CVS for over 30 years
• DuoVac models are extensively used throughout North America in commercial applications such as mall stores (i.e., the Gap, etc.)
• A machine used successfully in demanding commercial applications will work wonderfully in regular residential use
• As explained in our webpage on Central Vacuum System Information a good CVS always incorporates two, important design features:
  1. Cyclonic entry of dirt to maintain high airflow
     • High airflow (along with good suction - i.e., waterlift) is critical to effective vacuuming
  2. Effective filtration to ensure clean exhaust air
     • Clean exhaust controls emissions of LDP (Lung Damaging Particles)
     • Clean exhaust allows the motor(s) to last longer
• Our most popular CVS by far is the DuoVac model 1530
  • 145" waterlift
  • 102 cfm airflow
  • Cyclonic action
  • 7.5 gal size
  • DuoFib filtration 95% efficiency @ .1 micron (no venting needed)
  • 7.2 inch 3-stage Lamb 117500-13 motor 14.4 amp

Hose:  We think that, for those who need a motorized brush for carpet use, a 35-foot electrified Plastiflex hose with Dual-Voltage switch is the easiest, optimal hose to use

• Lightweight & durable
• 35-foot hose offers a bit more leeway & flexibility in use than a standard 30-foot hose
• Full 360-degree swivel hose end at user end
• Orthopedically formed grip for hand comfort and ease-of-use
• Dual voltage, thumb-operated switch on hose end allows user to instantly switch either main vacuum off or on or to switch power nozzle off or on
  • No need to go back to the wall outlet to remove hose end to turn main vacuum off
  • Switching off power nozzle enables quick cleaning of adjacent bare floor areas when initially cleaning carpets/rugs
• If a power nozzle is not used on the CVS because there is such little area covered with carpet, a non-electrified, SVUF wire-reinforced hose is suggested
  • Either 1 3/8 inch or 1 1/4 inch size in a 35-foot length
    • 1 3/8 inch recommended as it carries the air better for more efficiency

Motorized Power Nozzle:  Unequivocably we recommend the Lindhaus PB14 power nozzle

• 5,000 rpm, ball-bearing brush
  • High brush speed for fast cleaning
  • Ball bearing design for no vibration and long brush life - probably 20 years!
• Large, central dirt intake
  • Improves cleaning performance when the dirt intake is centralized
  • Convergent brush design sweeps dirt from either end of nozzle into the central intake
  • Least efficient design is to locate intake at extreme end of revolving brush
• Precise sensor system
  • Sensor system constantly monitors brush resistance and shuts off revolving brush if it jams or becomes unduly impeded
    • Such a system protects the belt from breaking
      • Belt has an initial warranty against breakage for 3 years!
    • Protects a carpet fringe, etc. from being yanked out of the carpet
    • Protects the brush and motor from undue stress

Cleaning Accessories:  We suggest a good-quality set of accessories

• Miele-style combo rug/floor nozzle
• 12" horsehair-bristle bare floor brush
• Full 360-swivel dust brush to facilitate dusting in difficult-to-reach areas
• Set of steel, button-lock wands
• Crevice tool
• Upholstery nozzle with lint picker
• Plastic hose hanger
• Optional hose-sock to be installed on hose to protect molding & furniture from being abraded by action of hose being pulled around corners, etc.
