The most important component in any central vacuum system is
the motor. There are four major suppliers to the central
vacuum industry, Ametek Lamb Electric, the German made Domel,
GS Motors and most recently the China made motor. These
companies make several different motors which a central
vacuum manufacturer can utilize. Some of these motors differ
dramatically in cost, performance and reliability. When
comparison shopping also look at the motor warranty. Simply
put, the longer the warranty the more confident the
manufacture is in their product. |

Europe's
Largest Motor Manufacturer Selects America's Largest Parts
Supplier as Exclusive U.S. Distributor |
 VCP
International is proud to announce that it has won the
rights to be Domel's soul source for distribution in the
United States. Ironically both companies started in 1946,
VCP in Dallas, TX, and Domel in Zelezniki, Slovenia. Both
also had broader focuses and have since specialized in their
niches. VCP started as a wholesaler for all small appliance
parts, concentrating strictly on vacuum cleaners beginning
in 1965. Domel started producing office equipment developing
its first motor in 1953. Domel now manufactures vacuum
cleaner motors, universal commentator motors, EC motors, DC
motors, ventilators and asynchronous and synchronous motors.

VCP Owner and CEO Don Russell said, "We have been talking to
Domel for about a year and a half, both companies doing
their inquires and us doing our market research. We then
came to the conclusion that there was a real opportunity for
a quality motor manufacturer such as Domel to do tremendous
business in the U.S. and Domel thought VCP was the one to do
it.
Russell continued, stating, "After a team of VCP employees
went to visit Domel's factories in Slovenia this spring, we
then knew what we had heard was true, Domel's quality does
blow away the competition."
By the year 2009 more than half of the central vacuum
industry will be using the Domel motor as more companies
have started to recognize the quality and longevity these
motors provide.
Domel has over 60 engineers designing motors. This is more
than five times the main competition. Domel Inc. President
and CEO Peter Korosec, said "We are very excited to bring
our high European quality and longer life motors to the
U.S., and especially working with a quality company like VCP.
Our support team is looking forward to helping VCP service
the U.S. market.

5.7 vs 7.2
Diameter - Whats Better? |
Typically
95% of most central vacuum manufacturers now a days use the reliable
5.7 two stage hi-efficiency (German made) Domel or Ametek Lamb
motor. These motors usually spin an average of 21,000 RPM. Among manufacturers who use the 5.7" impeller series motor
in their most popular models are Drainvac, Dust Care,
PowerStar, WalVac, Honeywell, AirVac, Beam®, Electrolux®, Eureka,
Modern Day Hoover, and Smart Vac etc.
Drainvac, Dust Care and
soon Beam®
use the highest
quality German made Domel double ball bearing motor, that same
motors used in
Miele vacuums, the most powerful vacuums in
the world. The Domel motor is now also featured in ProTeam
Commercial Backpack vacuums, the industries best backpacks,
to insure the longevity and quality their known for.
The German Domel Premier Line of motors utilizes all steel construction,
double ball bearings, no-load fan, and have proven superior
to all other Ametek Lamb motors under controlled testing.
Simply put these motors are the best motors available for central vacuum applications.

* Average Life of a 5.7 Motor
- 18 to 22 Years or More. (High Efficiency)
Ametek Lamb also makes a 7.2 diameter motor, called
"Premier" (Part#115334) their most durable motor ever, which
is being used in most all cyclonic motors. These
motors will move air (CFM) at slower speeds (RPM), thus
extends motor brush life (1,200 hours) and bearing life.
The lower speed creates a
twirling effect or tornado inside the canister called the "cyclonic
configuration" effect, however
this lowers the power
(air watts) as well as
the CFMs and water lift which will also lower your suction. This
does not provide more power, but in actuality lessens it.
* Average Life of a 7.2 Motor - 18 to 22 Years or More.
Impeller Diameter
This is directly related to the volume of air (CFM) a motor
is capable of moving. Many manufacturers use the (America
made) Ametek Lamb & (German
made) Domel motors which have a 5.7" impeller in their most
popular models. Because these motors are universal motors,
and require motor brushes, impeller diameter also affects
motor brush life. Because of the small diameter of the
impeller, RPM is increased to allow the impeller to move at
least 100 CFM. Carbon brushes should be replaced every 800
hours on a 5.7 motor and 1200 hours on a 7.2 motor with
normal household use. Takes only minutes to change and
extends the life of the motor adding years of trouble free
performance.

The Higher The
Air Watts... The Better The Pick Up!
 Airwatts
is a combination of water lift (suction) and CFM (airflow).
This is the truest measure of cleaning power. 99% of all
central vacuum manufactures measure the power of their units
by Airwatts. Maximum Airwatts is recognized by the American
Society of Testing and Materials (ASTM) as the best way to
measure the actual cleaning power of a central vacuum
system. Other misleading terms such as Airflow, CFM's
and Waterlift are not a true measurement of power, but
rather part of an equation that equals Airwatts.
Airwatts = CFM's x
Waterlift divided by 8.5

CFM's x
Waterlift divided by 8.5 = Airwatts |

u
 This
measures the "volume" of air the motor is capable of moving
and works in tandem with "Suction". Airflow can be a bit confusing however,
since performance measurements are taken from the motor and
do not factor any resistance found in a typical central vacuum
system. Filtration, piping, hoses and accessories all
restrict and reduce the amount of actual Airflow a system
has. While Airflow is important to system performance,
Suction or the "pulling of air" maintains the Airflow
velocity necessary to sweep dirt and debris away at the hose
end where vacuuming takes place.
CFM is NOT a true measure of suction, however it
is a form of measurement and part of the equation when
measuring Air Watts. This is a misleading measurement
of suction power. Please note certain companies will lower
this number in order to inflate
the waterlift. This is done to influence a consumer by making the suction
power appear stronger - Wrong!

 This
measures the suction strength of a central vacuum motor.
Essentially, it tells how much "pull" or "lift" power the
motor has. This measurement is always taken at its maximum
value, the 0" inch orifice (sealed vacuum) where suction
is at it's greatest. Since this measurement is taken from
the 0" orifice, it is very misleading. This measurement does
not take into account piping, hoses or accessories etc.,
thus giving a false measurement of power. Often referred to as Inches or Waterlift
or Vacuum, Suction is vital to overall system performance
since it is the "pull power" that maintains Airflow though
the complex network of vacuum pipe, hose and accessories.
While Airflow is necessary for a vacuum cleaner to work,
suction creates the lift and velocity of air which sweeps
dirt away.
Waterlift is NOT a true measure of suction, however it
is a form of measurement and part of the equation when
measuring Air Watts. This is the most misleading measurement
of suction power. Please note certain companies will inflate
this number to influence a consumer
by making the suction power appear stronger - Wrong!
