[Gasification] blower suggestions?

Wed Aug 8 13:34:58 EDT 2007

here's a good summary of common central vac motors:
http://www.thinkvacuums.com/allcomparemid.htm

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.

5.7 vs 7.2 Diameter - What's 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 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.
