Combustion Air Blowers
Controllable blowers with steep pressure/air
flow characteristics curves and high maximum
pressure are required to provide optimal fuel/air
mixture and volume for modern gas or oil-fired
heating boilers that operate in modulating mode,
and also for gas technology in every operating
status and external condition.
Protection class:
Pressure relief:
The motors comply with the requirements for
protection class III. At rated voltages of over 42
V, therefore, a potential separation is provided
for between the voltage supply to the motor and
the interface to the control module and, com-
mensurate with the requirements on greater
insulation, creepage distances and clearances
of 8mm are also provided for. Protection class III
then only applies to the signal plug.
Apertures for pressure relief on request.
Commutation electronics:
Motor electronics integrated in the blower unit,
with start-up current limit and reverse battery
protection using plug coding, locked-rotor pro-
tection and overload protection optional.
See separate drawings for details of interface
requirements.
The RG blowers with brushless DC-motors
have been developed to meet the special
requirements of these appliances. ebm-papst
has played a decisive part in the development of
EC blowers suited to this purpose and can,
today, offer the most extensive range of blowers
for this field of application. The special features
of these blowers can, however, also be used in a
wide range of other applications.
Adaption to the boiler control is required
in specific cases.
The blower complies with protection class I.
Humidity class:
Speed recognition:
The electronics comply with humidity class “E”
according to DIN 40040.
Hall IC signal output (2 pulses per revolution).
RG100: 1 pulse per revolution
The circuit boards are coated with a protective
varnish to safeguard optimal protection in a cor-
rosive environment.
The derivative feedback is galvanically decou-
pled with motors on mains voltage operation.
Housing:
RG and G1G/G3G: Die-cast aluminium
Closed-/Open-loop speed control:
Bearings:
The blower speed can be adjusted over a wide
range using a PWM (pulse width modulation)
signal. The PWM signal is a rectangular signal,
preferably with constant frequency and variable
pulse width. It is activated by an open collector
drive and a pull-up resistor.
Maintenance-free ball bearings covered on both
sides, for the RG100 sintered calotte-sleeve
bearings with a lubricant depot. Calculated ser-
The air tightness required for gas pre-mixing is
achieved by sealing the two casing shells and
the passage hole of the drive shaft. When using
blowers for such applications, special criteria,
testing and approvals have to be asserted with
the customer. Safety tests (gas tightness etc.)
for the complete system have to be carried out
by the customer and are his responsibility.

ration at an ambient temperature of 40°C, hori-
zontal mounting position and typical operating
conditions.
An additional electronic system is available as
an option, to convert an analog voltage signal of
0 – 10 V into the required PWM signal. In addi-
tion, there is another electronic system which
allows to activate two speeds, preset with
potentiometers, via a control input.

Mounting positions 1 – 4 are possible. If the
motor is installed on anti-vibration mounts, the
motor weight is given additional support by an
elastic element. Details of the mounting position
must therefore be provided.
Insulation class F (EN60335-1)
Series G1G/G3G: external-rotor design
Insulation class F (EN60335-1)
The motor is anti-vibration mounted to minimize
structure-born noise; rigid mounting with RG100.
Consultation is indispensable for installation
positions 5 and 6.
Protection type:
