REASONS FOR
CHOOSING NR three- lobes blower: |
|
|
|
|
|
|
|
|
|
|
|
|
|
 |
Low
energy consumption
Three- lobes design reduces the pressure on the rotor from back
flow, also reduces energy consumption.

|
|
|
|
|
|
Low
noise
The blower reduced the pressure pulses, major noise source.
|
|
|
|
|
|
|
|
|
Durable
The bearing lasts longer due to less vibration of the lobes.
