DO NOT EXCEED THESE LIMITS
NOTICE
Blower speed, line losses, elevation, and increased inlet temperatures will affect the maximum
operating limitations. The minimum RPM for the blowers is based on lubrication only. The
blowers may only be operated down to the minimum RPM, when the temperature rise and
discharge temperature are below the maximum limitations as shown.
FIGURE 4-1
– MAXIMUM / MINIMUM OPERATING LIMITATIONS
(1) Resonance phenomena in the plant are possible when the rotation speed is close to the minimum.
(2) 320°F for blowers /R-V
4.1 Flow adjustment
Change transmission ratio
Change frequency of the motor
Use a two-speed motor
Discharge excess flow and silence it
Do not use relief valve to discharge excess flow
Do not recirculate flow to blower inlet.
Do not adjust flow by throttling inlet or outlet pipe
4.2 Noise level
Noise level of the blower is indicated at page 4 as Sound Pressure Level according to ISO 3476 at 1m
distance from the blower and in free air (to/- 2dB(A))
For high compression ratio and for high speed of rotation noise level of blower can be higher than 85
dB(A)
