The use of inlet and discharge silencers is highly recommended.
Most designs incorporate some means of noise reduction. Here are a few points on
reducing noise:
x
Choose chamber type silencers if rotary blower speed is below 2250 rpm.
x
Choose absorption/chamber combination silencer when operating rotary blower above
2250 rpm.
x
Use large silencer volumes in excess of 15 times
volume flow per revolution to minimize pulsation.
x
Use silencers that attenuate peak frequencies
equivalent to 0.06 x RPM.
x
Discharge silencers must be rated for
temperatures above expected discharge
temperatures during operation.
x
Sound enclosures are required to achieve noise
levels below 85 dba.
x
Sound enclosures must have adequately ventilated
to maintain normal ambient operating temperatures.
10. Operating a Rotary Blower
10.1. Prior to Starting Unit for First Time
Every rotary blower undergoes a mechanical run test at full nameplate pressure prior to
leaving the factory. During the test, key indicators, such as vibration and temperature,
are monitored for unit quality insuring conformity to specifications.
It is expected that the user employs safe working practices, and that all lawful operating
and safety regulations are followed when operating this rotary blower.
