SysTech LO-NOISE™ Attenuated Fan Packages

SysTech LO-NOISE™ Attenuated Fan Assemblies are designed to meet demanding noise specifications, Code and client requirements that will attenuate noise while removing heated air from buildings. These custom designed low noise fan units, labeled as LO-NOISE, that reduce noise exiting from buildings that house engines, compressors, fans and other rotating equipment that might have an impact on the surrounding environment. These packages or assemblies will come complete with exhaust or supply fan, an automatic or manual damper, intake or discharge hood, roof curb where required and silencer designed for a specific noise level.  Typical control options include Variable Frequency Drives, temperature sensor or opacity meter.  They are constructed for easy “drop-in” installation with easy access to internal components if maintenance is required.
