Wall Supply Fan Assemblies
“Supplying Ambient Cooling Air is Vital to Ventilating Compressor Stations”
Attenuated supply air fans with bird screen on a compressor station
Wall-mounted supply fans supply ambient outside air to the building to remove heated air produced by compressors, motors, and engines. A typical supply fan assembly includes a weather hood, louver, fan, damper, or diffuser. When noise is an issue a silencer section is installed after the fan. SysTech builds complete wall fan assemblies designed to be inserted as a package. This reduces handling and installation time for the installer.
