Boost Cooling. Double RF Load Power.

Blower Assemblies

Bird® BA Series Blower Assemblies provide forced-air cooling for Bird 8890 Series RF Loads and 8329 Series RF Attenuators. By directing airflow across radiator fins, these assemblies double the power-handling capacity of supported loads—keeping systems stable and safe under increased RF power.

Selection Tip: Use an interlock thermoswitch with your blower-equipped load to enable automatic temperature-based activation.
