Description
The AERCO 60011-4 Blower Proof Switch Assembly is a genuine OEM replacement safety component designed for use in AERCO boiler and combustion systems. This assembly plays a critical role in the safe operation of your equipment by verifying that the blower or combustion air fan is operating at the correct airflow level before permitting burner ignition. If adequate airflow is not confirmed, the switch prevents the burner from firing — protecting the system and building occupants from unsafe operating conditions.

Application
The 60011-4 Blower Proof Switch Assembly is intended for use in AERCO commercial boiler and water heater systems where combustion air proving is required as part of the burner control sequence.

Why Choose Genuine AERCO Parts?
