Bard 8301-057 - Adjustable Filter Pressure Switch

The Bard 8301-057 is an OEM adjustable filter pressure or airflow pressure switch used in select Bard wall mount and wall mounted Fusion-TEC units to monitor pressure drop across the air filter and signal the control system when airflow is restricted. If your unit is tripping dirty filter alarms, cycling on safeties, or not maintaining proper airflow after a filter change, a weak or out-of-calibration switch can be the cause. This factory-correct switch is designed to match Bard wiring and mounting requirements for dependable filter status sensing and proper unit operation, and adjustment allows the trip point to be set to the equipment specification during service.
