Bard 8301-104BX - Adjustable Filter Switch
The Bard 8301-104BX filter switch with adjustable setpoint is an OEM airflow proving device used to monitor filter condition in compatible Bard wall mount HVAC units and related Bard air handlers. Installed in the unit’s air stream, it senses pressure or airflow changes as the filter loads up and then signals the control circuit for a dirty filter indication or protective control action, depending on the equipment configuration. Using the correct Bard 8301-104BX replacement helps ensure proper airflow monitoring, reduces nuisance service calls caused by incorrect aftermarket switch ranges, and supports reliable system operation when filters begin to restrict airflow.

What does the "BX" suffix mean?
Bard uses suffixes like "BX" to manage parts internally. These do not change the physical form or function of the part.
A part number ending in "BX" simply means it is packaged in a box for shipping, rather than for internal assembly use.
Example: 8406-142BX is physically identical to 8406-142.
