Relief dampers are backdraft dampers with an adjustable start-open pressure that allows excess air escape to lower indoor pressure. Barometric relief dampers are used for gravity ventilation and low-velocity systems.
Barometric Relief Damper, Horizontal Mount
Pivoted backdraft damper for low-velocity systems. Horizontal mount allows vertical upflow; flangeless design opens with airflow and closes to prevent reverse flow.
Barometric Relief Damper, Horizontal Mount
Pivoted backdraft damper for low-velocity systems. Horizontal mount for vertical upflow; discharge flange supports install and prevents reverse airflow.
Barometric Relief Damper, Horizontal Mount
Pivoted backdraft damper for low-velocity systems. Horizontal mount for vertical upflow; intake flange simplifies installation and prevents reverse airflow.
Barometric Relief Damper, Vertical Mount
Pivoted backdraft damper for low-velocity systems. Vertical mount supports horizontal airflow; flangeless design prevents reverse flow with gravity-assisted closure.
