Description
The Kromschroder 84447820 Pressure Switch is a gas and air monitoring control tool used to detect, and verify safe pressure conditions in a combustion unit in the HVAC system. It operates by responding to changes in differential pressure, and switching an electrical circuit when set pressure thresholds are reached, helping ensure safe ignition, and stable burner operation. It is typically used in gas-fired heating appliances, boilers and burner assemblies within equipment. It supports reliable equipment safety under typical operating conditions by preventing operation during insufficient airflow or abnormal pressure states.
