Fireye 19-117 Filter Assembly

The Fireye 19-117 Filter Assembly is a critical component for maintaining the precision and longevity of Fireye oxygen probes in high-temperature combustion environments. Designed to protect the zirconium oxide sensor from particulate buildup and fly ash, this replacement filter assembly ensures consistent in-situ oxygen monitoring for industrial boilers and burners. Proper filtration is essential for preventing sensor poisoning and drift, which directly impacts combustion efficiency and fuel-to-air ratio control. The 19-117 is engineered to withstand harsh flue gas conditions, maintaining structural integrity while allowing for optimal gas diffusion. Contractors should verify the housing seal during installation to prevent ambient air infiltration, which can lead to false high O2 readings. This HVACR replacement part is essential for facilities running Fireye burner management systems that require low-maintenance, reliable oxygen sensing for regulatory compliance and operational safety.

• Enhanced Sensor Protection: Shields the oxygen probe from abrasive particulates and combustion byproducts, extending the service life of the sensor head.
• Optimized Combustion Control: Facilitates accurate stack gas analysis, allowing for precise trim adjustments and reduced fuel consumption.
• Durable Construction: Built to withstand the thermal stresses of continuous industrial burner operation without compromising filtration efficiency.
• Direct OEM Fit: Designed specifically for compatibility with Fireye probe housings, ensuring a secure and leak-free installation.

How often should the Fireye 19-117 filter be replaced?
Replacement intervals depend on the fuel type and flue gas particulate load. In heavy oil or coal applications, frequent inspection is required to prevent sensor lag, whereas cleaner-burning natural gas applications may allow for longer intervals.

Can this filter be cleaned and reused?
While some loose debris can be brushed off, the microscopic pores of the filter media eventually become blinded. Replacing the assembly is recommended to ensure accurate O2 trim system performance.

Will a clogged filter affect my burner's safety limits?
A clogged filter typically causes slow response times or "lazy" readings, which can lead to inefficient combustion or nuisance alarms in AEO-optimized combustion sequences.
