Duct Filter","description":"\u003cp\u003eThe \u003cstrong\u003eSystem Sensor F36-05-00 Exhaust Duct Filter\u003c\/strong\u003e is the critical OEM replacement component required for maintaining the \u003cstrong\u003eDH400 series duct smoke detectors\u003c\/strong\u003e. As any veteran tech knows, airborne particulate and high-velocity debris in commercial HVACR trunk lines are the primary drivers of nuisance alarms and sensor fouling. This factory-spec exhaust filter is engineered to protect the sensing chamber's integrity by screening contaminants before they compromise the \u003cstrong\u003ephotoelectric sensor\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cp\u003eRigidly constructed to meet \u003cstrong\u003eNFPA 72 duct smoke detector maintenance\u003c\/strong\u003e standards, the F36-05-00 ensures that sampling air remains clean for accurate obscuration readings. When performing quarterly inspections or solving intermittent trouble signals on a high-static system, replacing this \u003cstrong\u003egenuine System Sensor part\u003c\/strong\u003e is non-negotiable for system uptime and compliance. This filter is a direct-fit solution that requires no modifications to the housing, ensuring your fire safety loop remains at peak sensitivity without the risk of \u003cstrong\u003efalse smoke alarms\u003c\/strong\u003e caused by clogged intake paths.\u003c\/p\u003e\n\n\u003cstrong\u003eKey Benefits for the Contractor\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Compatibility:\u003c\/strong\u003e Specifically calibrated for the \u003cstrong\u003eSystem Sensor DH400\u003c\/strong\u003e housing for precise airflow management.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContaminant Suppression:\u003c\/strong\u003e Effectively traps dust and debris to prevent sensing chamber contamination and premature \u003cstrong\u003esmoke detector failure\u003c\/strong\u003e.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimized Airflow:\u003c\/strong\u003e Maintains the required differential pressure within the sampling tubes to ensure consistent detection.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustrial Durability:\u003c\/strong\u003e Built with high-grade materials to withstand the temperature fluctuations and moisture levels found in \u003cstrong\u003eRTU and AHU ductwork\u003c\/strong\u003e.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cstrong\u003eCommon Questions \u0026amp; Technical Information\u003c\/strong\u003e\n\u003cp\u003e\u003cstrong\u003eIs the F36-05-00 compatible with newer InnovairFlex models?\u003c\/strong\u003e\u003cbr\u003e\nNo, this specific part is designed for the legacy \u003cstrong\u003eDH400\u003c\/strong\u003e series.
