It is compatible with the Tx151C, Tx200C, VM110P, FTV110C, FTV150C, and FTV190C models across the Tx, VM, and FTV series. This part is used by HVAC technicians and hydronic heating professionals to automatically remove trapped air from a closed-loop heating system. Air pockets in a hydronic system cause noise, reduce heat transfer efficiency, and can damage the circulator pump over time. An automatic air vent eliminates this problem by releasing air continuously without requiring manual intervention. The 85294 is a direct OEM-equivalent replacement, which means it fits and functions exactly as the original part. HVAC service technicians use this type of component during boiler installations, system startups, and repair calls. When a boiler system is filled or refilled with water, air naturally enters the lines. The auto air vent sits at a high point in the system and allows that trapped air to escape while keeping the water sealed inside. This keeps the system running quietly and at full heating capacity. Hydronic heating contractors who work on NTI boiler systems should keep this part on hand to avoid extended downtime during service calls. The 85294 is sold individually and is a nonstock item, so ordering in advance is recommended. It is the correct replacement vent for all listed NTI boiler models and ensures reliable, long-term performance in residential and light commercial hydronic heating applications.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eDirect replacement auto air vent for NTI Tx, VM, and FTV series boilers\u003c\/li\u003e\n\u003cli\u003eCompatible with Tx151C, Tx200C, VM110P, FTV110C, FTV150C, and FTV190C units\u003c\/li\u003e\n\u003cli\u003eAutomatically purges trapped air from closed-loop hydronic heating systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe NTI 85294 Auto Air Vent IWC is an OEM-equivalent replacement part that keeps NTI condensing boilers running quietly and efficiently by continuously removing air from the hydronic loop.
