Description
The Xylem-Hoffman Specialty 404271 is a Series I Cast Iron Float & Thermostatic (F&T) Steam Trap designed for reliable, continuous condensate drainage in low-pressure steam heating systems. Engineered to handle both condensate and non-condensable gases simultaneously, this trap combines a float mechanism with a thermostatic air vent for superior system efficiency and reduced energy waste.
Product Overview
The Model FT015I-4 delivers dependable performance in a wide range of steam heating and process applications. The cast iron body provides long-lasting durability in demanding hydronic and steam environments, while the integrated thermostatic air vent ensures automatic venting of air and CO₂ at startup and during operation — preventing air binding and keeping your system running at peak efficiency.
