Description
Spirax-Sarco FT-30 Float & Thermostatic Steam Trap — 1-1/2″ | 30 PSI
The Spirax-Sarco FT-30 is a high-quality float & thermostatic (F&T) steam trap engineered for continuous, automatic discharge of condensate and air from steam systems. With a 1-1/2″ connection size and a 30 PSI pressure rating, this trap is well-suited for a wide range of commercial and industrial steam heating applications where reliable condensate management is critical to system efficiency and equipment longevity.
How It Works
The FT-30 combines two proven mechanisms in a single trap body. The float valve responds continuously to condensate levels, opening to discharge condensate as it accumulates and closing when steam is present — ensuring no live steam is lost. The integral thermostatic air vent automatically purges non-condensable gases (air) at startup and during operation, improving heat transfer efficiency and preventing air-binding in the system.
