Description
The Spirax-Sarco FT-30 is a high-quality Float & Thermostatic (F&T) steam trap engineered to provide continuous, efficient condensate drainage in a wide range of steam heating and process applications. With a 1″ connection size and a 30 PSI maximum working pressure rating, this trap is well-suited for low-to-medium pressure steam systems found in commercial and industrial HVAC, process heating, and hydronic steam distribution.
As a float and thermostatic design, the FT-30 combines two proven mechanisms in a single body: a float-operated main valve that responds immediately to condensate load, and a thermostatic air vent that purges non-condensable gases on startup and during operation. This dual-action approach ensures maximum heat transfer efficiency and prevents air binding — a common cause of poor system performance.
Spiax-Sarco is a world leader in steam system solutions, and the FT-30 reflects their commitment to precision engineering, long service life, and minimal maintenance requirements.
