Description
The Hoffman Specialty 404204 is a Series H Cast Iron Float & Thermostatic (F&T) Steam Trap engineered for reliable, continuous condensate discharge in low- to medium-pressure steam systems. Featuring a 3/4″ NPT connection, a 75 PSI maximum working pressure rating, and a precision .166″ orifice, this trap delivers consistent performance across a wide range of commercial and industrial heating applications. An integrated thermostatic air vent allows for rapid air and non-condensable gas purging at system startup, reducing warm-up times and improving overall system efficiency.

Application
The FT075H-3 is ideal for use on unit heaters, heat exchangers, radiators, and other steam heating equipment where reliable condensate drainage and air venting are critical. The float mechanism responds immediately to condensate load changes, while the thermostatic air vent ensures non-condensable gases are purged efficiently — helping to maintain peak heat transfer performance and protect system components from water hammer and corrosion.
