Description
The Mepco (Dunham Bush) ML9621 is a 1-1/4″ Float & Thermostatic (F&T) steam trap designed for dependable condensate removal in low-pressure steam heating systems. Carrying the model designation 44-515A and rated at 15 PSI, this trap combines a float-operated main valve with a thermostatic air vent to deliver continuous, automatic condensate drainage while preventing steam loss and eliminating air binding.
Float & Thermostatic traps are the preferred choice for heat exchangers, unit heaters, coils, and other steam-heated equipment where a continuous and high-volume condensate load must be handled efficiently. The float mechanism responds instantly to condensate levels, while the integral thermostatic element purges non-condensable gases — keeping your system running at peak thermal efficiency.
