Watson McDaniel Diffusers WDF Series

The WDF Diffuser was specifically designed to cushion the discharge from steam or air traps. They work to suppress the high velocity discharge often associated with blast-type steam traps in order to reduce noise, erosion and waterhammer. This compact unit is made from Stainless Steel. It is available in 1/2" and 3/4" NPT and SW connections. The WDF1 Diffuser can be fitted to the outlet of any steam or air trap discharging to the atmosphere. Maximum Operating Pressure is 900 PSIG. The WDF2 Diffuser can be fitted to the outlet of any steam or air trap discharging to a condensate return line. Maximum Operating Pressure is 450 PSIG.
