4 CFM Regenerative Desiccant Dryer, Walker Filtration, PD004N

Pro SFD series compressed air dryers from Walker Filtration deliver high quality compressed air for critical applications requiring an ultra-low pressure dew point. SFD dryers use the principle of pressure swing adsorption (also called heatless drying) to strip trace amounts of water vapor from compressed air lines, yielding dew points as low as -40F.

SFD dryers have been designed for ease of installation and simple operation. Models PD004N through PD0035N can be floor or wall mounted, in either a horizontal or vertical position. The simple diagnostic panel displays key operating information and service alerts. A simple to remove aluminum shroud allows quick access to all valves and desiccant cylinders.
