The Midland Haldex DA34100 PURest air dryer delivers 5-stage multi-treatment desiccant cleaning at a flow capacity of 34 SCFM and a maximum working pressure of 150 psi, with a safety relief pressure of 175 psi and secondary pressure protection at 235 psi. The internal purge volume is 210 cu. in., and the 12V, 95W built-in heater prevents freezing across an inlet air temperature range of -40°F to +175°F. Integrated turbo protection limits pressure drop to 2 psi at 15 SCFM and 120 psi. The universal mounting bracket is compatible with Pure Air Plus, DRYest, AD type, and SS type air dryer bolt patterns, easing retrofit installations. OEM cross-reference N4253AA. Also referenced as MDDA34100. Call us to confirm proper fit for your application.
