The Midland Haldex DA35430 is a DRYest extended-service air dryer designed for system purge applications in transit service, including the Volvo 642070 application. Its multi-treatment desiccant cartridge runs five stages of cleaning to deliver dry system air, with a maximum working pressure of 150 psi, a safety relief setting of 160 psi, and a governor cut-out of 130 +/- 5 psi. Inlet airflow capacity reaches 35 SCFM, and the pressure drop is 2.5 psi at 15 SCFM and 120 psi. The integrated governor reduces application costs, while the built-in 140-watt heater guards against freeze-up. Regeneration purge drain uses a silencer for quiet operation. Turbo protection requires a 35 psi minimum inlet. Call us to confirm proper fit for your application.
