Two models of the MDE1225 series offer 12 Vdc and 24 Vdc inputs. Both provide a maximum airflow of 95.3 cfm with a maximum static pressure of 0.281" of H2O and a maximum audible noise figure of 46 dBa. Four models of the MDE1451 series include 24 Vdc and 48 Vdc units that deliver a maximum airflow of 205 cfm, maximum static pressure of 0.521" of H2O, and a maximum noise level of 49 dBa.
