  • I have clearstream 103 E -- is this pump a suitable replacement? what is difference with 103 ED Thankyo

    Some have a capacitor on top some don't have a capacitor. When they changed motors, they would change model numbers they all do the same cfm, have the identical vanes also. This pump will directly replace the other one.
