Maybe this is common knowlege,maybe not.Since I always look at worse case scenarios. Maybe someone can chime in since I have no direct knowlede on the answer, but I'm assuming it's a yes. But, if say the opg or anything else in the motor goes it could take out your pd blower with it? If you have a centri you'd wouldn't be out that cost as well. Just something to think about if that's a concern.
