Charlie, the DC itself is just temporary. Eventually the motor and blower will be mounted directly on top of the cyclone separator.
In get practically no carry over from the cyclone separator, so I will be building a filter box that mounts high and directly to the blower. I will be adding two more filters for even better air flow.
