The site, and the cyclones, look great. I notice you have right and left handed cyclones, both fitted with the same handedness of blower. Bill Pentz suggests that matching the direction the air swirls in the cyclone to the blower rotation direction should be a bit more efficient than a mismatch. Since you have both types, it might be interesting to measure the airflow to see if there is a measureable difference.
