I had an EAC once, the cell was 2' X 2' X 3'long and weighed about 30#. Old thing still worked too! Customer was very proud of his self-cleaning EAC. I took the cell out to his driveway and cleaned it with a mild coil cleaner mix, it was beautiful. He loved it and I was going to get a picture of it next time I went there. But I didn't work at that company next year. He had it still in place in his return connected to a Lennox Duracrack furnace, EAC was bigger than the furnace!
