Franklin Subdrive Utility Filter. Part #226115910. Shipped with USPS . Used as Electrical Line Power and Drive output filter for the Franklin Water SubDrive Utility . Technically barely "used" but I used this at a trade show to show potential clients, practically no real time on it. This 120/240 Single phase. Please contact Franklin Water if you have any other questions. Please check out my feedback, I try to treat others how I'd like to be treated.
