Designed with the small quantity wine maker in mind. Compact enough to filter anywhere. Built in pump and motor, operates on 3 filter pads. Incorporated drip tray and drainage tube for convenience. Wine is always crystal clear! The Mini Jet uses three filter pads when in operation (purchased separately). Start with a #1 Coarse pad (item 5272), then go to a #2 Polishing pad (item 5274), and then if needed finish it off with a #3 Sterile pad (item 5276).
