Hand sanitizing foam dispensers help reduce infection and the spread of harmful bacteria. This countertop unit has a heavy weighted base so it will not tip over. Use in retail shops, banks , hospital, lobbies, cafeterias and restaurants. The dispenser holds 1200ml of foam sanitizer, about 40 oz. There are 3 volume settings so you can adjust how much foam is dispensed in each use. Six AA batteries (not included) are required. Our countertop version comes with a drip tray to minimized spillage.
