Reviews Description: Eastman Outdoors offers High-Quality cooking products that outdoor chefs are hungering for. Products developed are done in connection with leading chefs to adapt professional-grade equipment for outdoor cooking: equipment that's ideal for backyard get-togethers, tailgating and camping. The battery-powered oil filter pump is a patented filtration method that allows you re-use your cooking oil. Running on 3 "D" batteries (not included), the pump automatically helps to elimate messes and spills when transfering used cooking oil into a storage container. You will receive 3 replacement filters, and additional filters can be purchased seperately.
