Increase both the shortening life and quality of your oil with the Pitco RP18 portable filter system with a reversible pump. This easy-to-use and easy-to-store mobile item removes crumbs and sediment from the oil that, if ignored, can cause flavor transfer and a quicker breakdown of the shortening. The extra large filter area boasts a shortening capacity of 75 lb. and thanks to its low profile design, fits effortlessly under most fryer drains. With a reversible pump, this unit will draw oil from one direction out of the fryer and then recycle freshly filtered oil back into the fryer for increased efficiency. If your fryer doesn't have a built-in filtration system, this unit is the perfect way to get the same great benefits without purchasing a whole new fryer!
