The main distinguishing feature between these bulk bag dischargers is the hopper design. \* Flo 40 [bulk bag dischargers](https://academy.spiroflow.com/bulk-bag-discharger-selection-guide/) feature an economical, 40° sloped hopper suitable for discharging a wide range of ingredients. \* Flo 60 bulk bag dischargers have a 60° sloped hopper for discharging poor flowing ingredients. \* Iso Flo bulk bag dischargers come with either the 40°or 60°hopper complete with a bag outlet clamping system enclosed in an isolation chamber for total **dust containment**. Iso Flo bulk bag dischargers are used to discharge any ingredient that requires a high level of dust containment such as hazardous, toxic or sanitary products. The prime factors in determining which type of bulk bag discharger is best suited to your application are the type of ingredient, the type of bag to be discharged and the allowable level of dust emissions. \* The Flo 40 bulk bag dischargers are suitable for easy to moderately flowing ingredients such as pellets, granules and some powders in outlet spouted and porthole style bags. \* The Flo 60 bulk bag dischargers can handle a wide variety of ingredients and bag styles. \* Iso Flo **bulk bag dischargers** can handle easy to poor flowing ingredients in outlet spouted bags. | **Flo 40** | **Flo 60** | **Iso Flo** | | --- | --- | --- | | ![Flo 40](https://academy.spiroflow.com/hs-fs/file-14213458-jpg/images/discharger-floeasy-1-med.jpg?width=149&height=281&name=discharger-floeasy-1-med.jpg) | ![Flo 60](https://academy.spiroflow.com/hs-fs/file-14213447-jpg/images/discharger-flo-1-med.jpg?width=175&height=238&name=discharger-flo-1-med.jpg) | ![Iso Flo](https://academy.spiroflow.com/hs-fs/file-14213468-jpg/images/discharger-isoflo-2-med.jpg?width=175&height=230&name=discharger-isoflo-2-med.jpg) | | **Ingredient** | | | | - Easy to moderate flowing pellets, granules, flakes and some powders | - All ingredients, including poor flowing - Granules, pellets, powders and fibers | - All ingredients including hazardous, toxic, sanitary | | **Bag Type** | | | | - Lined or unlined, with outlet spout - Lined, with porthole in outer bag. | - Lined or unlined, with outlet spout - Unlined, with plain bottom - Lined, with porthole in outer bag | - Lined or unlined, with outlet spout | | **Selection Criteria** | | | | - Low investment - Ingredient easy to moderate flowing | - Difficult flowing or compacted ingredients - Dusty ingredient - Any bulk bag configuration | - Dust containment is critical |
