Johnson Screens Vee-Pack PVC Prepacked Screens

Some subsurface conditions, such as heaving and very-fine sands, make conventional filter pack placement difficult or impossible.  The solution is a Johnson Screens Vee-Pack screen that has an integral filter pack that creates a filter pack that is 100% void-free.  Available with either Schedule 40 or 80 threads.
