Vee-Pack™ PVC Pre-Packed 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 flush threads.
Vee-Pack has More Open Area than a Slotted Pre-Packed Screens. Whether it is sampling or water extraction/production, more open area will aid development and create a better well for its intended purpose. Vee-Pack is far superior in open area.
