The high-capacity Dual Screen System from Screenco Systems is constructed of aluminum with stainless steel screens, with a collection sump and a high-capacity 6-inch drain. The screen has two 3/8-inch-gapped stainless steel bar screens at opposing angles, with the front screen virtually self-cleaning. It is a non-mechanical, simple way to remove large pieces of trash, rocks and other debris from the flow stream. This unit has a 4-inch telescoping inlet hose that moves laterally and can be easily connected to any vacuum truck or other flow stream. The system is portable, and the 19.5 square feet of screening area allows for continued use and is easy to rake clean to the garbage drain tray. It can treat over 500 gpm. Various-gapped screen sizes are available. 208/790-8770; www.screencosystems.com.
