  • Can be designed to pivot out of the channel

  • 6 mm thick side frames

  • 6 mm (0.24-inch) to 1 mm bar spacings available

  • Low overall height allows for low ceiling height

  • Fully enclosed

The Model ESR Stair Screen is an automatic, self cleaning, fine screen for primary screening or sludge screening in municipal and industrial sewage treatment installations. The design of the Stair Screen allows for easy installation in new and existing facilities without channel modification. With a maximum setting angle of 57°, the Stair Screen has a compact overall footprint.


Construction

The side frames of the Stair Screen are constructed of formed stainless steel plate having a thickness of 0.24 inch. The lamellas in the screening area are stainless steel. The lamellas in the transport area can be stainless steel or a corrosion resistant, UV stabilized synthetic material, depending on the overall height of the screen. The drive system consists of a gear reducer, motor, and a dual chain transmission system with automatic chain tensioning devices. To prevent corrosion, ease maintenance and ensure years of reliable service, the drive system is located completely above the maximum water level, and the gear reducer and motor are encapsulated away from the corrosive atmosphere of the channel. All moving parts of the drive system are protected by removable enclosure panels. The screen portions above the channel can be equipped with removable panels to enhance aesthetics and reduce odor.


Post-Screening Devices

In addition to primary screening devices, Vulcan Industries offers a wide array of post-screening and dewatering devices. The Model EWP Washing Press and Model ESP Screw Press provide dewatering and transport for screenings. Connect multiple screening devices to a single post-screening dewatering and compacting device with a conveyor from Vulcan Industries. To assemble the most cost effective and efficient array of screening and post-screening devices, please contact your Vulcan Industries representative.
