Stainless Steel Mechanical Step Screen For Wastewater Treatment Plant
Product Description
Step type fine screens have unique capabilities:
-Step Screen is totally self cleaning without flushing or brushes. This gives unrivaled
capacity, resulting greater value.
- Unique sealed low friction bottom step without plastic spacers gives the highest separation
of any step screen on the market, making it an excellent replacement for perforated screens.
- Self cleaning discharge without plastic spacers.
- Robust construction with thick bars.
- Big steps along the whole bar length ensures high conveying capacity even for big objects.
- Linkage transmission = no limitations in min or max water level.
- Flexible mounting angle up to 60 degrees for compact installation in short channels.
- Innovative support legs simplify installation and enable the screen to be easily rotated out
of the channel for service.
- Enclosed, safe & hygienic with easy to open access doors.

Features
♦ The driving unit is directly driven by cycloidal gear reducer or helical gear reducer which
shows the nature of working stability, low noise, big load capability and high efficiency in
conveying.
♦ Simple structure with compact size, easy to install and move. Device can self-clean up
while working, easy to maintain.
♦ Easy to operate, can be controlled directly on the spot or remote.
♦ Include overload protection device, machine will shut down automatically when
malfunction happens to avoid damage.
♦ When the device width exceeds 1500mm, will be made into parallel machine to ensure the
overall strength.
