The STEPGUARD® contains innovative design solutions for many of the outdated designs currently used on similar screens, and represents the strongest and most durable fine screen on the market.
A reliable fine screen for in-channel or tank mounting, the ST screen separates out over-size solids and automatically conveys out captured screenings, cleaning itself in the process. Flow range 50 to 2200 liters per second (1-50 MGD).
Features and Benefits:
New design of bar element fastening enables quick replacement
Better alignment of the bars enables SPIRAC® to build screens that have much finer space openings than any other screens of this type.
The doors and covers, as well as the enclosed motor compartment, have been designed to provide easy access and improved safety.
Hinged “Grit Flap”, allows passage of suspended grit without spacer erosion, bar wear, or jamming. Flap rides on bottom step pushing flow up and away from bottom spacers.
A new “stop-in-home position” solves the old “roll-back” problem.
A heavy-duty gear motor and transmission, including a unique type of bearing, provides an extremely long life cycle.
No chains, therefore no chain wheels in water
5mm frame and 3mm bars
Long life bearings with automatic greasing
Virtually maintenance free.
