VISIT THE SITE DEDICATED TO SPIRAL FILTERS
Spiroscreen is the range of continuous spiral filters entirely produced by GTS from DN100 to DN600.
The filters are constructed by continuously winding a triangular section profile on round profiled lines, each intersection between the triangular and round profile is resistance welded (RW).
The spiral filters have a wide passage surface that allows for high flow rates to be achieved while keeping the water speed very low.
This allows for optimum development of the well:
• Minimum hydraulic resistance
• Reduction of fouling formations
• Less input of impurities (sand) that can damage the pump over time
• Removal of fast and complete perforation fluids.
The construction is made of stainless steel, a first choice material to withstand stress during installation or when subject to pressures and corrosion.
