Model No: SFS350-2CI

Auto Backwash, 350 L/min

Puretec SFS350-2CI Sediment Filtration System
The Puretec SFS-2CI Series sediment filtration system removes sediment, silt, sand and other particulate preventing the build-up of sludge in your pipe work, hot water systems and appliances. The system now incorporates new media that filters down to 3 micron.

Puretec SFS-2CI Series deliver a fully automatic and highly dependable control valve, which helps minimise energy and water waste. Features a fully automatic operation that provides a reliable design and simple programming for ease of use. This system effectively protects your system with little or no maintenance by automatically back washing the graded filter bed.

Operating Conditions: 1. Not recommended for colloidal particles. 2. Water turbidity and particle size will affect recommended flow rate. 3. The flow rate while the filter backwashes, needs to be equal to the stated service flow to maintain proper backwash functionality, which is critical for optimum performance of filtration systems. 4. Operating pressure 200 - 690 kPa, pressure loss 100 kPa.
