Ultra filtration technique
State of the art uniform and narrow pore size distribution ensures a sharp cut off point and good flow rates, even at low water pressure. T-Safe® filters are tested to deliver safe and sterile water thanks to the accuracy in production of the filter membranes and pore size distribution.
The sharp cut-off point is proven by the validation in accordance to ASTM F838-05 for >Log7 bacteria retention for Legionella pneumophila, Pseudomonas aeruginosa, and Brevundimonas diminuta and fungi retention for Aspergillus brasiliensis (99.99999%). The filters are furthermore validated for up to 92 days lifetime through a field study.
More than 20 liters of water can pass through an unregulated filter depending on the water pressure.
A Tandrup constant flow regulator limits the water flow to 2, 4, 6, 8, 10 or 12 liters per minute, regardless of the water pressure.
