Design Specifications

The device consists of a hand pump to bring water to the filter and a 120-micrometer mesh-prefilter for large particles, creating a two-way cross-flow that continually washes the membrane while pumping. It is based on a cross-flow ultra hollow fiber filtration membrane with a pore size of 0.01 micrometers (MWCO 150kDa), and it has a built-in flushing system with a backwashing syringe. It has a dry weight of 1.2 kg and its dimensions are 480 x 100 x 140 mm.

Technical Support

The filter can become damaged and therefore not work properly if it is exposed to direct sunlight for an extended time period, is exposed to very high or very low temperatures (under 5°C or over 45°C), or if it is physically struck. Damage can be determined through air leak testing which can be performed by the user and for which instructions are provided in the operations manual.
