Donaldson LifeTec depth and membrane filters

Donaldson LifeTec depth and membrane filters for the pre-, fine and sterile filtration of liquids are designed to lower production costs and increase process reliability. With retention rates from 0.2 to 100 microns and lengths up to 40", the LifeTec filters incorporate a stable PP liner and offer an increase in the dirt-holding capacity increasing the number of sterilisation cycles.

The liner features a new rhomb-shaped structure, which is claimed to offer a better pressure stability and torsional stiffness than conventional liners, increasing the process reliability. The larger filter surface, the high retention capacity as well as the mechanical and thermal stability of the pleated filter media can lead to higher volume flows and an extended life cycle of the filters. In addition, users can also benefit from a lower pressure loss: the company said it is possible to either save energy for generating pressure or use fewer filters in an accordingly smaller housing.
