Tetpor Liquid (Membrane)
TETPOR LIQUID filters are particularly suitable for sterilisation and particulate removal from aggressive chemicals (including acids, bases, and solvents) within a wide range of critical processing industries. The superior performance, strength, and durability of TETPOR LIQUID filters stem from the use of a single layer, high-security PTFE membrane, which has a high dirt holding capacity due to its high voids volume. This results in low pressure drops and long service life.
High flow rates are achieved due to the optimised pleat pack density and the superior design construction of TETPOR LIQUID filters. TETPOR LIQUID filters may be repeatedly steam sterilised or autoclaved up to 142 °C (287.6 °F), providing the user with assured security of performance.
