Compressed Air Filter for Sterile Process


Innovative Filtrex – IF filter is a wounded depth filter, with end caps, inner and outer guard made  from stainless steel. Consisting of a 3-dimensional borosilicate depth media, the IF Filter achieves  a void volume of 95%, ensuring a high containment capacity at high flow rates and low differential pressure. During operation,  the filter achieves a retention  rate of > 99.99998% related to 0.01 µm.
