Our filter cartridges for tricky and sterile applications are available in various lengths and versions. We differentiate between pleated absolute filter cartridges (down to beta 10,000 – 99.99%) and membranes (Bacterial Challenge Test ASTM F838-05). Sterile filters retain various microorganisms such as Brevundimonas diminuta, Ralstonia pickettii, Lactobacillus brevis, Saccaromyces cerevisiae and Legionella pneumophila, depending on application.
During production, every filter is assigned a batch number and test report so as to guarantee traceability at all times.
