Part #: AFT4

These disposable airlfow filters remove airborne bacteria; use with the TSD107B and other 35mm breathing circuits. AFT4 VBMax™ filters provide a high degree of protection for subjects and equipment, and the low resistance allows for accurate testing results.

Independent laboratory tests have verified that this pulmonary function filter is highly effective. VBMax™ consistently filters out more than 99.99% of bacteria and 99.99% of viruses. At the same time, VBMax™ easily surpasses published ATS recommendations for flow resistance in pulmonary function instrumentation, which suggest resistance should be below 1.5 cm H2O/L/sec at flow rates of 14 L/sec.
