    Frequently Asked Questions
    Q1: What are the primary applications of these PTFE filters?
    They are widely used as vent filters for fermentation tanks and storage tanks, as well as for the sterilizing filtration of compressed air, oxygen (O2), nitrogen (N2), and other process gases.
    Q2: What is the maximum operating temperature for these filters?
    The maximum operating temperature for these PTFE filters is 80°C under normal working conditions.
    Q3: What are the pressure limits during operation?
    The maximum operating differential pressure (DP) is 0.55 MPa at 25°C and 0.1 MPa at an elevated temperature of 80°C.
    Q4: Are these filters biologically safe for pharmaceutical use?
    Yes, they are. They have an endotoxin level of < 0.25 EU/mL, exhibit no potential cytotoxicity in compliance with USP <87>, and meet USP <88> Class VI Biological Reactivity requirements for plastics.
    Q5: How can these PTFE filters be sterilized?
    ChallengeFilair® PTFE Capsule Filters can be autoclaved for up to 50 cycles. ChallengeFilair® PTFE Cartridge Filters are compatible with both autoclaving and Steam-in-Place (SIP) methods.
