Purifier Lifetime

Purifiers lifetime is based on:

• Average flow rate (slpm, scfm, Nm3/hr, scfh, etc)
• Duty cycle (hours per week gas is flowing)
• Impurity levels (ppm [part-per-million] levels of each impurity)

To determine the precise lifetime, collect the above information and contact SAES Pure Gas.
