Maintenance conditions vary depending on the gas conditions. Replacement intervals for
the filter and activated charcoal should be determined in accordance with the operating
conditions.
• Used eight hours a day, pump life will be approximately one year.
• Filter life is about 50 hours. (if measured gas contains isopropyl alcohol of concentra
tion 500 ppm, and flow is 500 ml/min.)
