What is the standard replacement period for ZFA, ZFB, and ZFC series air suction filter elements?

Replace the element after 1 year of use or when one of the following occurs:
① When the pressure drop reaches 20 kPa at negative pressure:
ΔP(20 kPa) ② When the time until the vacuum pressure is reached is longer than the set time of the device:
set time (T) ③ When there are no remarkable changes in the operating environment conditions (vacuum ÷ release frequency, dust amount, etc.) determine how long it takes for ① or ② to occur (record data multiple times), and set the replacement period for future elements based on this data.
