F-03 high-efficient adsorbent is mainly ingrediented by molecular sieve. Under normal temperature, it can effectively adsorb many kinds of sulfur fluoride such as SOF2, SO2, S2F10O etc., acidic materials and moisture. It is suitable for application of SF6 breaker, SF6 totally closed assembled electrical equipment and other SF6 electrical appliance. Besides, it can also used for refining SF6 as well as purifying the gas with the above similar impurities.
