A system for preventing error operation of air pressure operation type circuit-breakers is provided to prevent enormous damage according to malfunction and to lengthen reliability and lifetime of a minute operation tool by preventing beforehand malfunction of air pressure operation type circuit-breakers. A system for preventing error operation of air pressure operation type circuit-breakers contains a filter 1(1), a refrigerated air dryer(2), a filter 2(3), an adsorption unfired pressure reduction regenerative air dryer(4), a filter 3(5), a filter 4(6), a check V/V(7). The filter 1 filters particles of which is a size is 40mum or greater in fine dust of compacted air flown in from an air compressor. The refrigerated air dryer removes oil . moisture of the compacted air passing through the filter 1. The filter 2 filters particles of which is a size is 5mum or greater in the fine dust of the compacted air passing through the refrigerated air dryer. The adsorption unfired pressure reduction regenerative air dryer dries the compacted air passing through the filter 2 to -65°C. The filter 3 filters particles of which a size is 0.3mum or greater in the fine dust of the compacted air passing through the adsorption unfired pressure reduction regenerative air dryer. The filter 4 filters particles of which is a size is 0.01mum or greater in the fine dust of the compacted air passing through the filter 3 and delivers the particles to air tank. The check V/V is positioned between the filter 4 and the air tank.
