Context: "В инерционных ловушках системы газотранспорта происходит очистка техуглерода от посторонних включений."

"In the gas transport system’s ???? catch tanks, the carbon black is cleansed to eliminate foreign substances."

One could write "inertial", but is that a false friend? I was given a help file, in which these инерционные ловушки are called "low-response catch tanks". I know that one of the definitions of "инерционный" is "slow-response" (as in "delayed-action"), but what is "low-response"? Should I go with "inertial," or just blindly follow the help file, even though I don't know if it was supposed to be "low", or "slow"? Or, is there a totally different term?
