13-1 Filters Check the filters frequently when commissioning the unit. The rate at which they will clog will depend on how well the air circuits were cleaned. Frequency of servicing The filter life depends essentially on the amount of dust in the air and the efficiency of the filtration system. The filtration quality cannot be maintained if the filter medium has been damaged during maintenance. -
