Indications for saturation of the exhaust filter:
● higher current consumption of the motor
● increased emission of operating fluid mist at the gas outlet
● increased pressure in the operating fluid separator (pressure gauge indicator in the red area).
Continuous monitoring of the filter resistance
► To continually monitor the filter resistance, use a manometer from
