Atlas Copco Compressed Air Filter PD75+

Warning: This procedure requires trained personnel with PPE!

On filters with manual drain valve, open the latter at regular intervals to evacuate collected dust or liquid

In case an automatic drain valve or a solenoid timer drain is installed, manual draining can be carried out by turning the connection nipple of the automatic drain valve counterclockwise

NOTICE! When the filter has to process air with a temperature higher than the specified maximum temperature, the filter's lifetime will be reduced considerably

NOTICE! The hand-tool icon on the figure indicates the items provided in a dedicated filter kit

Check for any leakages at the bottom of the filter bowl (connection of manual and automatic drain) during normal filter operation

If any leakage is observed, replace the drain according to the instruction from section Drain replacement

Isolate the filter from the air net

Depressurize the filter by turning the connection nipple of the automatic drain valve counterclockwise or by opening the manual drain valve

When maintaining the filter, keep in mind the following

• On filters with manual drain valve, open the latter at regular intervals to evacuate collected dust or liquid

• In case an automatic drain valve or a solenoid timer drain is installed, manual draining can be carried out by turning the connection nipple of the automatic drain valve counterclockwise

NOTICE! When the filter has to process air with a temperature higher than the specified maximum temperature, the filter's lifetime will be reduced considerably

NOTICE! The hand-tool icon on the figure indicates the items provided in a dedicated filter kit

Start by isolating the filter housing from the compressed air flow

• For a filter without inPASSTM valve, this is done externally

• For a filter with inPASSTM valve, this is done by rotating the inPASSTM valve into inPASSTM mode, following the instructions in section inPASSTM instructions

Depressurize the filter by turning the connection nipple of the automatic drain valve counterclockwise or by opening the manual drain valve

NOTICE! When the filter has to process air with a temperature higher than the specified maximum temperature, the filter's lifetime will be reduced considerably

WARNING! For safety reasons, the inPASSTM should never be operated while the bowl is dismounted (fully or only partly) from the head

NOTICE! When in inPASSTM mode, no contaminants are filtered and pressure drop over the housing will be higher. Therefore the duration of the service events must be kept as short as possible

WARNING! The table below indicates for every size range the expected torque values when rotating the inPASSTM valve, the maximum torque that can be used to rotate the inPASSTM valve and the recommended tool to use Maximum torque values should not be exceeded to prevent damage to the inPASSTM valve

NOTICE! The hand-tool icon on the figure indicates the items provided in a dedicated filter kit

NOTICE! A small amount of acid-free vaseline may be applied to the threads and O-ring of the bowl to facilitate the assembly. No lubricant of any sort should be used on the filter element seal or inPASSTM seals

On filters with manual drain valve, open the latter at regular intervals to evacuate collected dust or liquid

In case an automatic drain valve or a solenoid timer drain is installed, manual draining can be carried out by turning the connection nipple of the automatic drain valve counterclockwise

Before operating the inPASSTM, please check if the circlips is correctly positioned (supported by the inPASSTM groove and the horizontal face on top of the filter head) just below the hexagonal nut. In case of any doubts, please contact your supplier
