Maintenance suggestions: During installation, it is necessary to check whether the sealing surface of the flange is in good condition. Use the original factory sealant gasket and tighten the bolts according to the specified torque. This is to prevent air leakage or damage to the components due to improper installation.

Maintenance Reminder: Check the valve core for any jamming (disassemble for cleaning) and the springs for fatigue every 6 to 12 months. Replace the aging seals in a timely manner. If the pressure rebounds too quickly after depressurization or cannot be completely relieved, investigate whether the valve core seal has failed or if the control signal is normal.

The compatible check valve kit can serve as an economical alternative to the original factory kit. However, in high-pressure, high-frequency operation or in situations with extremely high reliability requirements, it is still recommended to choose Atlas Copco's original factory parts as the preferred option.

The PD/PDP filter kit is a crucial part for ensuring the quality of compressed air, directly affecting the lifespan and product quality of downstream equipment. If you need to confirm the specific model of the filter (such as the corresponding PD500, PDP1000 and other shells) or detailed parameters

Replacement and Maintenance Precautions Cycle Compliance: Follow the specified cycle in the equipment manual for replacement (e.g., air filter every 2000 - 4000 hours, oil-gas separator every 8000 - 12000 hours). In harsh environments (dusty, high temperature), check and replace in advance. Installation Specifications: Release system pressure before replacement and clean the interior of the filter housing. The sealing parts of the new filter need to be coated with clean lubricating oil (for oil filter) or compressed air (for air filter) to ensure a reliable seal. Tighten the end cover or housing with the specified torque to avoid over-tightening which may damage the shell or under-tightening which may lead to leakage. Kit Integrity: The original factory kit includes all necessary components (such as sealing parts, small gaskets), and when replacing, all components must be updated. Do not mix and use old parts.

Key points for replacement and maintenance: Selection matching: Use the original factory connectors of the corresponding model. Confirm the interface specifications, pressure grade and material. Avoid leakage or connection failure due to mismatched dimensions. Installation guidelines: Pneumatic/oil circuit connectors: Wrap sealing tape or replace the new seal, tighten according to the specified torque, avoid over-tightening which may cause thread damage. Electrical connectors: Ensure the pins are aligned, prevent damage caused by forced insertion or removal, tighten the locking structure . Regular inspection: During daily maintenance, check if the connectors are loose, corroded or overheating . Address abnormal situations promptly.
