How to confirm if a part is compatible with my AF/BA module?

Check the module’s model number (e.g., AF500, BA702) and match with the part’s sub-series. Refer to the equipment manual or contact our technical team for verification against IEC 61010-1 standards.

What is the service life of these spare parts under normal operating conditions?

AF Series parts have a service life of 2,000-5,000 operating hours, while BA Series parts last 3,000-6,000 hours. Regular maintenance can extend lifespan by 30%.

How to handle parts damaged by environmental factors (e.g., corrosion)?

Replace damaged parts immediately to avoid secondary damage. Improve environmental controls (e.g., anti-corrosion coatings, dehumidifiers) and follow the prevention precautions in the table for new parts.
