47400039 Technical FAQ
Q: What is the purpose of a safety air filter compared to a primary filter?
A: A safety air filter is designed to protect the engine when the primary filter is removed for service or if the primary filter suffers structural damage. It acts as a final barrier against contaminants.
Q: How do I know when the 474-00039 needs to be replaced?
A: Unlike primary filters, safety filters should not be cleaned. They should be replaced every three primary filter changes or if the primary filter has been compromised.
Q: Does the 474-00039 fit Komatsu PC210-11 excavators?
A: Yes, this filter is a verified cross-reference for the PC210-11 series, providing identical fitment to the OEM safety element.
Q: What is Radialseal technology?
A: Radialseal is a design where the filter gasket creates a seal on the inner diameter of the housing outlet, eliminating the need for mounting bolts and providing a reliable airtight fit.
Q: Is this filter compatible with Develon DX-7 series models?
A: Yes, it is specifically designed for the latest Develon DX-7 generation, including the DX225LC-7 and DX255LC-7 models.
