Four Steps to Match the Right Filter
Filter matching starts with the equipment and OEM reference, then confirms the filter type and relevant specification before an inquiry is submitted.
Confirm Equipment
Provide the machine model, engine model or serial number when available.
Select Filter Type
Choose air, engine-oil, fuel or transmission filtration according to the service requirement.
Check Reference Details
Use the OEM number, filter label, photos or dimensions to distinguish similar parts.
Submit an Inquiry
Send the confirmed details and required quantity for a product and availability check.
What to send with your inquiry
- OEM part number, if available
- Equipment or engine model
- Machine serial number, when available
- Photo of the existing filter or its label
- Required quantity and operating conditions
Result: the inquiry contains the details needed to check the replacement reference and related product options.

Frequently Asked Questions
Can these filters be matched to older Doosan and newer Develon equipment?
Send the OEM number, equipment model or serial number so the replacement reference can be checked.
How can I identify the right filter quickly?
The OEM number is the most direct reference. A clear photo of the current filter and the equipment model can help when the number is not available.
How often should a filter be replaced?
Follow the equipment manufacturer's service manual and adjust the interval for actual operating conditions such as dust, moisture and fuel quality.
Can packaging or labels be customized?
Include the packaging and labeling requirement with the inquiry so it can be assessed with the product specification.
Can you cross-reference a discontinued or unclear part number?
Provide every available reference, including the part label, equipment information and photos, for a cross-reference check.
Request a Chassis Parts Quote
Send the OEM number, chassis model or clear photos of the required part. The inquiry can then be checked against the available product information.
