Common questions

What equipment does it fit?

It fits DEVELON machines that call for part number 400504-00408. Check the part number in your machine's parts manual, or on the element currently installed, before ordering.

What does the inner element do compared to the outer filter?

The outer (primary) element does most of the filtering. The inner element is a backup that protects the engine if the outer element fails, and it keeps the intake covered while the outer element is out for cleaning or replacement.

How do I know the inner element needs replacing?

Replace it if you find dust or dirt on the inner element or on the clean side of the housing, which usually means the outer element has leaked or failed. Also replace it if the element is damaged or has been cleaned. Otherwise follow the service interval in your DEVELON operator's manual.
