Baldwin PA3787 Axial Seal Inner Air Filter Element
The Baldwin PA3787 axial seal inner air filter element is designed to work inside the Baldwin PA3606 outer air filter, providing an additional stage of air filtration for compatible agricultural machinery, heavy equipment and commercial vehicles.
As part of an engine air filtration system, the inner element helps prevent dust, dirt and other airborne contaminants from reaching the engine's combustion air system. The axial seal design incorporates securely attached metal end caps and an integral raised gasket to help create a reliable seal when correctly fitted.
The PA3787 is listed for selected Claas, Liebherr and New Holland equipment, as well as M.A.N. trucks.
Inner Air Filter for Heavy-Duty Applications
The PA3787 is an inner air element, rather than the primary outer filter. It is designed to fit inside the Baldwin PA3606 outer element.
This type of filtration arrangement is commonly used on equipment operating in dusty or demanding conditions, including agricultural machinery and heavy-duty vehicles. The inner element provides additional protection for the engine intake system when used as part of the specified filter assembly.
Axial Seal Construction
The Baldwin PA3787 features axial seal construction with securely affixed metal end caps and an integral gasket.
The gasket is included as part of the filter element and is designed to provide the sealing interface between the filter and its housing when correctly installed.
A properly seated filter is essential to help prevent unfiltered air from bypassing the filtration element.
Compatible Outer Element
The PA3787 is specified to fit inside Baldwin PA3606.
For applications using both elements, check that the existing outer and inner filter numbers match the equipment manufacturer's requirements before ordering.

Why the Inner Air Element Matters
Heavy equipment and agricultural machinery can operate in environments with significant amounts of dust and airborne debris. Maintaining the complete air filtration system is therefore important for protecting the engine's intake air supply.
The PA3787 provides a replacement inner air filter element for compatible applications and should be used as part of the specified filtration system.
Always follow the equipment manufacturer's service instructions when inspecting, cleaning or replacing air filter elements. Replace the element if it is damaged or at the manufacturer's recommended service interval.
