Description

The 9Y3879 air filter is a heavy-duty cylindrical air filter designed for diesel generator set air intake systems.
We make this filter as an OEM replacement, supplying generator maintenance companies, industrial service providers, and filter wholesalers who require stable quality and long-term supply, rather than branding.

This model is widely used in generator overhaul, routine maintenance, and fleet service operations, where reliability, airflow stability, and dust-holding capacity are critical.

As a filter factory, we supply this product directly, without intermediaries, supporting small batch to bulk orders.

Please confirm the OEM part number 9Y3879 and the required dimensions before ordering.
This air filter is designed for diesel generator air intake systems and is supplied as an OEM replacement, not a genuine OEM brand part.
For generator maintenance projects or bulk procurement, please verify compatibility with your equipment model or contact us for confirmation.
