Which cab air filter fits Case G-series wheel loaders?

The cab fresh air filter under part number 47880728 covers the 521G, 621G, 721G, 821G, 921F, 921G, 1021G and 1121G wheel loaders. It replaces the fresh air element in the cab HVAC system.

How often should I replace the cab fresh air filter on a Case wheel loader?

Replace the filter when airflow into the cab drops or the element looks clogged with dust and debris. Machines working in dusty conditions need more frequent changes. A clean filter keeps the operator cab comfortable and protects the HVAC system.

Do older Case loaders and G-series loaders use the same cabin filter?

No, the legacy B-series and the newer F/G-series use different filters. The 330014A1 panel suits 621, 821B and 921 machines while the 47880728 element fits the G-series loaders. Confirm your model before ordering or call (800) 909-7060.
