Per escavatori, pale, frantoi e cantieri polverosi, il filtro aria non va scelto solo per codice. Verificare diametro esterno, interno, altezza, tenuta, media filtrante e spazio reale di montaggio.
Un filtro errato può aumentare la restrizione d’aspirazione, danneggiare la guarnizione o far passare polvere nel motore. Nelle flotte miste i riferimenti vanno confrontati con il vecchio filtro e la macchina. Construction machinery application and engine air filter category show the wider product range.
Perché le dimensioni rendono sicuro il ricambio
The key air filter parameters are height, outside diameter, inside diameter, seal shape, seating depth, housing type and whether a safety element is used. If one of these points differs, the filter may not seal even when the cross-reference number looks close.

FAQ
Is one cross-reference number enough?
No. A cross-reference number is only a starting point; dimensions, seal, housing, media and working conditions still need to be checked.
Which models should be included in an inquiry?
Send the main number, possible replacements, old filter photos, measured dimensions and machine model, for example C12004, P955961, P153551, P772579, P185485, 1869993, 21834205 or R005061.
Can OEM/private-label packaging be supported?
Yes. GUOHAO can support samples, carton labels, export marking and checks before bulk production.
