Volvo air filter 21377909 plays a key purification role in the engine intake system. Through the synergy of multi-layer composite filter media (including ultra-fine glass fiber and polyester fiber gradient structure), it can intercept over 99.9% of particles above 0.3 microns, preventing dust from entering the combustion chamber to cause cylinder wear, piston ring failure and other faults. It also ensures sufficient air intake to improve fuel combustion efficiency, compatible with Volvo FH, FM series models.
The filter adopts high-strength temperature-resistant paper base material and polyurethane sealing frame, with a temperature resistance range of -30℃ to 80℃ and a dust holding capacity of ≥280g, which can maintain stable filtration performance in dusty, high-humidity and other complex environments. Its sealing frame adopts integral foaming technology, fitting closely with the air filter housing to avoid unfiltered air bypass. After airflow resistance test, the initial resistance is ≤1.2kPa, ensuring smooth air intake. The replacement cycle under normal working conditions is 1500-2000 hours, effectively extending the engine overhaul interval.
As a professional supplier, Ningbo Qiuning Trading Co., Ltd. provides both original and aftermarket 21377909 air filters. Original products strictly follow Volvo ISO 5011 standards, each batch tested for filtration efficiency and airflow resistance, suitable for long-distance transportation and heavy-duty operations with extremely high requirements for intake air quality; Aftermarket products pass third-party performance verification, with filtration accuracy reaching over 95% of the original, priced at 50%-60% of the original, suitable for regular working conditions and budget-limited scenarios, and both provide 12-month warranty.
During installation, check the integrity of the filter's sealing frame to avoid unfiltered air entering the engine due to improper installation. We have sufficient inventory, supporting global delivery within 48 hours, and our technical team can provide compatible model inquiry and replacement cycle suggestions.
