Function / Role in the Engine
The breather filter (crankcase ventilation element) is responsible for:
· filtering oil vapors and contaminants from crankcase gases
· maintaining correct crankcase pressure
· preventing oil mist from entering the intake system
· reducing engine emissions and oil consumption
· improving overall engine efficiency and durability
Key Features
· effective separation of oil particles from blow-by gases
· stable airflow through the crankcase ventilation system
· high resistance to clogging under heavy-duty operation
· durable filtration media for long service life
· reliable performance in industrial and off-road applications
Applications
Suitable for a wide range of equipment powered by Perkins 1100 Series engines, including:
· construction machinery
· agricultural machines
· industrial power units
· generator sets
