Donaldson P124866 Safety Air Filter Round FVG 18 Inch

The Donaldson P124866 is a round safety air filter designed for heavy-duty equipment air intake systems. This secondary filter element serves two critical functions: acting as a backup to the primary air filter and protecting the engine during primary filter servicing.

Key Features:

• 18-inch length with 8.65-inch outer diameter and 7.06-inch inner diameter
• Round style construction with pleated media for maximum filtration surface area
• ISO 5011 efficiency test standard certification
• 15 micron nominal filtration rating
• Maximum operating temperature of 250°F
• Outside-to-inside airflow direction
• FVG family design for Donaldson FVG16 Cycloflow air cleaners

Protection Functions:

• Serves as backup filter in case of primary filter damage or improper installation
• Prevents contaminants from entering the clean side of the air intake system during primary filter servicing
• Designed to plug rapidly if contamination bypasses the primary filter, alerting operators to potential issues

Donaldson recommends replacing safety filters with every third primary filter change unless there has been a primary filter failure. Compatible with numerous OEM applications including Caterpillar, Baldwin PA2574, Fleetguard AF4554M, and Fram CA6327SY.
