C-Tzu replacement air filter set for Donaldson FPG05 — Outer & Inner (2-Pack, OEM fit)

C-Tzu 2-set replacement includes one outer air filter and one inner filter engineered to fit Donaldson FPG05 air cleaners, replacing part numbers 6672467 and 6672468.

If you need a dependable pair of replacement elements for Donaldson FPG05 style air cleaners, this C-Tzu package supplies both the outer prefilter and inner primary filter in one purchase. Each element is shaped to match the original equipment dimensions so it installs easily into compatible housings and restores the two-stage filtration the system was designed for. The set is intended for use in applications where keeping abrasive dust and particulates out of the engine intake is a priority.

How do these filters fit Donaldson FPG05 units?

Each C-Tzu element is manufactured to the same general form factor as the Donaldson originals so they seat correctly in FPG05 housings. Proper fit keeps the factory sealing surfaces engaged and prevents bypass of unfiltered air.

• Direct replacement for Donaldson FPG05-compatible models.
• Designed to align with original filter grooves and seals.
• Outer and inner elements sold together for complete renewal.

What protection does the outer and inner combination provide?

The two-stage arrangement separates large contaminants from finer particles, extending service life and reducing contaminant load on the primary element. The outer prefilter captures coarser debris while the inner filter provides finer particle retention.

• Outer element blocks large dust, sand, and debris first.
• Inner element traps smaller particulate before the engine intake.
• Combined arrangement reduces stress on the primary filter and housing.

How easy is installation and maintenance?

Installation is straightforward: remove the old elements, check the housing seal, and seat the new outer and inner filters in their respective positions. The set is intended to let routine replacement be completed quickly with minimal tools.

• Swap both elements at recommended service intervals for best performance.
• Forms an effective seal with existing filter housing to prevent leaks.
• Anti-vibration fit helps maintain contact under heavy equipment use.

What materials and performance features are included?

The elements use multi-layer media and precision-formed end caps to provide consistent filtration and structural support. The components are designed to hold up under dusty conditions while maintaining airflow characteristics suitable for the intended applications.

• High-quality filter media captures a range of particle sizes.
• Reinforced ends and seals preserve integrity during operation.
• Compatible with machines that require tight anti-vibration sealing.

Who is this for: technicians, fleet managers, and equipment owners who operate machines equipped with Donaldson FPG05-style air cleaners and need a matched pair of replacement elements. This C-Tzu set is useful for scheduled maintenance, field service, or when restoring filtration following heavy dust exposure. Verify model compatibility with your equipment manual and the original part numbers (6672467, 6672468) before purchase to ensure correct fit.
