3034508WFC – Donaldson Filters FAA-PMA Engine Oil Filter Element for P&WC Engines
Available now on the Airparts.aero Marketplace.
Overview
The Donaldson 3034508WFC is a high-performance, FAA-PMA certified engine oil filter element assembly designed for the world's most proven and popular turboprop engines, the Pratt & Whitney Canada (P&WC) PT6A and PW100 series. This flight-critical component serves as the primary line of defense for the engine's lubrication system, capturing and removing microscopic contaminants that can cause catastrophic damage to high-speed bearings, gears, and other close-tolerance components. This filter is an approved, airworthy replacement for the P&WC OEM part number 3034508.
Engineered with Donaldson's advanced Synteq™ synthetic microglass media, this filter provides superior filtration efficiency, high dirt-holding capacity, and low pressure drop compared to traditional cellulose filters. The assembly includes an integrated, calibrated bypass valve as a critical safety feature to ensure continued oil flow in the event of a completely clogged filter. As a fully FAA-PMA approved part, the 3034508WFC has undergone rigorous testing to demonstrate that its performance is equal to or better than the original OEM part, making it the premier choice for operators seeking the highest level of engine protection and value.
Key Features
FAA-PMA Certified: Fully certified by the FAA as an airworthy replacement for P&WC P/N 3034508, guaranteeing fit, form, and function.
Advanced Synteq™ Synthetic Media: Utilizes Donaldson's proprietary synthetic microglass fibers to create a depth-loading media that captures finer particles and holds more contaminants than conventional filters.
Superior Filtration Efficiency: Offers a high Beta ratio, effectively removing the microscopic metallic and carbon particles that cause the most damage to turbine engine bearings and gears.
High Dirt-Holding Capacity: The depth-loading media design provides a long service life and maintains low pressure drop, even as the filter captures contaminants.
Integrated Bypass Valve: A critical safety feature, the calibrated bypass valve ensures the engine is never starved of oil, even under extreme contamination scenarios.
Robust Construction: Features corrosion-resistant steel end caps and center tube for maximum structural integrity and resistance to high-pressure oil flow.

Why Choose 3034508WFC?
The oil filter is the kidney of your multi-million-dollar turbine engine. The Donaldson 3034508WFC is a premium, FAA-PMA certified product that provides a direct path to superior engine protection. The FAA-PMA process is a rigorous certification that legally confirms this filter is an equivalent or superior alternative to the original. Choosing this filter provides the confidence of Donaldson's world-leading filtration technology and the assurance of full airworthiness and compliance. Using any non-certified filter is not only illegal but also introduces an unacceptable risk of engine failure due to either insufficient filtration or an improperly calibrated bypass valve leading to oil starvation.
The superior performance of the 3034508WFC filter is rooted in the tribology of its Synteq™ synthetic microglass media. Unlike traditional cellulose media which has irregular, paper-like fibers and relies on surface-loading filtration, Synteq™ media is a complex three-dimensional matrix of precisely controlled, cylindrical synthetic fibers of varying diameters. This creates a graded pore structure that enables "depth loading." As oil flows through the media, larger particles are trapped on the outer layers, while progressively smaller particles are captured deeper within the matrix through the mechanisms of direct interception, inertial impaction, and diffusion. This process is quantified by the filter's Beta Ratio (βx), an industry standard for measuring efficiency at a given particle size (x, in microns). A high Beta Ratio ensures the capture of particles smaller than the critical dynamic clearances in the engine's high-speed rolling element bearings, preventing the chain reaction of abrasive wear that leads to spalling and eventual failure.
Note: The 3034508WFC is a flight-critical, disposable component. It must be installed by a certified A&P/IA mechanic during a scheduled oil and filter change, in strict accordance with the Pratt & Whitney Canada engine maintenance manual. The new seal must be lubricated with clean engine oil, and the filter canister must be torqued to the specified value. The used filter element must be cut open and the media inspected for metal particles as a primary means of engine health monitoring.
