897830-1 - Honeywell Fuel Filter Element

897830-1 – Honeywell Fuel Filter Element

Available now through the AirParts Aero marketplace.

Overview Section

The Honeywell 897830-1 is a high-performance, precision-engineered Fuel Filter Element designed specifically for the auxiliary power units (APU) and turbine engines manufactured by Honeywell Aerospace. This filter is a critical component of the fuel control system, tasked with removing microscopic contaminants from the fuel stream before it enters the high-pressure fuel pump and fuel nozzles.

As a genuine Honeywell OEM part, the 897830-1 is constructed to withstand the high-flow rates and varying pressure differentials found in turbine environments. Its multi-layered media is optimized for capturing silt, rust, and microbiological growth, ensuring the precise fuel-metering components of the engine remain free from debris that could cause erratic engine behavior or flameouts.

Key Features Section

• Advanced Pleated Media: Features high-density pleats that provide a massive filtration surface area within a compact cylinder, allowing for long service intervals.

• High-Pressure Durability: Engineered with a reinforced internal core to prevent media collapse during cold-start scenarios when fuel viscosity is high.

• Precise Micron Rating: Designed to trap particulates at the sub-micron level, protecting sensitive fuel injectors and governor assemblies.

• Fuel Compatibility: Fully compatible with Jet A, Jet A-1, JP-5, and JP-8 fuels, as well as common fuel additives like Prist (FSII).

• Vibration Resistant: Specifically designed for the high-frequency vibration environments of turbine engine accessory gearboxes.

• Integrated Seals: Typically supplied with high-grade fluorocarbon (Viton) O-rings or gaskets to ensure a leak-proof seal within the filter housing.

Technical Specifications Section

Aircraft Compatibility Section

The 897830-1 is a standard maintenance item for many turbine-powered aircraft found in the AirParts Aero inventory:

• Business Jets: Extensively used in the APU systems of Cessna Citation, Hawker, and Learjet aircraft.

• Turboprops: Found in the fuel systems of Pilatus PC-6 and Beechcraft King Air models equipped with Honeywell TPE engines.

• Regional Transports: Utilized in various commuter aircraft utilizing Honeywell 36-series auxiliary power units.

Technical Applications & Safety

In a turbine engine, fuel acts not only as a source of energy but also as a coolant and lubricant for the fuel pump. If the 897830-1 becomes saturated or bypassed, particulates can enter the FCU (Fuel Control Unit). This often leads to "sticky" power levers, hung starts, or a catastrophic failure of the high-pressure pump.

Safety Warning: Never attempt to clean a 897830-1 element. Turbine filters utilize depth-loading media that cannot be cleared by back-flushing. Always replace the element at the intervals specified in the Honeywell Engine Maintenance Manual or when the "Fuel Filter Bypass" light illuminates on the cockpit annunciator panel.

Technical Engineering Insight

The engineering value of the Honeywell 897830-1 lies in its Differential Pressure Management. Turbine fuel systems operate at significantly higher pressures than piston systems. The 897830-1 is designed with a specific "bypass relief" threshold. If the filter becomes completely clogged, a bypass valve in the housing opens to ensure the engine continues to receive fuel; however, this fuel is unfiltered.

The 897830-1 media is treated with an anti-static agent to prevent the buildup of static electricity as fuel flows through the tight fibers at high velocity. This prevents internal arcing which could theoretically damage the filter media. By choosing the genuine Honeywell part through AirParts Aero, you ensure the metallurgical integrity of the end caps and the chemical stability of the adhesives used to bond the media, preventing "media migration" into the fuel nozzles.

Installation & Maintenance Addendum

1. O-Ring Lubrication: Lubricate new housing O-rings with a light film of clean Jet-A or a specified petroleum jelly to prevent "rolling" or pinching during installation.

2. Bowl Cleaning: Before installing the 897830-1, inspect the bottom of the filter bowl for water or "brown slime" (fungal growth). If found, the fuel system may require biocidal treatment.

3. Venting: After replacement, the fuel system must be primed and vented to remove air pockets that could cause an engine surge or flameout during the first start.

Product Overview

A replaceable device designed to remove solid particles from fluids ranging in density from heavy liquids to gases. The removal of particles is accomplished by porous material (metallic or non-metallic), stacked disks, wound wire, or the like, constructed so the fluid can flow through the device while the solid particles are retained. It may be designed to fit into a filter, fluid (or similar cavity), or it may have an integral outer casing and mounting facilities and be designed to connect directly to an engine, compressor, or the like. The degree of removal of particles must be nominally rated at less than 50 microns or absolutely rated at less than 75 microns. Excludes filter element, air conditioning. See also strainer element, sediment.
