Isola Naida is equipped with a Parker-Racor 1000FH Turbine Series fuel filter and water separator.
The Racor 1000FH is installed in behind the companionway ladder and operates independently of the engine’s diesel fuel supply system. Fuel can be supplied to the filter from either the keel tank or the auxiliary tank and returned to either the keel tank or the auxiliary tank, or, provided to the Autoturm Diesel Heater.
Equipment Profile
Manufacturer: Parker Racor
Series: Turbine
Model: 1000FH
Type: Primary diesel fuel filter and water separator
Fuel: Diesel
Function
The Racor 1000FH performs two primary functions:
- Fuel filtration removing particulate contamination from the diesel fuel.
- Water separation, separating free water from the fuel before it reaches the engine.
Water and other contaminants can cause damage to diesel fuel injection components and contribute to poor engine performance.
The transparent filter bowl allows accumulated water and contamination to be visually inspected and drained as required.
Maintenance
The Racor should be inspected periodically for:
- Water accumulation in the bowl
- Sediment or other contamination
- Fuel leakage
- Damaged seals or O-rings
- Condition of the filter element
- Condition of fuel hoses and connections
Water or contamination should be drained from the separator as required. The filter element should be replaced according to the engine maintenance schedule, fuel condition, and operating experience.
Whenever the filter is opened or the filter element is replaced, the fuel system should be properly primed and checked for leaks before operating the engine.
Filter Options
The Racor 1000FH uses replaceable Racor 2020-series filter elements. Several elements are available for the 1000FH, with different filtration ratings to suit different applications.
Common elements include the 2020N30, 2020N10, and 2020N2, providing nominal filtration ratings of approximately 30, 10, and 2 microns, respectively. The lower the micron rating, the finer the filtration provided by the element.
Filter selection involves a balance between filtration and fuel-flow requirements. A finer element provides greater particulate filtration but may impose greater restriction as the element becomes loaded with contamination.
