Description
Stauff Heavy Fuel Filter Elements – SFK-439 Series: Safety Filtration for Injection Systems
The SFK-439 series filter elements represent Stauff’s engineered solution for Heavy Fuel applications, specifically designed to ensure maximum fluid cleanliness during the most critical phases of the operating process. These components perform the vital function of separating contaminant particles from the fluid flow, acting as the final filtration stage immediately before direct injection into the engine room or combustor.
Design Features and Materials
The SFK-439 series is built to withstand demanding operating conditions typical of heavy fuel supply systems.
- Filter Media: The element uses stainless steel mesh. As specified in Stauff’s general material guidelines for hydraulic applications, stainless steel wire meshes provide excellent chemical and thermal resistance, along with low flow resistance due to their large-pore screening surface.
- Structure: The end caps are made of stainless steel, providing the entire assembly with the structural robustness required to maintain integrity even under severe operating stress.
Dimensional Specifications and Variants
Dimensional accuracy is essential to ensure proper installation and sealing within dedicated housings.
- Dimensions: Each element in the SFK-439 series has a fixed length of 439 mm (17.28 in) and an outer diameter of 48 mm (1.89 in).
- Filtration Rating: The series is available in two specific filtration grades to meet different system cleanliness requirements: 6 µm or 10 µm.
Applications
The primary application of these elements is particle separation in Heavy Fuel circuits. Their strategic position within the system—as the final barrier before injection—is critical for protecting sensitive engine room and combustor components from damage caused by solid contaminants, ensuring operational continuity and efficient combustion.
