1. Main Technical Parameters

-*Filtration Accuracy**: Standard 70 μm (radial flow granular activated carbon structure; custom grades also available: 1–70 μm glass fiber, 5–40 μm filter paper, 3–400 μm metal mesh, etc.)

-*Rated Flow Rate**: 6–9100 L/min (adjustable according to viscosity and pressure differential)

-*Operating Pressure**: ≤450 bar (instantaneous peak)

-*Operating Temperature**: -30 ℃～+120 ℃

-*Filter Media Structure**: Outer 70 μm polyethylene shell + granular activated carbon (GAC) interlayer, polypropylene end caps; optional all-PP, glass fiber, or stainless steel skeleton

-*Bypass Valve Opening Pressure Differential**: ≈0.2 MPa (2 bar)

-*Sealing Type**: Dual O-ring (nitrile/EPDM optional), spin-on, compatible with 10″ Big-Blue filter housing

 2. Testing Standards:

ISO 2941 (burst resistance), ISO 2942 (structural integrity), ISO 2943 (material compatibility), ISO 3723 (end load), ISO 3724 (fatigue), ISO 3968 (pressure differential-flow), ISO 4572/16889 (multiple pass filtration ratio)

 3. Typical Marine Applications:

- Central cooling water for main/auxiliary engines, pre-filtration for seawater desalination in water makers

- Removal of particulate matter from drinking water, tank cleaning water, ballast water, and bilge water

- Post-filtration for fuel-water separators, protection of freshwater circulation in power plants and platforms

 4. Interchangeability and Substitution: 155141-43 (Pentek RFC-BB) and 0803004873 are completely identical in size, sealing and function, and can be interchanged 1:1; there are also RFC-20BB, RFC-20 and other alternatives with the same housing. When selecting, you only need to check the connection size, filtration accuracy and whether activated carbon is required.
