Our filter media is backed by ISO 16889 multi-pass testing and other ISO/SAE test protocols, and the filter is produced in an ISO Certified manufacturing facility. An ISO Certified manufacturing facility is all about quality control, consistency, responsibility, and being true to the design. If you’re not ISO 9001 Certified, your approach to quality and consistency is all talk.
This Fram FD121G03BV hydraulic filter replacement element is beta-rated.
Optimized microglass media is used for fine filtration, just like the Fram FD121G03BVhydraulic filter that you’re replacing. Our Microglass uses the optimal amount of media and pleats in the element to ensure high dirt-holding capacity. The correct number and design of pleats in the element will give you the lowest initial pressure drop, meaning the filter will take longer to reach its change-out pressure drop, usually 25 PSID.
- Beta 3 = 200, Beta 4.5 = 1000, equivalent to efficiency of 99.9%,
This filter is compatible with the following fluids, but pressure drop will vary depending on viscosity and temperature:
- Hydraulic Fluid and Machining Fluids, Water Glycols and Coolants
- Diesel, Gasoline and other fuels, Lubricating Oils, Synthetic Lubricants, and Process Fluids
- Turbine and Compressor Lube Oils … And many more fluids
Our Fram FD121G03BV hydraulic filter is indicated as a replacement and is not manufactured by or affiliated with the OEM or Brand listed. Part numbers and names are used for cross reference only. Element may vary from the image displayed on the left.
