40 Micron Pro Filter with -12 ORB Ports Blue Finish

40 Micron Pro Filter with -12 ORB Ports — Blue Finish

Engineered for demanding fuel systems, this 40 micron Pro Filter from Aeroflow combines rugged construction with easy maintenance to safeguard high-performance builds. Its compact 5-1/2" long, 2" diameter body fits tight spaces while delivering reliable filtration for both pre-pump and post-pump stages. The blue anodized exterior not only looks striking but stands up to the rigors of under-hood use.

What makes it stand out

• High-performance filtration: 40 micron element designed to capture fine particulates without throttling flow, ideal for 200–2700+ HP applications.
• Durable, repairable design: CNC-machined 6061-T6 aluminum body with a stainless-steel, reusable, and washable filter element for long-term service.
• Magnetic protection: Internal magnet helps trap metallic contaminants for added protection of the fuel system.
• Explosive compatibility: Safe to use with exotic fuels such as E85 and methanol, expanding versatility across performance builds.
• Precise sealing: O-rings provide positive sealing in high-pressure environments, with easy replacement options available.

Installation, use, and maintenance

The stainless-steel filter element is reusable and washable to minimize maintenance costs over time. This filter is best suited for both pre-pump and post-pump filtration to balance protection with flow. Mounting brackets are available separately to fit in-car or under-car installations. Body sizes and configurations vary—choose the appropriate form factor to suit your space constraints. When filtration efficiency declines or the element requires replacement, swap in AF59-2444 40 Micron element or choose from the other micron options listed above. Keep spare O-rings and springs on hand for quick service to minimize downtime. The internal magnet provides ongoing particulate capture, helping extend the life of pumps and injectors.
