About Safran Filtration Systems



Safran Filtration Systems (ex-Sofrance), a Safran company, offers recognized expertise in filtration systems and components for air, fuel, oil and other fluids and gases.


Safran Filtration Systems is a supplier to a number of industries, including aerospace, defense and manufacturing, addressing all filtration requirements from initial design to production and support.



  • Particle filtration
  • Phase separation
  • Controls and decontamination


Safran Filtration Systems develops optimized solutions to purify fluids and protect systems and facilities.

Operating across the aerospace, defense and manufacturing industries, we make four main filter families:

  • air and gases
  • water
  • fuels
  • oil and hydraulic fluids

Each family has its own specific characteristics, depending on the type of fluids to be treated, the filtration level, and the technology used to eliminate these contaminants.

The company "Filtres français" was created in 1941, and was renamed Sofrance four years later, then Safran Filtration Systems in 2016.


Until the late fifties, Sofrance growth was mainly driven by the automotive market and the iron and steel industry. The company entered the aerospace market in 1958, when it began working with Sud Aviation, a French state-owned aircraft manufacturer, on the new Caravelle commercial jet. This was only the beginning, because in the 1960s Sofrance was chosen for major new aircraft such as the Mirage fighter and Concorde supersonic transport.

The Labinal group acquired Sofrance in 1973 to establish a dedicated aerospace branch, accelerating its development in this sector. Sofrance subsequently gained a role in other major new programs, such as the Airbus A320 and the CFM56 turbofan engine. In 2000 Labinal sold its aerospace branch to Snecma, which wanted to grow its aircraft equipment business. Snecma then merged with Sagem in 2005 to create Safran, and Sofrance became part of Messier-Bugatti-Dowty (renamed Safran Landing Systems in 2016). As part of Safran, Sofrance was chosen for the Airbus A380 and A350, as well as the Boeing 787.


Building on this rich history, combined with a policy of constant significant investments, Safran Filtration Systems has become one of the world leaders in filtration systems for all types of aircraft (fixed and rotary wing, drones), and covering all fluids (fuel, oil and air).



All components used in Safran Filtration Systems filters are designed, manufactured and assembled in our own production plant.


Our R&D and production capabilities count on highly skilled staff (trained in the jobs specific to this business), using state-of-the-art production machinery and demonstrating expertise in all steps of the process.

All of our employees become multi-skilled, based on advanced training and apprenticeship programs for these high-tech processes. Throughout their careers, our staff learn about different workstations, as well as the many sophisticated techniques used to produce a Safran Filtration Systems filter. On their own or encouraged by management, they discover a wide range of exciting jobs, including the assembly of electronic sensors, bath solution proportions, high-temp brazing, 5-axis milling and crimping. At Safran Filtration Systems, we invest up to 4% of payroll in training.

Sofrance's production plant comprises four dedicated workshops:

  • Machining (precision mechanical parts)
  • Crimping
  • Assembly
  • Testing


Each of our employees is capable of handling all or part of the production process. Our production runs range from 5 to 1,000 pieces. Cleanliness is imperative at each stage of the process. From electro-deburring to tribo-finishing, not to mention the surface treatment workshop, Safran Filtration Systems does everything possible to guarantee cleanliness.

This combination of human and technical resources provides cutting-edge support for the development and production of new products. Our completely integrated production facilities mean a flexible solution for all customers. Our Supply Chain Management entity monitors the performance of our production system, which is checked each step of the way by our Quality Assurance teams. The main objectives of this approach are to ensure on-time delivery, while keeping costs under control and steadily reducing production cycles.


Product qualification


To ensure that our filters fully meet specs, Safran Filtration Systems carries out a wide range of tests and inspections, reflecting our state-of-the-art qualification process. This approach calls on demanding standards and outstanding test systems. It plays an indispensable role in delivering a response keyed to increasingly demanding technical requirements.

By investing in research, testing and human resources, Safran Filtration Systems upholds its position as a leading expert in filtration. For instance, we make significant annual investments in our fleet of test benches and measurement systems.

Safran's Laboratory and Test department, seven persons strong, is capable of carrying out all conventional filtration tests (efficiency, load loss, filtration capacity) on different types of fluids (air, oil, fuel), as well as all specific tests (performance at different temperatures, load cycling, operation under rain and saline fog conditions for air filters, etc.) In addition we deploy different test benches to characterize our equipment at different temperatures (fatigue, rotational flexion, endurance, etc.).

Drawing on our proven skills in fluid analysis and particle counting, Sofrance can characterize and qualify all components (clogging indicators, complete filters, bypass filters, etc.), or even carry out specific tests on request..
