Filter Test Stand Calibration Services

IFTS USA is pleased to offer annual calibration services for its filter test stands in the US.  This includes calibrating flow, temperature and pressure sensors using NIST-traceable equipment, typically to within 1% accuracy.  Utilizing its highly accurate equipment, IFTS field engineers can perform the calibration on site, with minimal downtime.  After performing the service, IFTS supplies a Certificate of Calibration, documenting the equipment used, their traceability and the calibration results.

The service results in a fine tuned, highly accurate test bench, one that meets quality requirements and boosts overall confidence with test results. A calibrated filter test system ensures the reliability and repeatability of development testing, allowing manufacturers and end users alike to validate the performance of filters that protect their mission critical equipment and systems.

IFTS Presents Technical Session at AFS Spring Conference

For the first time in four years, the American Filtration & Separations Society’s (AFS) Conference was held in Minneapolis, Minnesota from May 6-9. The annual spring conference focused on filtration and separations in global markets.

Christophe Peuchot, Managing Director of IFTS in Agen, France and President of IFTS, Inc. USA, Jerry Lynch, presented the technical session, “How to Compare Performances of Domestic Pools and Spas Filters.” The presentation discussed how the absence of any technical data on the performances of filters to consumers and pool fitters is impacting the European pool filter manufacturers economy. IFTS, as a cooperative research center, has developed a new test method which is currently being studied by CEN TC 402.

Lynch was also a member of a panel where he discussed separation technology, electro-mechanical design & build solutions for products, pilots and test systems for IFTS’ sister company, Sigma Design.

The annual AFS Fall Conference will be held in October in Cincinnati, Ohio and will be focused around the topic of Innovations in Fiber Media.

Meet IFTS’ Global Team:

For the last 15 years, Nicolas has been working in an international and multidisciplinary environment to qualify liquid filters.

As manager of LMC and CEEF, he is in daily contact with international professionals ranging from nuclear, aeronautic and chemical industries to help them develop and select their best-suited filters and to control the cleanliness of their components. To qualify their filters and their components, he uses the most accurate counting particle technologies from 0.1 to 1000 µm.

Nicolas has developed worldwide-recognized expertise in filtration and has become an advisor on filter technology to ISO committees.

Filter Cold Test Chamber


A top and side view of the chamber.

After repeated requests from aircraft manufacturing firms, airplane engineers and aerospace filter manufacturers, IFTS has invested and developed a highly accurate cryogenic filter test chamber.

The complete test system and associated equipment, is housed in a fully insulated cold chamber which allows in depth filter tests at temperatures as low as -40°C, flow rates up to 50 gpm (200 L/min), and at differential pressures up to 90 psid (~6 bar). The flexibility of the system design allows us to perform various custom test configurations. This might include the filter and all its associated components tested within the cold chamber at a constant low temperature, or another popular method is where all equipment is held outside the chamber at ambient temperatures and only the test filter is inside at the low test temperature.

As an example; a recent test program consisted of monitoring the clogging and physical behavior of kerosene filters in the presence of trace water in kerosene at -45°C and a flow rate of 50 L/min. Water was injected upstream the circulation pump to create an emulsified test fluid and ∆P was continuously recorded until the end of test value was reached. The results provided an in depth and unique view of these challenging conditions.

Validation Criteria of an APC Calibration Suspension Preparation Loop

Globally there is a need for highly accurate particle counting. This is especially true in the filtration and separation industry. An ISO expert group took on the responsibility to draft the new specification for the improved calibration fluid, SRM2806b, which will be used to calibrate optical particle counters worldwide.  IFTS accepted the development challenge and used its expertise in particle counting and cleanliness control to develop a new world class fluid process and production system to produce the new calibration fluid.

 6b Secondary Calibration Fluid

SRM2806b Secondary Calibration Fluid

The initial challenge was to produce four hundred, 400mL bottles with an ISO suspension of silica powders in a standard mineral oil and to guarantee that the particle size distribution is replicated in each and every bottle.

With this new validated equipment, IFTS can now guarantee online particle stability within 1 % >4 µm(c) and 5 % >40 µm(c) and larger.

Our new equipment will allow IFTS to supply the world market with the most repeatable secondary calibration suspensions ever prepared according to ISO 11171.

NIST is currently validating all the bottles in their labs in Maryland.

IFTS Organizes Centrifugal Technical Session at AFS Conference and Teaches Liquid Testing at INDA

Pascal Ginisty, Research Manager at IFTS in Agen, France presents at the AFS Fall Conference in Philadelphia, PA.

IFTS, Inc. USA’s President Gerard J. Lynch, P.E. was a speaker at the American Filtration & Separations Society’s (AFS) Fall Conference and the Association of the Nonwoven Fabrics Industry’s (INDA) Filtration International Conference & Exposition. Both conferences were held in Philadelphia, Pennsylvania.

At the AFS Fall Conference, IFTS organized a 4-paper session titled “Centrifugal Separation Technology – Lab to Commercialization.” One of the presenters was Pascal Ginisty of IFTS France who gave an overview of centrifugal separation test methods and techniques. Lynch presented a paper about an axial centrifuge-testing program with the US Maritime Administration.
