Particle Cleanliness

Filtrex and Filtrex Automotive are turnkey systems designed to analyze particulate contamination for automotive, pharmaceuticals, and aeronautics industries.


Typical applications

Analysis of oil products

Controlling particle contamination in oil products, such as fuels, hydraulic fluids and lubricants, is critical for all of the system components.

Cleaning of mechanical parts

Numerous technologies require the use of fluids and parts free from particle contamination. Component cleanliness is particularly important in the automotive and aerospace industries and for instrumentation in general.

Cleanliness of pharmaceutical parts

Particulate contamination control for pharmaceutical parts: stoppers, bottles, packaging, plastic films…
