FPAS-M

Filter Particulate Analysis System – M Introduction

The FPAS series of image analysis based particulate counting equipments are being offered to fulfil the requirements of automotive industry for measurement of cleanliness levels of the manufactured components.

The presence of particles residue from the manufacturing and assembly process will cause a substantial increase in wear rates of the system during initial run up and early life and may even cause catastrophic failures. Hence in order to achieve reliable performance of components & systems, it is necessary to have control over the amount of particles introduced during the build phase.

The System

The system consists of

High resolution Optics
Precision engineered Stand
Filter sample holder
4 position x,y stage with magnetic stoppers
Latest high configuration computer
Advanced pro priority software for particle counting & classification as per industry standards

Methodology

The automotive component received after the manufacturing & cleaning process are taken to the lab where they are sprayed with a solvent fluid (IPA) using a high pressure spray gun. The solvent fluid is collected in a pan and the same is passed through a membrane filter. The residual particles are collected on the filter. The filter is dried in an oven. The dried filter is held in a special filter holder. The entire filter surface is scanned & imaged by the High resolution camera and optics

System Specifications

Particles Size	≤ 100μ
Time taken per filter	3-4 minutes Apporax
Filter Holder	For holding standard dia 47 filters
Computer	Latest Configuration computer with 19” monitor
Software	User friendly software for Particulate Analysis

Particulate analysis software

The advanced particle analysis software detects, counts and measures all the particles present on the surface of the filter. The detected particles are automatically classified into metallic, non metallic and fiber types. Each type of particles are further divided into different size classes ranging from 100 to 1000 µm & above.
