  We concluded in our last article on Beta Factor . In this article, we will talk more about BETA Factor for buying new filters. What is the Beta Ratio? The beta ratio refers to the efficiency in which a given filter element removes the particle of a given size. The Beta Ratio is calculated using the ISO multi-pass test standard 16889:1999. How is it measured? The test involves adding particles of a known size to the test fluid until the fluid reaches a saturation point and then bringing the filter online to remove particles in one pass through the element. It is important to consider that the beta ratio is valid for a particular size of the particle. For Example for a 5-micron filter, how many particles are above 5-micron mark in upstream of the filter and how many are downstream is measured. And then by using the below formula, the Beta Ratio is calculated. Each Beta factor corresponds to an efficiency of the filter, the same can be matched as per the below chart. Get your filter ch

  Have you ever thought when you raise a requirement for a particular filter let’s say a 10-micron filter you get a range of prices some being ridiculously low and some being higher than most, and all claim to give the best 10-micron filter? We get tricked at this point and without looking at differences we think that the only differentiator is the profit margin and procure the filter with the least price. For filter check contact - +91 7030901266. Let’s try to understand the real reason for the price difference. There are two types of filter ratings: 1.  Absolute: Filter Rating meaning 99.9% of the particles larger than a specified micron rating will be trapped on or within the filter. 2.  Nominal: Filter Rating indicating the approximate size particle, the majority of which will not pass through the filter. It is generally interpreted as meaning that 85% of the particles of the size equal to the nominal filter rating will be retained by the filter. So, a vendor quoting for an Absol
