## Beta rating filtration

Beta Ratio. Filtration beta ratios are calculated by dividing the upstream ( unfiltered) particle count for a given micron rating by the downstream (filtered) particle 9 Feb 2009 Capture efficiency is expressed as filtration ratio (commonly called beta ratio) — the relationship between the number of particles greater than 21 Nov 2002 Normally, users come across beta ratios of 100, 1,000 and 10,000 for cartridge filters. Keep in mind, a beta ratio of 1,000 (β1000 or b1000) is 10 What is Beta Ratio? The Beta Ratio is a filter rating on the performance of a filter to trap particles of a set micron size, or larger. Bx is the Beta Ratio for a filter for 14 Feb 2020 Absolute-rated filter cartridges offer maximum dirt holding capacity coupled with micron retention ratings to 0.5 at beta 5000 or 99.98 percent 8 Oct 2014 Particle micron size must be specified when describing beta ratio, and conversely , no filter micron rating is worthwhile without knowing the beta

## The Beta rating comes from the Multi-pass Method for evaluating performance of a fine filter element (ISO 16889:1999). Whether you do it yourself or send samples to a lab, fluid sampling should be performed upstream and downstream of the filter to get an accurate effectiveness of the filter.

3 Jan 2017 Beta ratio is often used when expressing filter efficiency for a given particulate size. This, in simple terms, is the number of particles in the 29 Nov 2016 Similarly, the size and quantity of particles downstream of the filter are also measured. The beta ratio is defined as the particle count upstream A Beta Ratio may be given for a filter as B10. = 50. (Depicted in this way on many filters). This simply means that the Beta Ratio for 10 micron equals a ration of 50 of the media used inside an element by its 'Beta ratio'. ISO 16889 (International Standard) lists eight common Beta ratios used to report filter efficiency, these are 1 Dec 2014 The number of particles counted upstream is divided by the number of particles downstream, which provides the beta ratio for the filter element In essence, the Beta ratio is an indicator of how well a filter controls a specifically sized particulate. For example, if one out of every two particles in a fluid pass LFEX is a range of low pressure filter for protection of sensitive components in glass fibre PS filter beta rated elements according to ISO 16889 multipass test

### 1 Dec 2014 The number of particles counted upstream is divided by the number of particles downstream, which provides the beta ratio for the filter element

All types of filter cartridges are available in different micron ratings and dirt load capacity, large surface area at absolute rating of beta 5000 (99.98% removal). Product Range Overview HyPro Filtration. • Dynamic Filter Filter elements + filter assemblies manufacture. Primary Dynamic Filter Efficiency : Beta Ratio (β) Micron rating, 0.5 – 50 micron. Beta ratio, 5000 (99.98% effective removal). Filter media, Pleated glass fibre, supported by all polypropylene construction. It is important to remember that a micron rating without an associated beta ratio or efficiency does not fully describe the performance of a filter. A filter that has a filter, head or housing assembly. • Filter performance curves will either list media numbers or beta ratings (see circled areas on chart above). These labels 2 Feb 2015 The most common rating for liquid filters is the Beta Ratio. Beta ratio testing is a universally accepted test method that yields readily comparable

Cross-Reference + Product Guide. It's easy to find the right filter for your equipment using the Baldwin Filters' eCatalog. Use the Cross-Reference to find crosses to Still, absolute ratings are better for representing the effectiveness of a filter over nominal ratings. Figure 1. Beta Rating. The best and most commonly used rating in industry is the beta rating. The beta rating comes from the Multipass Method for Evaluating Filtration Performance of a Fine Filter Element (ISO 16889:1999). Your shirt sleeve may well have a Beta ratio higher than 2000 on particles the size of marbles. The same sleeve may have a Beta ratio of less than 2 on particles the size of talcum powder. Beta ratings can be used to explain the efficiency of filtration for all fluids, oil, diesel, petrol etc; it’s simply a measurement. In the world of filters and filtration, Beta Ratio plays an important role. There have been complaints of breakdowns in hydraulic systems mainly due to the improper Beta Ratio and high levels of substantial contamination. Beta Ratio brings in the effectiveness of the hydraulic system. It aids in the prevention of failure of the filtration process. The life expectancy depends upon the water consumed. Beta stability is the measure of how well a filter element is able to maintain its measured Beta Ratio at pressure drops beyond the limits of the normal operating range. For example, beta 200 stability = 210 psid, means that the Beta Ratio for the rated micron size will not drop below beta 200 until it reaches 210 psid across the element. The nominal rating also represents an efficiency figure or degree of filtration. A nominal rating example is “95% of 10 micron” – where the filter prevents 95% of all 10 micron and larger particles from passing through. However, the nominal rating method is generally discouraged. Beta Ratio refers to the efficiency in which a given filter element removes particles of a given size. The Beta Ratio is calculated using the ISO multi-pass test standard 16889:1999. The test involves adding particles of a known size to the test fluid until the fluid reaches a saturation point,

## 29 Nov 2016 Similarly, the size and quantity of particles downstream of the filter are also measured. The beta ratio is defined as the particle count upstream

2 Nov 2017 For example, if a filter element is rated for 5 micron (also written as 5 µm), the Beta Ratio applies to that size particle alone. The Beta Ratio itself is 3 Jan 2017 Beta ratio is often used when expressing filter efficiency for a given particulate size. This, in simple terms, is the number of particles in the 29 Nov 2016 Similarly, the size and quantity of particles downstream of the filter are also measured. The beta ratio is defined as the particle count upstream A Beta Ratio may be given for a filter as B10. = 50. (Depicted in this way on many filters). This simply means that the Beta Ratio for 10 micron equals a ration of 50

Depth filtration is closer to the perfect filter as it conforms closer to filter performance criteria. The effective repeatedly micron beta rating is substantially higher than Cross-Reference + Product Guide. It's easy to find the right filter for your equipment using the Baldwin Filters' eCatalog.
