Cummins Filtration first in industry to utilize Beta ratio

Cummins Filtration has begun using the scientific measurement of Beta to most accurately benchmark and measure the filtration capability of the many technologically-advanced filtration media that make use of the company's patented nano-fiber technology.

A wholly owned business unit of Cummins, Cummins Filtration (www.cumminsfiltration.com) is the world's leading designer and manufacturer of filtration and chemical technology products for all engine-powered equipment.

The Beta rating is the most accurate means of measurement for predicting the effectiveness of a filtration media's actual service performance out in the "real world," according to officials at Cummins Filtration.

The most commonly used method to demonstrate this scientific nomenclature and how it applies to measuring the effectiveness of Cummins Filtration products is in Beta Ratio.

In the following example, the Beta Ratio compares the number of particles entering a filter media (the "dirty" upstream side) to those exiting the filter medium (the "clean" downstream side):

- A Beta Ratio of 2 = 100,000 upstream particles/50,000 downstream particles = 50 percent efficiency.

- A Beta Ratio of 10 = 100,000 upstream particles/10,000 downstream particles = 90 percent efficiency.

- A Beta Ratio of 100 = 100,000 upstream particles/1,000 downstream particles = 99 percent efficiency.

- A Beta Ratio of 1,000 = 100,000 upstream particles/100 downstream particles = 99.9 percent efficiency.

By making use of the acute Beta (?) measurement when testing filtration media performance, Cummins Filtration customers are ensured a superior standard for protection against harmful contaminants within an engine's fluids that could lead to additional costs in the form of needless engine wear, repairs or a decrease in fuel economy, said the officials.

Cummins Filtration's new fuel filtration media can trap contaminants as small as 4 microns - particles smaller than red blood cells in the human body (typically 6 to 8 microns in width), they noted.

Modern diesel engines equipped with high pressure common rail fuel systems (HPCR) that operate at pressures exceeding a whopping 29,000 psi require an unprecedented degree of fuel cleanliness.

The World Wide Fuel Charter (WWFC) has determined that a full 50 percent of the fuel dispensed at retail fuel pumps around the globe does not meet the necessary cleanliness of ISO standards recommended by ISO 18/16/13 (ISO 4406 Contamination Code).

Cummins Filtration's extensive research on the matter has determined that, while bulk fuel filtration is desirable to aid in helping to control fuel contamination levels, there is no substitute for effective on-engine fuel filtration.

While many fuel filter manufacturers test their products under controlled conditions in the laboratory, officials said Cummins Filtration develops its filtration media/filtration products through rigorous testing in the field, subjecting products not only to heavy dust and dirt exposure, but also to heavy vibration as equipment is operated in the "real world."

The result is an "exceptional level" of engine and fuel injector protection from water (free and emulsified), organic (waxes, residual from refining fuel) and inorganic (dirt and wear metals within the system) contaminants in your tractor-trailer, power generator or skid steer whether operated on-highway or off, added the officials.
