Filtration - Clean Fuel Reduces Downtime

With the increase in diesel injection pressures on engines and the sophistication of plant machinery, higher fuel and fluid cleanliness levels are a requirement in today’s equipment.

We have partnered with Donaldson Filtration to provide bulk filtration systems that can reduce downtime, save on costly component replacement, and improve fuel economy. In short, Donaldson reduces your total cost of ownership.

Below are a sample of some of the Donaldson products we offer, however; if you want to know more or gain a quote don't hesitate to contact us and speak to one of our filtration specialists.

ISO Code & Beta Ratio

ISO Cleanliness Code

The ISO Cleanliness Code was developed for measuring fluid cleanliness and is widely used for determining particle counts in lubricants. It specifies the size of particles measured and the method for coding the level of contamination. The ISO 4406 standard utilizes a three number system to classify system cleanliness — example: 19/16/13. The first number means there are between 2,500 and 5,000 particles >4 μm, between 320 and 640 particles >6 μm and between 40 and 80 particles >14 μm. The second represents particles greater than 6μm and the third represents those greater than 14μm

Filter Beta Ratios

The Beta Ratio equals the ratio of the number of particles of a minimum given size upstream of the filter to the number of particles of the same size and larger found downstream. Simply put, the higher the Beta Ratio the higher the Capture Efficiency of the filter.

T.R.A.P.™ Breathers

Regenerative TRAP Breathers strip moisture from incoming air, allowing only dry air to enter the tank.  During the filling of the tank exhausting air picks up the moisture collected and "blows it back out", thereby regenerating the filter for longer element life.
