Common Questions
What micron rating should I use?
For diesel dispensing into modern common-rail engines, 10µm or finer is recommended. For older engines, 25µm is adequate. For bulk transfer into storage tanks, 25µm pre-filtration followed by 10µm at the dispensing point provides two-stage protection.
How often should I change filter elements?
Change elements when the differential pressure indicator shows restriction, or at least annually if the indicator hasn't triggered. In contaminated fuel environments, elements may need changing every 3–6 months. Always stock spare elements.
Do I need water removal as well as particulate?
Yes, if you're storing diesel for more than a few weeks. Water enters tanks through condensation, vent breathers, and delivery. Free water promotes microbial growth (diesel bug) and causes injector corrosion. A water-separation filter on the dispensing side prevents water reaching engines.
What's a differential pressure indicator?
A gauge or switch that measures the pressure difference across the filter element. As the element loads with contaminant, pressure difference increases. When it reaches the element's rated limit, the indicator signals that the element needs changing. Available in mechanical (visual) and electrical (switch output) versions.
