Why Reliable Generator Fuel Filtration Matters
For data centers, hospitals, and financial institutions, generator failure during a grid outage is a business-critical event.
Why Fuel Quality is so Important for Generators
Vehicles cycle fuel continuously – generators don’t. A standby unit may sit for weeks or months between runs, and the fuel degrades the entire time.
Three compounding threats to standby fuel quality include:
- Sediment and water accumulation – Stagnant fuel allows particulates and water to settle at the tank bottom, directly in the fuel pickup path
- Moisture and algae growth – Humidity drives water incursion and microbial contamination in stored fuel
- Modern fuel additives – Lubricity agents used in the fuel pipeline can leave fatty acid byproducts that compound filtration challenges
