There are many instances of VmI products functioning 10 or more years. When our customers review critical component equipment, it is important to remember the more cycles, wear, and exposure, the higher the probability of reduced function or imminent failure. VmI suggests each site have a preventative maintenance / risk reduction program that incorporates each site’s ecological sensitivity, historical information, equipment age, maintenance history and other operational risk management considerations. Our customers should consider a replacement schedule based on information provided to us by testers. Site specific conditions including particulates in the fuel, exposure to acids, water or other oxidizing agents in the fuel, and other site specific conditions may cause premature substandard performance or equipment failure.
