The PetroClear 40505W-AD 5-Micron Dispenser Filter is engineered to help fuel-site operators protect today’s sophisticated engine components. The 40505W-AD dispenser filter captures particulates as small as five microns and prevents them from entering and damaging the fuel-injection system. The filter will also sense when elevated levels of water are present in the fuel and alerts the fuel-site operator through slow-flow dispenser operation that the fuel contains potentially damaging amounts of water that can cause bio contamination and poor lubricity.
