SHAFT 4J2088 - Caterpillar

Natural gas engines require fuel that is clean, dry and at the acceptable pressure for engine operation. Filters for natural gas engines are critical to supply the engine with the clean and dry fuel and are appropriately sized for the gas pressure required for engine operation.Gas fuel filters are no less important than air filters in diesel engines to protect gas engines from dirt and debris. A proper gas fuel filter removes impurities that can damage internal components of the engine.For many gas engines, fuel filters are a provision of the design for the application. These devices are included in the normal maintenance of the plant. Hence, Cat does not include a standard gas fuel filter as a part of each gas engine. However, gas fuel filters are available from your Cat dealer.Cat natural gas filters have the following characteristics:
Specially treated borosilicate glass microfibers that actively repel oil and water
A positive o-ring seal to prevent entry of debris and particulate matter especially in high soot operating conditions that tend to plug normal filters
Chemical resistant end caps built to withstand challenging operating environmentsNote: Use a gas fuel filter that is designed to capture a minimum of 99 percent of the particles that are 1 micron in diameter.Consult your Cat dealer for Cat natural gas fuel filters and about the requirements for filtering your fuel.For information on the engine oil filters for gas engines, refer to this Special Publication, "Fluid Filters and Engine Oil Filters".
