New LPG Filter Removes Potentially Harmful Particulate Matter

Donaldson FiltersAlliance AutoGas, the leading company in converting medium and heavy-duty fleets to propane autogas, has aligned with Donaldson Company to release a new line of clean, LPG filters that remove potentially harmful particulate matter and heavy ends from propane systems. The filters were designed for the propane industry and are currently available through propane equipment distributors nationwide.

Founded in 1915, Donaldson has a history of developing innovative filtration solutions, including the invention of the first engine air filter more than 100 years ago. This standard of innovation has made Donaldson a good fit with Alliance AutoGas, whose own innovative history has brought the industry the only Plug and Play Engineered System for propane, the Staubli Quick-Connect Refueling Nozzle, and the Propane Evacuation Pump among others.

While it’s common for gasoline and diesel fuels to be filtered multiple times as it’s transported to an end-user, propane has historically not been filtered. As propane has gained popularity as a transportation fuel, called autogas, consistent fuel quality has become a greater need for fleet customers. Two new filters, brought to market by Alliance AutoGas and Donaldson, have been specifically designed to eliminate potential fuel contamination issues with autogas fuel dispenser systems. A highly efficient primary LPG particulate filter was developed to remove 99% of harmful particulates 0.5 micron and larger. Additionally, through Donaldson’s international leadership in carbon filtration products, a secondary absorbent carbon filter specifically engineered to remove heavy ends, without removing the odorant from propane, was designed.

Industry experts were consulted during the research and development process, resulting in a design that exceeds the highest industry safety standards. The filter housings are made from a high phosphorus nickel-plated steel, meeting current NFPA 58 ( requirements for Pressure Containing Metal Parts, unlike other currently available autogas filtration products.

Fleets demanding maximum performance from their propane vehicles benefit from the implementation of filtration products through reduced vehicle downtime and maintenance. Whether your fleet is focused on particulates or heavy ends, the dual filter design can be tailored to a fleet’s specific need. The filters can be sold and installed separately or together, to ensure a customized solution.
