The Industrial Gas Filtration and Generation Division of Parker Hannifin Corporation has announced the release of its next-generation R Series hydrogen refueling filters, engineered specifically for compressed gaseous hydrogen (CGH₂) used in fuel dispensing applications.
These filters, RL0700, RM0700, and RH1000, are the first in Parker’s dedicated line of hydrogen-specific filtration solutions. They are designed to meet the evolving needs of the hydrogen economy and offer critical protection at the point of dispensing.
With hydrogen fuel cells powering the transition to cleaner transportation and decarbonized mobility, maintaining ultra-clean hydrogen is essential for equipment performance and vehicle safety. The R Series filters utilize advanced, high-efficiency media to remove particulate contamination, aerosols, and moisture that can compromise fuel cell operation.
Each model is designed in an in-line configuration featuring a durable 316 stainless steel head and bowl assembly. This material selection minimizes the risk of hydrogen embrittlement—a critical consideration for safety and longevity in high-pressure hydrogen systems.
“We designed the R Series hydrogen refueling filters with multiple inlet/outlet port options and flow rate choices for maximum flexibility,” said John D’Antonio, Engineering Supervisor at Parker’s Industrial Gas Filtration & Generation Division. “They deliver clean hydrogen to the vehicle that meets SAE J2719 cleanliness protocols.”

R-Series Filter Weights & Dimensions
Fuel quality specifications are defined by both ISO14687 and SAE J2719 for fuel cell vehicle applications. Per these standards, contaminants are Impurities that adversely affect the components within the fuel cell system, the fuel cell power system, or the hydrogen storage system, and particulates are specifically defined as Solids or liquids, such as oil mist, that can be entrained somewhere in the production, delivery, storage, or transfer of the hydrogen fuel to a fuel cell system.
