The PARKER 3PU25-235 X 1 is a cellulose replacement filter element rated at 3 microns, designed for use in compressed air or gas filtration systems that require periodic media replacement. This element fits Parker Finite H-Series filter housings and functions by capturing particulate contamination down to 3 microns to protect downstream equipment, tooling, and pneumatic components. At 2.5 inches in height and 23.5 inches in width, it is a direct-fit replacement that restores housing performance to rated flow capacity. Installation is performed by HVAC technicians, industrial maintenance mechanics, and compressed air system specialists as part of routine preventive maintenance.
This filter element is suited for industrial and commercial compressed air systems where consistent filtration is required to maintain equipment reliability. With a rated flow of 1,035 standard cubic feet per minute (SCFM), it is appropriate for moderate to high-flow applications. The cellulose filter media makes it a cost-effective choice for general-duty filtration where synthetic media is not required. It is packaged and sold as an individual unit, making it straightforward to order as a single replacement when servicing a housing in the field.
Designed for use with Parker Finite H-Series filter housings, as specified by the manufacturer.
Filter element replacement should be performed by a qualified technician familiar with compressed air system maintenance. Before servicing, depressurize and isolate the filter housing completely to prevent injury from stored pressure. Follow the housing manufacturer's service instructions for element removal and insertion to ensure proper seating and sealing. Dispose of the used element in accordance with local regulations, particularly if the system handles oil-laden air.
