Parker 8312N-1A1-BX Oil Water Filter Separator 155 Cfm

Product Description

The PARKER 8312N-1A1-BX is a compressed air oil-water filter and separator designed for industrial and commercial pneumatic systems. It removes dust, oil aerosols, particulate, and liquid water from compressed air lines, protecting downstream equipment and maintaining air quality. Rated for 155 CFM airflow and a maximum working pressure of 250 psi, this unit handles demanding system loads. The automatic drain eliminates the need for manual bowl draining during operation. At 17 inches tall and 5 inches wide, it fits inline applications where space allows a dedicated separation stage. Licensed mechanical or industrial contractors typically handle installation in high-demand compressed air systems.

This filter-separator is suited for industrial facilities, manufacturing environments, HVAC mechanical rooms, and other settings where compressed air quality directly affects equipment performance. It is applied at point-of-entry or point-of-use in compressed air distribution systems handling dust, oil contamination, and condensate. The 1-1/2 inch NPT threaded connections make it compatible with standard iron pipe or schedule-40 fittings common in industrial plumbing and compressed air headers.

Key Features

• 155 CFM rated airflow capacity for medium-to-large compressed air systems
• 250 psi maximum working pressure supports high-pressure pneumatic lines
• Automatic drain type eliminates manual servicing intervals for condensate removal
• 1-1/2 inch NPT end connections for direct inline pipe installation
• Removes dust, oil aerosols, particulate, and liquid water in a single stage
• Maximum operating temperature of 130 degrees F suitable for typical indoor mechanical environments

Compatibility

Designed as an OEM-style inline replacement or new-installation filter-separator for compressed air systems using 1-1/2 inch NPT piping with airflow requirements up to 155 CFM and pressures up to 250 psi.

Installation Notes

Installation should be performed by a qualified mechanic or pipefitter familiar with compressed air distribution systems. Depressurize and lock out the air supply before installing or servicing this unit. Use thread sealant rated for compressed air on all NPT connections and verify flow direction matches the arrow or inlet marking on the separator body. Confirm that downstream pressure ratings and system operating temperature remain within the 250 psi and 130 degrees F limits of this unit.
