Parker 3B-8312N-3A1 Oil Water Filter Separator 300 Cfm

Product Description

The PARKER 3B-8312N-3A1 is an oil water filter separator designed to remove dust, oil, particulate, and water contamination from compressed air systems. It handles up to 300 cubic feet per minute (CFM) of airflow and is rated for a maximum working pressure of 250 psi, making it suited for demanding industrial and commercial compressed air applications. The unit features an automatic drain, which continuously evacuates collected liquids without manual intervention. At 30 inches tall and 30 inches wide and weighing 45 pounds, this is a full-sized separator intended for permanent installation by qualified technicians in facilities with moderate to high compressed air demand.

This separator is applied in compressed air distribution systems where contamination control is critical — including manufacturing facilities, industrial plants, and commercial service environments. It is used upstream of air tools, pneumatic controls, and production equipment to protect components from moisture and oil carryover. The 1-1/2 inch NPT end connections allow direct integration into standard piping headers. It is well suited for both new installations and retrofit applications where an existing manual drain unit is being replaced with an auto-drain configuration.

Key Features

• 300 CFM rated airflow capacity for high-demand compressed air systems
• 250 psi maximum working pressure for robust industrial service
• Automatic drain eliminates manual liquid removal and reduces maintenance intervals
• 1-1/2 inch NPT end connections for direct inline piping integration
• Handles dust, oil, particulate, and water — broad-spectrum contamination removal
• Maximum operating temperature of 130 degrees F

Compatibility

Designed as an OEM-style inline filter separator for compressed air piping systems using 1-1/2 inch NPT connections with flow requirements up to 300 CFM and operating pressures up to 250 psi.

Installation Notes

Installation should be performed by a qualified technician or pipefitter familiar with compressed air system plumbing and applicable codes. Depressurize and lock out the compressed air supply completely before beginning installation or servicing the unit. Use thread sealant rated for compressed air service on all NPT connections and verify joint integrity before returning the system to pressure. Orient the unit per manufacturer direction to ensure proper automatic drain function and confirm the drain outlet is routed to an appropriate collection point per local environmental regulations.
