Parker 3B-8208N-3A1 Oil Water Filter Separator 77 Cfm

Product Description

The PARKER 3B-8208N-3A1 is a compressed-air oil-water filter and separator designed to remove dust, oil, particulate, and water contamination from compressed-air systems. It handles up to 77 CFM at a maximum working pressure of 250 psi, making it suitable for industrial and commercial compressed-air applications where clean, dry air is critical to downstream equipment performance. The unit features an automatic drain that expels collected liquids without manual intervention, reducing maintenance demands during continuous operation. Licensed HVAC technicians, pipefitters, and industrial mechanics typically specify this separator as a primary or secondary filtration stage in compressed-air distribution systems.

This filter-separator is applied in settings where compressed-air quality must meet process or equipment requirements — including manufacturing facilities, spray finishing lines, pneumatic tool systems, and mechanical equipment rooms. The NPT end connections allow direct integration into standard threaded compressed-air piping. With a maximum operating temperature of 130 degrees F, it suits most ambient and compressed-air line conditions found in light industrial and commercial environments. The automatic drain function is particularly useful in high-humidity or high-cycle installations where manual drain schedules are impractical.

Key Features

• 77 CFM flow capacity for medium to high-volume compressed-air systems
• 250 psi maximum working pressure for standard industrial service
• Automatic drain eliminates manual liquid removal and reduces maintenance intervals
• NPT end connections integrate directly with standard threaded pipe fittings
• Removes dust, oil, particulate, and water contamination in a single stage
• Rated to 130 degrees F maximum operating temperature

Compatibility

Designed as an OEM-style replacement or direct-install separator for compressed-air distribution systems requiring NPT-connected filtration up to 77 CFM and 250 psi.

Installation Notes

Installation should be performed by a qualified pipefitter, millwright, or licensed mechanical contractor familiar with compressed-air distribution systems. Depressurize and lock out the air supply line completely before removing any existing separator or installing this unit. NPT threads require appropriate thread sealant rated for compressed-air service. Verify that system flow and pressure ratings do not exceed the 77 CFM and 250 psi limits of this separator under any operating condition.
