Norgren F74G-4AN-AD3. Compressed Air Filter 140 Cfm

Product Description

The NORGREN F74G-4AN-AD3. is a compressed air filter designed to remove contaminants from pneumatic system supply lines. It features a 1/2 inch port, an aluminum bowl, and an automatic drain mechanism that expels accumulated moisture and particulate without manual intervention. Rated at 140 cubic feet per minute (CFM), this filter suits moderate to high-flow compressed air applications in industrial and commercial environments. It is typically installed by pipefitters, millwrights, or maintenance technicians as part of a filter-regulator-lubricator (FRL) assembly or as a standalone inline filter upstream of sensitive pneumatic equipment.

This filter is suited for compressed air distribution systems where consistent air quality is critical to tool and equipment performance. The automatic drain eliminates the need for scheduled manual draining, making it well suited for production environments or remote installations where routine service access is limited. The 1/2 inch port size accommodates standard NPT or equivalent pneumatic line connections commonly found in light industrial, manufacturing, and process control applications.

Key Features

• 140 CFM flow capacity supports moderate to high-demand pneumatic systems
• Automatic drain continuously expels collected moisture and debris without manual service
• 1/2 inch port size fits standard pneumatic supply line configurations
• Aluminum bowl construction offers durability with reduced weight compared to steel alternatives
• Inline design integrates into existing FRL assemblies or standalone filter stations

Compatibility

Designed as an OEM-style replacement or direct-fit compressed air filter for pneumatic systems requiring a 1/2 inch port inline filter with automatic drain functionality.

Installation Notes

Installation is typically performed by a qualified pipefitter or pneumatic systems technician. Depressurize and lock out the compressed air supply line before removing any existing filter or making new connections. Verify port thread type and size before installation to ensure a leak-free fit. Follow applicable OSHA compressed air safety standards and local pneumatic system codes during service.
