Norgren F74H-4AD-AD0 Coalescing Filter 1/2 Inch Port

Product Description

The NORGREN F74H-4AD-AD0 is a coalescing filter designed to remove oil aerosols, fine particulates, and liquid water from compressed air lines. It features a 1/2-inch port, an aluminum bowl construction, and an automatic drain for continuous moisture removal without manual intervention. Rated at 0.01 micron filtration efficiency, it targets submicron contaminants that standard particulate filters pass. The unit handles up to 250 psi, making it suitable for most industrial and commercial compressed air systems. Licensed pneumatic technicians and mechanical contractors install this type of filter as part of air treatment trains ahead of sensitive instrumentation, spray equipment, or precision pneumatic actuators.

The F74H-4AD-AD0 fits into compressed air treatment assemblies in light industrial, commercial, and process-control environments. It is typically positioned downstream of a primary particulate filter and upstream of a pressure regulator or lubricator. Applications include pneumatic tool lines, spray finishing booths, automated assembly equipment, and any compressed air circuit where oil carryover from upstream compressors must be controlled. The automatic drain keeps the bowl clear during continuous-duty operation, reducing maintenance intervals in high-condensate environments.

Key Features

• 0.01 micron filtration rating captures fine oil aerosols and submicron particulates
• 250 psi maximum working pressure suits most industrial compressed air systems
• Automatic drain removes accumulated liquid without manual service
• Aluminum bowl construction offers corrosion resistance and light weight
• 1/2-inch port size fits standard compressed air line configurations

Compatibility

Designed as an OEM-style replacement or direct installation coalescing filter for 1/2-inch compressed air treatment systems operating up to 250 psi.

Installation Notes

Installation should be performed by a qualified pneumatic or mechanical technician. Depressurize and lock out the compressed air supply completely before removing any existing filter or connecting the new unit. Ensure flow direction matches the arrow marked on the filter body. Follow applicable OSHA compressed air safety guidelines and local mechanical codes during installation and when servicing the automatic drain assembly.
