Norgren F74H-4AD-QD0 Coalescing Filter 0.01 Micron

Product Description

The NORGREN F74H-4AD-QD0 is a coalescing filter designed to remove oil aerosols, water aerosols, and fine particulate contamination from compressed air lines. Rated at 0.01 micron filtration efficiency, it targets sub-micron contaminants that standard particulate filters cannot capture. The body features an aluminum bowl with a manual drain for routine condensate removal. With a maximum operating pressure of 250 psi and a 1/2 inch port size, this filter is suited for industrial compressed air systems where clean, dry air is critical to downstream equipment performance. Installation and servicing are typically handled by industrial maintenance technicians or pipefitters.

This coalescing filter is appropriate for use in compressed air distribution systems in both light industrial and heavy industrial environments. Typical applications include instrument air supply lines, pneumatic control circuits, spray finishing systems, and air preparation assemblies where oil carryover or fine aerosol contamination would damage tooling, actuators, or sensitive instrumentation. The 1/2 inch port size accommodates mid-range flow demands common in workshop and plant floor installations. The manual drain requires periodic attention during routine maintenance intervals to prevent liquid re-entrainment into the downstream air supply.

Key Features

• 0.01 micron filtration rating removes sub-micron oil and water aerosols from compressed air
• 250 psi maximum operating pressure for compatibility with standard industrial compressed air systems
• 1/2 inch port size suits mid-range compressed air distribution lines
• Aluminum bowl construction provides durability with reduced weight compared to steel alternatives
• Manual drain allows controlled condensate removal during scheduled maintenance
• Compact footprint at 3.15 inches wide and 11.4 inches high for installation in tight panel or line spaces

Compatibility

Designed as an OEM-style coalescing filter for 1/2 inch compressed air lines requiring sub-micron aerosol filtration at pressures up to 250 psi.

Installation Notes

Installation is typically performed by a licensed pipefitter or qualified industrial maintenance technician. Depressurize and lock out the compressed air supply completely before removing or installing any filter element or bowl. Verify port thread type and confirm line pressure does not exceed the 250 psi rated maximum before commissioning. Drain condensate regularly via the manual drain to maintain filtration efficiency and prevent liquid carryover to downstream equipment.
