Carrier 06NA660028 Filter & O-Ring

As a veteran tech, you know that maintaining the integrity of the oil circuit in a screw compressor is non-negotiable for system longevity. The Carrier 06NA660028 Filter & O-Ring is the high-performance internal oil filter replacement engineered specifically for 06N and 06NW series compressors. This kit is the direct replacement for 8TB0320, ensuring zero-clearance compatibility and high-efficiency filtration of metal particulates and carbon deposits that threaten bearing surfaces. By utilizing a 1-13/16 inch outer diameter primary element, it maintains the precise micron rating required to prevent orifice clogging in the economizer and motor cooling lines.

The included precision-molded compressor O-ring provides a critical leak-proof seal between the filter cartridge and the internal housing, preventing bypass and maintaining essential differential pressure. Whether you are performing a seasonal teardown or addressing high acid levels, using a genuine Carrier HVAC filter ensures the lubrication system meets OEM flow specifications. This 06NA660028 oil filter kit is a vital component for protecting commercial chiller compressors from premature mechanical wear and ensuring clean oil circulation in high-load industrial environments.

• OEM Compatibility: Serves as the official 8TB0320 replacement filter for a perfect fit in 06NA and 06NW compressor housings.
• Contaminant Control: Effectively traps abrasive particles and sludge, protecting high-tolerance internal rotors and bearings.
• System Integrity: Includes a matched O-ring to ensure a tight compression seal and high-pressure performance.
• Enhanced Performance: Optimizes heat transfer and reduces internal friction by maintaining the purity of the compressor lubricating oil.

Is the 06NA660028 a direct swap for the 8TB0320?
Yes, this is the current production Carrier internal oil filter designed to replace the legacy 8TB0320 part number without any modifications to the filter cavity.

When should the internal oil filter and O-ring be replaced?
Standard protocol for HVAC preventative maintenance suggests replacement during any major service, oil change, or when a high pressure drop is detected across the oil circuit.

Does this kit include everything needed for the filter change?
The kit contains the 06NA660028 filter element and the specific O-ring required for the housing cover. It is recommended to have 06N-specific grease on hand for the O-ring seating.
