The package emphasizes compatibility with machines starting serial numbers above 415201 and notes that older serial ranges use a different kit. Quality control is highlighted by technicians and engineers to help maintain high-performance output and extend compressor lifespan, while also reducing routine maintenance costs.
BANGTE LB962/2 Oil Separator Cartridge
The LB962/2 oil separator cartridge is listed with multiple part numbers (6221347800, 2205406508, 4930658131, 9056292, 410151022, R7432, 7211960000). It is designed to prevent oil buildup, protect against detonation, and minimize oil loss, contributing to reduced maintenance and more consistent compressor performance. The product highlights a compact dimensional profile (H 212 mm, A 93 mm, B 62 mm, C 71 mm) and emphasizes high-quality filtration suitable for screw air compressors.
54749247 Air Oil Separator Filter
GXFCY’s 54749247 filter is pitched as a compatible replacement for several UP series units (UP5, UP6, UP6-15 through UP6-30). The listing focuses on ease of replacement and compatibility with existing part numbers such as 54749247, 22436331, A10525274, 22354633, 24900342, 48958235, 1202834300, 46652735, and 1626832100. The product promises a straightforward replacement experience to help maintain oil separation and overall system efficiency.
NEIKO 30253A Water and Oil Separator
NEIKO’s 30253A model covers water and oil separation for a 1/4″ NPT inlet/outlet, designed for 150 PSI. It aims to protect pneumatic tools and extend tool life by stopping moisture and oil from entering air lines. The unit ensures clean air delivery by separating oil and capturing moisture, thus supporting better tool performance and reliability. It emphasizes maintaining maximum tool performance under varying pressures.
CAtArt 3/4″ NPT Air Dryer With Separator
This 3/4″ NPT industrial air dryer module includes a three-stage filtration system and a built-in desiccant dryer. It targets high-pressure environments up to 240 PSI and claims to remove a significant portion of moisture and contaminants. The second-stage filter features a visual indicator, and the desiccant beads turn color to signal when maintenance is needed. This unit is positioned as a comprehensive solution for producing clean, dry air in demanding industrial settings.
Buying Guide: Key Purchase Considerations
- Compatibility: Verify model compatibility with your compressor brand and series. Some kits target specific serial ranges or model families, while others offer broader application.
- Included Components: Check whether a kit includes the oil separator, oil filter, and air filter, or if you need to source components separately.
- Filtration Stages: Multi-stage separators and dryers can improve air quality, but may require more maintenance; balance performance with maintenance practicality.
- Pressure Range: Ensure the product supports your system’s operating pressure (PSI). Some options are optimized for higher pressures up to 240 PSI.
- Maintenance Indicators: Features like visual indicators for filter replacement help prevent performance dips and tool wear.
- Durability and Materials: Look for heavy‑duty housings and corrosion‑resistant components, especially in humid workshop environments.
- Cost vs. Lifespan: While initial cost matters, consider long-term maintenance savings from reduced oil carryover and cleaner air.
- Warranty and Support: Favor options backed by technical support and reliable warranty coverage for critical industrial use.
