MANN-FILTER LB 13 145/20 Air-Oil Separator — for Commercial Vehicle Compressors

Increased oil carryover in the compressed air system, reduced compressor efficiency, pressure drops, or unusual noise from the compressor — these are common signs that your air-oil separator needs replacement. The separator removes oil from the compressed air, ensuring clean air output, protecting downstream equipment, and extending the service life of your compressor. A clogged or degraded separator can cause poor performance, increased oil consumption, and potential damage to pneumatic tools and accessories.

This is a premium compressed air-oil separation filter (MANN-FILTER LB 13 145/20) designed for commercial vehicle and industrial compressors. It features high-quality separation media that ensures high separation efficiency and low residual oil content, minimizing oil loss and reducing energy consumption over the service life. The filter is a spin-on StarBox design, ready to install. This is a trusted aftermarket alternative to the OEM part.

 

When to Replace

• Increased oil carryover into the compressed air system
• Reduced compressor efficiency or performance
• Pressure drops across the separator
• Unusual noise from the compressor
• Visible oil contamination downstream of the separator
• The separator has been in service for the recommended interval (typically 4,000–8,000 hours depending on operating pressure)
