Original MANN-FILTER Compressed air-oil separation LB 11 102/2 – For utility vehicles

Product Overview

The MANN‑FILTER Compressed Air‑Oil Separation LB 11 102/2 is a high‑performance separator designed to remove oil and water contaminants from compressed air systems used in utility vehicles. It delivers clean, dry air that protects downstream equipment such as pneumatic tools, hydraulic pumps, and control valves.

Core Functionality

This unit operates by separating liquid droplets and fine particles from the airstream through a combination of centrifugal action and filtration media. The separated oil is collected in an internal reservoir for easy disposal or reuse, while the cleaned air exits through a dedicated outlet.

Key Technical Specifications

• Model: LB 11 102/2
• Operating Pressure Range: 0–10 bar (up to 150 psi)
• Air Flow Capacity: Up to 200 m³/h at 8 bar
• Separation Efficiency: ≥99.9 % oil removal, ≤5 ppm water content
• Operating Temperature: –20 °C to +60 °C
• Dimensions (L×W×H): 250 mm × 120 mm × 140 mm
• Weight: 4.5 kg
• Material Construction: Stainless steel housing with polypropylene filter cartridge
• Connection Type: ISO 5167 standard fittings (1/2” and 3/4”)

Design Features

The separator incorporates several design elements that enhance reliability and ease of use:

• Centrifugal Separator Core: A rotating impeller creates a high‑velocity air stream, causing oil droplets to be flung outward onto collection plates.
• Dual‑Stage Filtration: After centrifugal separation, the air passes through a fine filter that captures remaining micro‑droplets and particulate matter.
• Oil Reservoir with Level Indicator: A transparent tank allows operators to monitor oil accumulation without disassembly.
• Self‑Cleaning Valve: An integrated valve permits reverse flow for periodic cleaning of the filter cartridge.
• Modular Assembly: All components can be detached and reassembled quickly, minimizing downtime during maintenance.

Installation Guidelines

Proper installation is critical to achieving optimal performance. Follow these steps:

1. Position the separator on a stable surface within the vehicle’s air distribution panel.
2. Connect the inlet pipe to the compressed air supply using ISO fittings, ensuring all connections are torque‑tightened to prevent leaks.
3. Attach the outlet pipe to the downstream equipment or air reservoir.
4. Verify that the oil reservoir is oriented correctly so gravity can assist in oil drainage.
5. Perform a pressure test at operating conditions before commencing normal operation.

Maintenance Procedures

Regular maintenance extends service life and maintains separation efficiency:

• Oil Drainage: Empty the reservoir every 200 hours of operation or when the level indicator reaches the maximum mark.
• Filter Replacement: Inspect the filter cartridge monthly; replace it if visual inspection shows clogging or after 500 operating hours.
• Cleaning: Use a soft brush to remove accumulated oil from internal surfaces. Avoid abrasive tools that could damage the polypropylene filter.
• Inspection: Check for cracks, corrosion, and wear on the housing and fittings during routine checks.

Performance Benefits

The LB 11 102/2 delivers several advantages to utility vehicle operators:

• Extended Equipment Life: By eliminating oil contamination, pneumatic tools and hydraulic components experience reduced wear.
• Improved Safety: Clean air reduces the risk of fire or explosion in environments where flammable gases may be present.
• Operational Efficiency: Lower maintenance intervals translate to higher vehicle uptime.
• Environmental Compliance: Proper oil disposal prevents environmental contamination and meets regulatory standards.

Applications in Utility Vehicles

This separator is ideal for a wide range of utility vehicles, including:

• Dump trucks and loaders with integrated pneumatic tool systems.
• Construction equipment such as jackhammers and impact wrenches that rely on compressed air.
• Maintenance vans equipped with hydraulic pumps and air compressors.
• Industrial transport vehicles requiring clean air for safety-critical operations.

Compatibility and Integration

The LB 11 102/2 is compatible with most standard compressed air systems used in commercial fleets. Its ISO fittings allow seamless integration with existing piping, while the modular design ensures that it can be retrofitted into older vehicle models without extensive modifications.

Conclusion

With its robust construction, high separation efficiency, and user‑friendly maintenance features, the MANN‑FILTER Compressed Air‑Oil Separation LB 11 102/2 stands out as a reliable solution for protecting compressed air systems in utility vehicles. By ensuring that downstream equipment receives clean, dry air, this separator contributes to longer component life, safer operation, and overall fleet efficiency.
