Description

High-Output Tow-Behind Rotary Screw Industrial Air System

The ELGi D185T4F 185 CFM Portable Rotary Screw Air Compressor is a heavy-duty, tow-behind system engineered for high-demand industrial pneumatic applications. Powered by a 49 HP turbo intercooled Kohler KDI 1903 TCR diesel engine, this portable unit delivers a consistent 100 PSI output without the complexity of DPF or DEF exhaust filtration. Featuring a direct-drive configuration, a 23-gallon fuel tank, and a protective steel enclosure, this compressor solves the problem of high maintenance downtime during continuous job site sandblasting, structural demolition, and high-volume pneumatic tool operations.

Best Used For:

  • Industrial Sandblasting Operations: Providing continuous, high-volume air output for abrasive media blasting and surface preparation.
  • Pneumatic Road Construction: Powering heavy-duty breakers, rock drills, and line-striping equipment simultaneously via dual 3/4-inch NPT outlets.
  • Fleet Utility Operations: Supporting remote oil field, structural demolition, and utility service crews needing mobile tow-behind compressed air.

Key Performance & Safety Features

  • Kohler KDI Diesel Technology: Advanced 49 HP turbo intercooled 3-cylinder engine delivers exceptional torque and fuel economy.
  • Maintenance-Free Tier 4 Compliance: Achieves rigid EPA Tier 4 Final requirements completely without a complex DPF or DEF system.
  • Curb-Side Control Panel: Side-mounted electronic gauges keep operators safely away from street traffic during system monitoring.
  • Intelligent Mechanical Protection: Specialized start/stop programming prevents cold start damage and air-end oil blowback.
  • Minimum Pressure Check Valve: Heavy-duty check loop isolates line feedback and completely prevents oil back-feeding into the system.
