Description

185 CFM Tow-Behind Diesel Air Power

The ELGi D185T4F air compressor is a direct-drive, tow-behind rotary screw compressor delivering 185 CFM at 100 PSI. It is powered by a Kohler KDI 1903 TCR Tier 4 Final diesel engine and is built for construction, maintenance, utility and blasting applications that need a full 185 CFM air supply.

An available dual-pressure configuration is listed at 150 CFM at 150 PSI, expanding the operating range for compatible equipment. The model was previously sold under the Rotair brand in North America.

ELGi D185T4F Features

• 185 CFM at 100 PSI: Standard output for common towable-compressor applications.
• Optional dual pressure: Listed output of 150 CFM at 150 PSI when the option is fitted.
• Direct-drive rotary screw airend: Provides continuous compressed air for professional use.
• Kohler Tier 4 Final diesel engine: Uses a DPF-free emissions approach in the listed configuration.
• Intelligent start/stop system: Helps prevent cold starting and blowback.
• All-steel enclosure and running gear: Protects components during transport and jobsite use.
• Accessible service layout: Curbside controls, service points and a standard toolbox support field operation.

Applications

• Dry ice blasting and abrasive blasting
• Construction, road maintenance and demolition tools
• Irrigation and utility service
• Cable and fiber installation
• Industrial maintenance and remote pneumatic equipment

Using the D185T4F for Dry Ice Blasting

A 185 CFM compressor can support many professional dry ice blasting systems, but compatibility depends on the machine’s required airflow at the selected pressure. The optional 150 PSI mode provides higher pressure with reduced airflow and should be matched to the blaster’s operating curve rather than treated as 185 CFM at 150 PSI.

Dry ice blasting requires moisture control. Depending on ambient conditions and compressor options, add an aftercooler, water separator, coalescing filter and dryer sized for the full airflow. Hose length, fittings and treatment components all reduce delivered pressure.

Review our dry ice blasting compressor and air-treatment guide before finalizing the system.
