GENERAL INFORMATION

Figure 3. Doors Closed

TRANSPORT

This compressor is trailer-mounted for easy transport by

a towing vehicle. Trailer is equipped with an adjustable

4-hole channel that accepts either a ball or pintle coupler.

All tail stop, turn signal and side marker lamps are D.O.T.-

approved.

ENGINE

This compressor is powered by a 4-cylinder, 4-cycle water

cooled, direct injection, turbocharged, air-cooled EGR Isuzu
4LE2T

diesel engine. This engine is designed to meet every

performance requirement for the air compressor. Reference

Table 2 for engine specifications.

ELECTRIC GOVERNOR SYSTEM

The electric governor system controls the RPMs of the engine.

When the engine demand increases or decreases, the

governor system regulates the frequency variation to ±.25%.
