direct cooling air in and out of the compressor package, to prevent recirculation (e.g., hot cooling air
entering the fresh air inlet). The package is designed to operate at ambient temperatures ranging from
40
°
F to 113
°
F (at up to 1000 meter elevation). Contact Gardner Denver for package operation at
conditions exceeding the stipulated values.
A typical ventilation arrangement is shown in Figure 2-1.

When selecting the compressor package location, be aware that its noise level may increase above its
advertised free-field condition by reflections from nearby objects (e.g., walls, machinery, etc) or by noise
from nearby machinery.
Air-Cooled Units
- A combination oil/air cooler is supplied as standard equipment on all air-cooled
packages. The heat exchangers require sufficient cooling air flow to operate efficiently – please refer to
Section 6, Fig 6-1 of this manual for detailed instructions on the operation and maintenance of air-cooled
heat exchangers, including minimum heat exchanger cooling and enclosure ventilation requirements.
Cooling air for the heat exchangers, main motors, and electronics box is drawn in at the intake grill end of
the enclosure and is exhausted through a roof vent. Refer to Package Illustrations on Figure 1-2 and
Figure 1-3, pages 9 and 10, for hardware details.
Do not block flow of air entering or exiting the enclosure - allow a minimum of 3-1/2 feet (1.1 m) clearance
to the nearest obstruction all around and on top.
Water-Cooled Units
– Separate brazed plate-type coolers for air and oil services are supplied on water-
cooled packages. The heat exchangers require sufficient cooling water flow to operate efficiently – please
refer to Section 6 of this manual for detailed instructions on the operation and maintenance of water-
cooled heat exchangers, including minimum cooling water flow requirements.
