Mobile Air Compressor Systems
Air Compressor

Feed-Air Screw compressors gather air through an air filter at normal atmospheric pressure at an ambient temperature up to 131°F (55°C). The air is compressed from atmospheric 14.5 psig pressure to 350-psig (24-bar) using Sullair 2-stage compressors. A vertical cooler then cools the air to 120°F (49°C) before it is delivered through a common manifold to GENERON® nitrogen membranes. Each screw compressor is driven by a Caterpillar C-27 engine. Feed-air screw compressors are identical with the compressor and engine mounted inside their own Frame. Each skid contains a process cooler, a radiator for cooling the glycol, and lubrication oil used in the package. Coolers are belt driven which allows fan speeds to match operating conditions. Both the radiator and cooler are specifically mounted for easy removal.

Operating Shipping for ocean freight is the most direct and cost-effective method of delivery or transport.
