Equipment: Oil Free Air Compressors
The Oil Free Rotary Screw air compressor assembly is designed and constructed to exacting quality standards. These standards result in assemblies with long operating life, minimum maintenance, and low operating costs.
They are designed, manufactured, assembled, and tested in the United States and are delivered ready for operation. The two-stage rotary screw air compressor provides completely oil-free air because no oil is allowed in the compression chambers.
Both compression stages employ a new patented Super Rotor Design, which is acknowledged to be the most efficient, two-stage, oil-free rotary screw air compressor on the market. This new asymmetric rotor profile provides the lowest power consumption per cubic foot of compressed air, currently on the market. The efficiency is further enhanced by a unique load/unload control system that is simple and trouble free.
The compressor air-end is a heavy-duty, two-stage design with each stage driven by a common gear. These components are arranged in a single modular design to form a compact unit which is mounted on vibration isolators to a structural steel base. No special foundation considerations are required.
Capitol Air Systems offers a broad line of oil free centrifugal air compressors, each designed for long lasting performance, easy operation and convenient service. Our current rental fleet for this type of compressor ranges from 550 CFM through 3333 CFM. Other configurations are available up to 70,000 CFM.

High quality, 100% oil-free compressed air is required not only in the pharmaceuticals, food, electrical engineering and medicine sectors; it is also used wherever top quality products are produced. Water, the most natural of all raw materials, is used in the compression process as a coolant instead of oil.
The result:
-
• Clean, environmentally friendly oil-free compressed air
• Clean condensate - pure water - can be discharged straight into the normal wastewater system.
• Extremely low air end temperatures
• Variable Speed Technology (VSD) for highest rebates and energy savings!
