Profile: Compresstech Resources, Inc. specializes in providing compressed air systems. Our products include lubrication equipment, fluid handling pumps, air tools, hoist and winches. We offer high-pressure air, rotary compressors which can either be a scroll or screw type. These two differ in terms of capacity. Usually, scroll compressors are utilized by laboratories or hospitals, while their screw counterparts are used in big factories or manufacturing plants. Rotary compressors are pneumatic devices that convert power into energy stored in pressurized air. They do so by forcing gas into a storage chamber to increase its pressure.
