The heart of most industrial compressed air systems is the oil-flooded rotary screw air compressor. From 5 to 500 horsepower, single or two stage, high or low pressure, Scales has a broad range of oil-flooded air compressors to match your needs. Our variable displacement and variable frequency drive units can provide the ultimate solution in part load energy efficiency and energy savings.
5 to 30 Horsepower
Our standard line of small rotary air compressors come completely packaged to meet your everyday needs. These units provide the flexibility to allow you to put them anywhere, even where space is at a minimum and are available in both base mount and tank mounted designs. Choose from standard unenclosed units with a minimum of controls to quiet enclosed units with the most up-to-date microprocessor controllers.
Our premium line of small rotary screw air compressors provide long lasting reliability through the use of large, slow speed air ends. Slower air end speeds provide you with extended air end life and quiet, economical, efficient operation. Controls include modulation, on-line off-line, and the latest microprocessor controls complete with lead lag control options. The premium line is available in both base mount and tank mounted designs.
40 to 500 Horsepower
Our broadest product lines include offerings in this size range. Packages are available in all drive types including direct drive, belt and gear driven models. Our standard lines include belt driven units in 40 and 50 horsepower sizes. They offer a wide range of flexibility in horsepower, flow, and pressure ranges. This line offers efficiency and value at an economical price.
Our premium line of large oil-flooded rotary screw air compressors will provide long lasting reliability through the use of large, slow speed air ends. Slower air end speeds provide you with efficient operation, extended air end life and low sound. Available controls include modulation, on-line off-line, low demand modes, and the latest microprocessor controls that also include built in lead lag and networking control options.
