Single-stage compressor

The 7500 S-energy Series with Energy Efficiency System (EES) heat recovery is Sullair's most energy-efficient single-stage compressor, according to the company. The lubricated rotary-screw air compressor is available in constant-speed- and variable-speed-drive models with 100 horsepower, capacities of 369 to 493 acfm and pressures from 100 to 175 psig. The EES enables the heat of compression to be recovered and converted into recirculating air for comfort heating in plants, or into preheated air for boilers or processes. Energy-saving features include: an air-end design with a low-restriction inlet valve; a low-pressure drop air-fluid separation system that prevents energy loss; and a high-efficiency fan. Package designs meet the need for a small footprint, and enclosures allow routine maintenance of consumable items to be performed from the same side of the compressor.
