Sullair Corporation has announced the redesign of its 200hp compressors, which feature the company's single-stage rotary screw air end. These compressors are offered with a choice of constant-speed-drive models (LS-200S) or constant-speed drive with variable capacity control (VCC-200S and VCC-250S). These 200hp compressors have capacities ranging from 457acfm to 980acfm and pressure ranges from 100psig to 175psig.The variable-speed-drive (VSD) model, V-200S, with capacities of 576acfm to 967acfm, completes the compressor offering. These compressors have flange-mounted motors and air ends to provide positive alignment and to extend bearing life in both. Variable capacity control is achieved with Sullair's spiral valve technology. Part-load capacity and efficiency can produce energy savings up to 17-30 per cent.
The V-200S compressor with a VSD achieves further part-load and full-load energy savings. These Sullair compressors are available with or without sound-attenuating enclosures and with a choice of water-cooled or air-cooled models. All models feature the company's multi-stage air-fluid separation with a dual nested optimiser separator element to minimise fluid carryover.
The Optimalair heavy-duty air intake filter reduces pressure drop for additional energy savings throughout its operating life. The Sullair compressors also feature an advanced upgrade of the company's Supervisor Controller. This computer-compatible microprocessor control unit provides critical operating information using graphics of monitored functions and stop/start, sequencing and activation controls.
