Sullair ShopTek ST510

Sullair ShopTek ST510 is a 7.5 HP single-stage rotary screw compressor delivering roughly 26 SCFM at 125 PSI on an 80-gallon horizontal tank, with 150 PSI maximum operating pressure. The ST510 is the 7.5 HP point in the ShopTek 4-15 kW lineup, available single-phase 230V (the R-suffix tank-mount) and three-phase, with an optional integrated refrigerated dryer. The package uses Sullube biodegradable polyglycol fluid with a 10,000-hour service interval, which is roughly double a mineral-oil-based rotary screw and a meaningful operating-cost advantage. Sullair’s microprocessor controller manages load/unload, run hours, alarms, and shutdown protection. AirCompressorsDirect lists the ST510 in their catalog with stocked configurations. Sullair’s 5-Year Emerald Warranty applies when proper fluid maintenance is followed. Best for 2-3 bay auto and tire shops, woodworking shops with continuous spray demand, body shops, and small fabrication facilities.
