The QGS rotary screw compressor delivers 54.9 CFM at 125 PSI with a 100% duty cycle, giving multi-bay shops continuous air for demanding tool use without relying on recovery periods. Its standout feature is Auto-Dual operation, which allows programmed shutdowns during periods of no demand and automatic restart when scheduled. An integrated refrigerated air dryer is also included, while the package uses a 120-gallon horizontal receiver. Note: this configuration requires 208-230/460V, 3-phase power.
Auto-Dual addresses one of the less obvious costs of a rotary screw compressor: unnecessary standby operation. The compressor is designed to run continuously, but it does not need to maintain pressure all night when the shop is closed. Programmable shutdown lets the machine remain available during working hours and stop during predictable idle periods. When production resumes, it can restart without requiring someone to manually operate the compressor. The 54.9 CFM continuous output is suited to several technicians using impact wrenches, ratchets, air hammers and blow guns, with additional capacity for equipment such as sanders or small blast cabinets.
The integrated refrigerated air dryer handles moisture removal before compressed air enters the shop's distribution system. This model does not list an aftercooler, so the dryer carries the primary air-treatment load; keeping its condenser clean and confirming the required dewpoint before purchase are particularly important for demanding applications. A long-life V-belt drive provides straightforward service access, while premium synthetic lubrication is rated for 8,000 hours. TEFC motor construction, low-oil shutdown on the engine and pump, and an oil sight glass support routine operation.
This package is well suited to independent automotive shops, fabrication and welding facilities, woodworking operations and other commercial shops with extended air demand and periods of predictable downtime. Its horizontal configuration measures 76" long, 25" wide and 58" tall and weighs approximately 980 lbs, so it works well where wall length is available but floor width or ceiling height is limited. The receiver outlet is 1/2". Electrical service, feeder and disconnect sizing must be confirmed by a licensed electrician using the machine nameplate.
Confirm the Dryer Before Ordering
Published information conflicts on the integrated refrigerated dryer. The feature list and description say one is included, while the specification table says “No.”
If a built-in dryer is important, ask us to confirm the factory configuration before ordering. The specifications do confirm an aftercooler, which reduces discharge temperature and removes bulk moisture, but does not provide the same dewpoint as a refrigerated dryer.
