When your operation requires clean, oil-free compressed air with added storage capacity and quiet, dependable performance, the Powerex STS Series 3 HP Simplex Oil-Less Scroll Air Compressor with 60-Gallon Tank is an excellent solution. Built around Powerex’s proven scroll compressor technology, this system is engineered for environments where air quality, reliability, and low maintenance are critical.

The STS Series uses 100% oil-less scroll pump technology, eliminating the risk of oil contamination while reducing maintenance and long-term operating costs. With extremely low vibration and quiet operation, this compressor is well-suited for medical, laboratory, pharmaceutical, food processing, and precision manufacturing applications.

Clean, Quiet, Oil-Free Performance

The 3 HP simplex scroll pump is mounted directly to a 60-gallon corrosion-resistant air receiver, providing increased air storage for longer run times and reduced compressor cycling. The tank-mounted design maximizes floor space while allowing easy access for service and inspection.

To protect the air receiver and downstream equipment, this system comes standard with an electronic condensate drain, automatically removing moisture without manual draining.

Because the system is completely oil-free, users benefit from:

• No oil changes

• No oil carryover

• No oil-water separators required

• Reduced downstream filtration requirements

Configurable Dryer Options

Dryer options are factory-integrated for a clean, space-saving installation.
