Powerex STS10B4 Series 10 HP Oil-Less Scroll Air Compressor – 120 Gallon (Simplex)

For facilities that require higher continuous airflow with uncompromising air purity, the Powerex STS10B4 Series 10 HP Simplex Oil-Less Scroll Air Compressor with 120-Gallon Tank delivers exceptional performance in clean-air environments. Built around Powerex’s advanced scroll compressor technology, this system is engineered for applications where oil contamination, excessive noise, and downtime are unacceptable.

The STS Series utilizes 100% oil-less scroll pump technology, eliminating the risk of oil carryover while reducing maintenance and total cost of ownership. With smooth operation, extremely low vibration, and a compact tank-mounted footprint, this system is ideally suited for medical, laboratory, pharmaceutical, food processing, and precision manufacturing applications with higher air demand.

Clean, Quiet, Oil-Free Performance

The 10 HP simplex scroll pump is mounted directly to a 120-gallon corrosion-resistant air receiver, providing increased air storage to support higher airflow requirements while helping reduce compressor cycling. This configuration delivers stable system pressure for continuous or simultaneous air usage.

The system comes standard with an electronic condensate drain, automatically removing moisture from the air receiver to protect downstream equipment and maintain air quality without manual draining.

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

• No oil changes

• No oil carryover

• No oil-water separators required

• Reduced downstream filtration requirements

Airflow Performance

The Powerex STS10B4 oil-less scroll compressor delivers robust airflow for clean-air applications:

• Approximately 31.2 SCFM at standard operating pressure

This increased airflow makes the 10 HP STS system an excellent solution for facilities with higher continuous or multiple point-of-use air demand while maintaining oil-free air quality.

Configurable Dryer Options

The STS10B4 system can be configured to meet your specific air quality requirements:

• No Dryer – For facilities with existing air treatment

• Refrigerated Air Dryer – Removes moisture to protect piping, tools, and equipment

• Desiccant Air Dryer – Provides ultra-dry air for critical processes requiring very low dew points

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