Powerex STS Series 5 HP Oil-Less Scroll Air Compressor – 30 Gallon (Simplex)

For applications that demand higher airflow with uncompromising air purity, the Powerex STS Series 5 HP Simplex Oil-Less Scroll Air Compressor with 30-Gallon Tank delivers clean, quiet, and dependable compressed air in a compact footprint. Built on Powerex’s proven scroll compressor technology, this system is ideal for environments where oil contamination, excessive noise, and high maintenance are unacceptable.

The STS Series utilizes 100% oil-less scroll pump technology, eliminating the risk of oil carryover while reducing long-term maintenance and operating costs. With smooth operation, extremely low vibration, and a space-saving tank-mounted design, this compressor is well suited for medical, laboratory, pharmaceutical, food processing, and precision manufacturing applications.

Clean, Quiet, Oil-Free Performance

The 5 HP simplex scroll pump is mounted directly to a 30-gallon corrosion-resistant air receiver, providing a compact solution for facilities that need higher air output but have limited floor space. The tank-mounted configuration allows easy access for service while maintaining a small overall footprint.

The system comes standard with an electronic condensate drain, automatically removing moisture from the tank 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 STS Series 5 HP oil-less scroll compressor delivers reliable airflow at both available pressure settings:

  • Approximately 15.2 SCFM at 116 PSI (standard pressure configuration)

  • Approximately 12.5 SCFM at 145 PSI (high-pressure configuration)

This performance makes the system ideal for applications requiring clean, oil-free air at standard or elevated pressures.

Configurable Dryer Options

The STS 5 HP system can be configured to match your specific air quality requirements:

  • No Dryer – For facilities with existing air treatment or non-critical applications

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

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

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