Powerex STS Series 5 HP Oil-Less Scroll Air Compressor – 80 Gallon

Powerex STS Series 5 HP Oil-Less Scroll Air Compressor – 80 Gallon (Simplex)

When your operation requires clean, oil-free compressed air with increased storage capacity, the Powerex STS Series 5 HP Simplex Oil-Less Scroll Air Compressor with 80-Gallon Tank delivers quiet, reliable performance for demanding clean-air applications. Built on Powerex’s proven scroll compressor technology, this system is designed for environments where air quality, uptime, and low maintenance are critical.

The STS Series utilizes 100% oil-less scroll pump technology, eliminating the risk of oil contamination while reducing long-term operating and maintenance costs. With smooth operation, extremely low vibration, and a compact tank-mounted design, this system is ideal for medical, laboratory, pharmaceutical, food processing, and precision manufacturing environments.

Clean, Quiet, Oil-Free Performance

The 5 HP simplex scroll pump is mounted directly to an 80-gallon corrosion-resistant air receiver, providing increased air storage for longer run times and reduced compressor cycling. The larger tank capacity helps maintain more stable system pressure during intermittent or higher-demand usage.

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 dependable airflow across both available pressure ranges:

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

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

This makes the system well suited for applications requiring clean, oil-free air at standard or elevated pressures with added air storage.

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.
