Powerex STS Series 3 HP Oil-Less Scroll Air Compressor – 30 Gallon

Powerex STS Series 3 HP Oil-Less Scroll Air Compressor – 30 Gallon (Simplex)

When your application demands clean, oil-free compressed air with quiet operation and long-term reliability, the Powerex STS Series 3 HP Simplex Oil-Less Scroll Air Compressor is built for the job. Designed around Powerex’s proven scroll technology, this tank-mounted system delivers dependable performance for environments where air quality cannot be compromised.

Powered by a 100% oil-less scroll pump, the STS Series eliminates the risk of oil contamination while dramatically reducing maintenance requirements. With fewer moving parts, extremely low vibration, and quiet operation, this system is ideal 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 30-gallon corrosion-resistant air receiver, maximizing floor space while allowing easy access for maintenance. Scroll compressors operate with significantly less noise and vibration than comparable reciprocating compressors, making them well-suited for noise-sensitive environments.

To protect the tank and downstream equipment, the STS Series comes standard with an electronic condensate drain, automatically removing moisture from the system without manual intervention.

Because the system is completely oil-free, there are:

• No oil changes

• No oil carryover

• No oil-water separators required

• Reduced downstream filtration requirements

Configurable Dryer Options

This compressor system can be configured to match your exact air quality needs:

• No Dryer – Ideal when air treatment already exists or for non-critical applications

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

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

Dryer options are factory-integrated for a compact, professional installation.

Voltage & Electrical Flexibility

To accommodate a wide range of facilities, customers may select from the following voltage options:

• 230V / Single Phase

• 230V / Three Phase
