• Providing compressed air for general workshop tools and pneumatic machinery.
• Powering industrial processes such as packaging, assembly lines, and material handling.
• Supplying air for spray painting booths and surface finishing applications.
• Operating control systems and instrumentation in manufacturing plants.

Typical pressure range

Rotary screw compressors commonly operate between 7 to 10 bar (100-145 psi).

Typical flow rate (FAD)

For this class of equipment, free air delivery (FAD) typically ranges from 10 to 100 CFM (cubic feet per minute), or 0.3 to 2.8 m³/min, depending on motor size.

Power supply

Units of this type commonly require a 3-phase electrical supply, typically 400V or 415V, 50Hz.

Cooling method

Most rotary screw compressors are air-cooled, though larger units may feature water cooling.

Footprint

The footprint for a standalone unit typically ranges from 1m x 0.8m to 2m x 1.2m, excluding external air receivers or dryers.

Noise level

Modern enclosed rotary screw compressors typically operate at noise levels between 65-75 dB(A).

Air quality

When paired with a refrigerant dryer, as mentioned, the output air quality is suitable for most general industrial applications, reducing moisture content significantly.

• What is a rotary screw air compressor?

  A rotary screw air compressor uses two meshing helical screws to compress air. They are known for continuous duty operation, energy efficiency, and a steady supply of compressed air.

• Why is a refrigerant compressed air dryer important?

• What does '7 Bar Pressure' mean?

• Can the included piping be reused?

• What maintenance is typically required for a rotary screw compressor?

• Is this unit suitable for continuous operation?

Used air compressors for lab and pharma applications are generally valued for reliability and cost savings. Buyers typically prioritize checking maintenance history, confirming pressure ratings meet specific requirements, and verifying oil-free operation where contamination control matters. Key strengths include durability when properly serviced, consistent performance across extended operational hours, and significant capital cost reduction compared to new units. Inspecting seals, checking for corrosion, and confirming recent servicing records are standard considerations when purchasing secondhand.
