Atlas Copco ZT30 Air compressor

• Providing oil-free compressed air for pneumatic systems in food production lines.
• Supplying air for packaging machinery to operate grippers, valves, and actuators.
• Used in fermentation processes requiring clean, dry air for aeration.
• Powering air knives for drying or cleaning food products and packaging.
• Operating control systems and instrumentation in sensitive processing environments.

Compressor Type

Oil-free, air-cooled screw compressor, typically ensuring no oil contamination in the air supply.

Operating Pressure

Units in this class commonly operate around 7-10 bar (g).

Output Capacity

For a 30kW unit, output is typically in the range of 60-80 l/s (litres per second).

Motor Power

As indicated, 30 kW is standard for this model, influencing overall performance.

Air Treatment

Often supplied with an integrated or separate air dryer (e.g., desiccant or refrigeration type) to remove moisture.

Air Receiver

Typically paired with an air tank (receiver) to store compressed air and stabilise pressure.

Footprint

Compact for its class, but buyers should verify dimensions for installation space.

Noise Level

Modern oil-free screw compressors are designed for relatively low noise operation, but specific levels vary.

• What are the benefits of an oil-free compressor in food processing?

  Oil-free compressors eliminate the risk of oil contamination in the compressed air, which is critical for maintaining product hygiene and safety in food and beverage applications.

• What maintenance is typically required for this type of compressor?

• Is a separate air dryer always necessary?

• What power supply is typically needed for a 30kW compressor?

• How does an air receiver (tank) benefit the system?

• Can this compressor be used outdoors?

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.
