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

Regular maintenance includes oil changes, filter replacements (air, oil, separator), and checking drive belts. Buyers should inquire about the service history of this specific unit.

Can this compressor be used for food-grade applications?

Standard industrial compressors are not typically suitable for direct food contact applications without additional filtration and certification. Specific oil-free models or advanced filtration systems are required for food-grade air.

What are the typical space requirements for a unit of this model?

While exact dimensions vary, units in this power class generally require a footprint of approximately 1.5m x 1m, plus space for ventilation and access.

Is an air receiver tank usually included or required?

An air receiver tank is almost always recommended or required to stabilise air pressure and store compressed air. It may be integrated or a separate component.

What are the electrical installation considerations for a 15kW compressor?

Installation typically requires a dedicated 3-phase power circuit with appropriate circuit breakers and cabling, sized according to the motor's full load current. Professional electrical installation is advised.

Typical context for this category of equipment. Always confirm specifics with the seller.

Supplying compressed air for pneumatic tools and machinery in workshops.
Powering industrial processes requiring consistent air pressure.
Use in manufacturing facilities for assembly lines and automation.
Providing air for spray painting and surface finishing operations.

Compressor type: Rotary screw, commonly found in industrial settings for continuous operation.
Motor power: Units of this class typically feature motors in the 11 kW to 22 kW range.
Working pressure: Commonly operates at pressures around 7 to 10 bar, suitable for most industrial applications.
Air delivery rate: For a 15kW unit, free air delivery (FAD) typically ranges from 1.5 to 2.5 m³/min.
Power supply: Industrial compressors of this size typically require a 400V, 3-phase electrical supply.
Cooling method: Most industrial rotary screw compressors utilise air cooling, sometimes with an integrated aftercooler.

Regular maintenance includes oil changes, filter replacements (air, oil, separator), and checking drive belts. Buyers should inquire about the service history of this specific unit.

Used air compressors are valued for their durability and cost-effectiveness in industrial applications. Buyers typically prioritise checking maintenance history, motor condition, and tank integrity, as these significantly affect performance and longevity. Industry sentiment favours established brands known for reliability. Common strengths include robust construction, long operational lifespan when properly maintained, and substantial savings compared to new equipment. Prospective purchasers should verify pressure ratings and output capacity match their operational requirements before committing to purchase.
