Screw air compressor with frequency control 45 kW, 5–7 bar, 400V, 7500 l/min FV-4508 Comprag

Country of origin: Germany, warranty period – 24 months

The FV-4508 Comprag screw air compressor is an advanced, energy-saving, and highly reliable solution for industrial companies that require a stable compressed air supply with optimized power consumption. This frequency-controlled (inverter) compressor automatically adapts to the actual compressed air demand, consuming only as much energy as needed at any given time. This allows for up to 25% electricity savings compared to conventional compressors. The FV-4508 is ideal for continuous operation in production, assembly, and maintenance environments where quiet operation, efficiency, and durability are essential.

The screw air compressor with frequency control 45 kW, 5–7 bar, 400V, 7500 l/min FV-4508 Comprag can be configured with the following option:

• 5–10 bar, 6500 l/min

Functions:

• FV-Series oil-lubricated screw compressors produce industrial compressed air and can optionally be equipped with a refrigerated air dryer, achieving class 4-4-4 according to ISO 8573-1:2010.
• Frequency control – the compressor automatically adjusts motor speed according to actual air demand, maintaining constant system pressure and reducing power consumption
• No idling – the compressor does not consume electrical energy when there is no air demand
• Constant system pressure – eliminates pressure fluctuations and pulsations in the air network
• Reduced air losses and lower maximum system pressure – reduces energy consumption and extends component lifespan
• Soft start – the frequency converter ensures a low starting current, positively affecting the longevity of the motor and electrical system
• A modern, energy-efficient screw air-end ensures efficient and reliable operation even under demanding conditions
• The professional t-Log microprocessor controller automatically manages compressor operation and provides data on pressure, air–oil mixture temperature, and operating time
• A reliable electric motor with a high efficiency coefficient, bearings from leading manufacturers, power reserve, and thermal protection against overheating
• An efficient three-stage oil separation system – oil is separated by centrifugal, gravitational, and filtration forces, ensuring that the residual oil content in the compressed air does not exceed 3 mg/m³
• Easy maintenance – all filters and separators are easily accessible, making servicing simple, fast, and cost-effective
• Quiet operation – sound level only 75 dB(A), making the unit suitable for working environments where comfort and low noise levels are important
