Screw compressors FV-Serie

General product description: Comprag FV and DV series screw compressors (frequency controlled)

The Comprag FV and DV screw compressors are oil-injected screw compressors with variable speed drive (VSD) . They were designed as the ultimate solution for modern industrial applications where compressed air demand fluctuates significantly during operation. Thanks to intelligent frequency control, these compressors adjust continuously and precisely to actual consumption. They combine maximum energy efficiency, process stability, and a robust design built for uninterrupted 24/7 operation.

Invest in the future of your compressed air supply and benefit from maximum efficiency and operational reliability.

The main advantages of the FV and DV series:

• Unrivaled energy efficiency through frequency control: VSD technology eliminates costly idle times and precisely adjusts the output to the demand. With fluctuating consumption, you save up to 25% on electrical energy compared to fixed-speed compressors .
• Maximum efficiency through direct drive (DV series): The DV series combines frequency control with a low-wear 1:1 direct drive . This results in higher mechanical efficiency, eliminates transmission losses and belt changes, thus increasing service life and further reducing operating costs. The FV series offers efficient frequency control with a robust belt drive.
• Consistent process quality and smooth start-up: The stepless control ensures a consistently optimal system pressure in the compressed air network, which is essential for the stability of your production processes. Furthermore, the frequency converter ensures a smooth start-up (soft starter function) with very low starting currents. This protects the electric motor and the entire electrical system.
• Intelligent v-Log microprocessor control: The professional v-Log control monitors all relevant operating parameters in real time (pressure, temperature, maintenance intervals) and optimizes automatic operation fully automatically and cost-effectively.
• Durability and 24/7 operational reliability: Equipped with high-quality, highly efficient electric motors with ample energy reserves, as well as the durable Comprag screw block. The contactless rotation of the screw pair (protected by a thin film of oil) ensures maximum service life, even under demanding continuous operation.

The right dynamic compressed air solution for every application

Thanks to their adaptability and low sound pressure level, the frequency-controlled Comprag screw compressors are ideally suited for a wide range of demanding industrial environments:

• Industry with highly fluctuating demand: The FV and DV series are the most economical choice for production facilities whose compressed air consumption varies depending on the shift, day of the week or production capacity.
• Sensitive manufacturing processes: To ensure high product quality, an optional FRD complete system (on compressed air tank with integrated refrigerated dryer) can be selected, which delivers clean, dry compressed air of the demanding quality class 4-4-4 (ISO 8573-1:2010) .
• Decentralized installation: The low-vibration design and the low sound pressure level (especially with the direct drive of the DV series) often allow for decentralized installation of the compressor near production.

Quality and construction: Maximum efficiency and ease of maintenance

• Premium components: At its core are the energy-efficient Comprag screw block and the high-quality electric motor. The contactless rotation within the screw block guarantees minimal wear.
• Heat recovery (optional): Use your compressor as an energy source. Up to 94% of the supplied electrical energy can be used for heating halls or for hot water preparation through optional heat recovery systems.
• Excellent maintainability: The well-thought-out, service-oriented design ensures easy access to all filters, oil separators, and valves. This drastically reduces maintenance times, minimizes downtime , and ensures low life cycle costs.
