Screw compressors FV-Serie

Application and your benefits: Why a Comprag screw compressor?

Reliable performance - 24/7 operational reliability

A Comprag screw compressor guarantees uninterrupted production. Our machines are specifically designed for demanding 24/7 continuous operation in challenging industrial environments. From small workshops to large production lines - rely on technology that minimizes downtime and ensures the availability of your compressed air at all times.

Maximum efficiency: The frequency-controlled Comprag FV and DV screw compressors

If your compressed air demand fluctuates significantly throughout the day or week, conventional fixed-speed screw compressors are no longer economical. This is where the intelligent technology of the frequency-controlled Comprag FV and DV series comes in, offering the ultimate solution for efficient energy management.

Why frequency control is the future of compressed air

Conventional screw compressors are unable to precisely adjust to the current compressed air demand. They frequently switch between full load and idle operating states. Idle operation, in particular, consumes an unnecessarily large amount of electrical energy - a huge cost trap.

The Comprag FV series (with belt drive) and the DV series (with direct drive) were specifically developed for economical operation with changing compressed air requirements.

Benefit from heat recovery

Utilize the waste heat from your Comprag screw compressor as a free energy source. Up to 94% of the supplied electrical energy can be recovered through optional heat recovery systems - ideal for heating your premises. An active contribution to reducing your energy costs and improving your CO₂ balance.

Features and technology: The heart of every Comprag screw compressor

The durable Comprag screw block

At its core is our specially developed screw block with rotor design . It is designed for contactless rotation and maximum mechanical efficiency. Precise oil injection seals, lubricates, and dissipates process heat, maximizing the service life of the entire Comprag screw compressor and extending maintenance intervals.

Drive concepts for every requirement

We offer you the right drive solution for maximum cost-effectiveness:

• Belt drive (FV series): Robust, reliable and easy to maintain - the proven basis for constant compressed air requirements.
• Direct drive (DV series): The low-loss and low-wear 1:1 direct drive. Increases mechanical efficiency, reduces vibrations, and eliminates the need for belt changes, guaranteeing an exceptionally long service life for the Comprag screw compressor.

Intelligent v-log control

The professional v-Log control system monitors your Comprag screw compressor fully automatically. The system provides you with all relevant data (pressure, temperature, maintenance intervals) in real time, optimizes the load/idle cycle, and can be easily integrated into higher-level building management systems to continuously increase process reliability.

Excellent maintainability

Thanks to its well-thought-out, service-oriented design, all maintenance components, such as filters and oil separators, are optimally positioned and easily accessible. This concept reduces downtime to a minimum and actively contributes to keeping the total operating costs of your Comprag screw compressor low.

Comprag screw compressors: Design and specifications

Version FV
Standard version on base frame

Comprag screw compressors form the basis of our reliable compressed air generation. They produce industrially compressed air of the highest quality, optionally with an integrated refrigerant dryer, achieving the demanding class 4-4-4 according to ISO 8573-1:2010.
The robust design of Comprag compressors focuses on the durability and efficiency of its core components:

1. Reduce operating costs - Save up to 25% on energy

Analysis of the operating costs of a compressor shows that the lion's share of the costs (approx. 78%!) is attributable to energy.

• Intelligent adjustment: The frequency-controlled Comprag screw compressors are equipped with a frequency converter . This continuously measures the current system pressure and sends a corresponding signal to the control unit.
• Variable speed: The control system precisely adjusts the speed of the electric motor to the required volume of compressed air. The Comprag compressor therefore delivers only as much power as is actually needed.
• Your savings advantage: By avoiding idle times and precisely controlling the workload, Comprag compressors with frequency control enable savings of up to 25% in electricity consumption compared to compressors without frequency control.

2. Consistent compressed air quality and optimized service life

The function of the compressor with frequency control goes beyond mere energy saving:

• Constant system pressure: Thanks to the stepless control of the airflow, the system pressure in the compressed air network can be kept at a constant, optimal value . This is essential for the quality and stability of your production processes.
• Soft start function: The frequency converter ensures very low starting currents when starting the compressor. As the graph shows, the starting currents of a frequency converter are significantly lower than those of star-delta or even direct starters. This has a positive effect on the service life of the electric motor and the entire electrical system.

3. Comprag FV and DV series: The perfect choice for dynamic processes

Choose the frequency-controlled Comprag screw compressor and benefit from a solution that intelligently adapts to your individual operating process - from Monday to Sunday, from peak load to the night shift.

• FV series: Efficient frequency control with robust belt drive.
• DV series: Maximum efficiency through a combination of frequency control and low-wear direct drive.
