Screw compressors F-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.

Space-saving, clean and dry

Do you need clean, dry compressed air in a compact space? Comprag FRD complete systems are the turnkey solution. Mounted on a stable compressed air tank and equipped with an integrated refrigerated dryer, they deliver Class 4-4-4 (ISO 8573-1:2010) compressed air directly from a single, compact unit. Minimal installation time, maximum performance.

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 (F-series): Robust, reliable and easy to maintain - the proven basis for constant compressed air requirements.
• Direct drive (D and 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 t-log control

The professional t-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

Models (FRD)
Receiver-Mounted and complete with refrigeration dryer

Receiver-Mounted

Models (F)
Standard version on base frame

Comprag screw compressors are available in various designs, precisely tailored to the requirements of your operating environment. Whether as a space-saving individual component or as a ready-to-connect complete station - Comprag offers the right solution for your compressed air needs.

Models (FRD)
The Complete All-in- One System

The Comprag FRD screw compressors represent the most comprehensive solution. They are built on a horizontal tank and fully equipped with an integrated refrigerant dryer.
Your advantages in detail:

• Network stability and component protection: The horizontal tank maintains stable pressure in the network and prevents pulsation in the compressed air lines . This reduces the number of switching cycles in the operating mode of the Comprag screw compressor , which significantly extends the service life of the screw block, electric motor, and drive system , and leads to increased energy efficiency.
• Compressed Air Quality: The refrigerated dryer is crucial. It removes most of the moisture from the compressed air. This prevents water from accumulating in the compressed air lines , extends their service life, and protects the equipment powered by the compressed air.
• Easy Installation: Since all components (compressor, boiler, dryer) are pre-connected at the factory, you save considerable on-site installation time and costs . The Comprag FRD system is ready for immediate operation.

Models (FR)
The boiler-mounted, dryer-free solution

The Comprag FR screw compressors offer a compact solution, also based on a horizontal tank , but without an integrated refrigerant dryer.
Your advantages in detail:

• Network Stability and Service Life: As with the FRD series, the tank reduces pulsation in the compressed air lines. This results in fewer changeover cycles, which increases the service life of the screw block, electric motor and drive system , and contributes to a significant increase in the energy efficiency of the Comprag screw compressor.
• Cost and Assembly Savings: Since all compressor components are already connected, you save on installation time and costs . A refrigerated dryer can be flexibly and separately integrated into the compressed air line if required.

Models (F)
The standard version on a base frame

The Comprag F screw compressors are the standard version, mounted on a robust base frame.
Your advantages in detail:

• Flexibility and Space Saving: This is the space-saving version of the Comprag screw compressor for cases where the compressor is installed in a separate compressor station.
• Individual System Choice: All other components of the compressed air system - such as the compressed air tank, the refrigerated dryer, and the filters - can be selected as needed and installed externally. This offers maximum flexibility in designing your compressed air network.

Choose the Comprag screw compressor in the design that best suits your spatial conditions and quality requirements.
