Screw compressors

Screw compressors – how do they work?

A screw compressor is a mechanical device that increases the pressure and density of air or gas by reducing its volume. The compressed air is then stored in a dedicated air tank, ready for use in various industrial processes. This technology is essential wherever pneumatic power or process control is required. Our screw compressors deliver consistent pressure and high output, enhancing the efficiency of your production line.

Screw compressors – working principle and technological advantages

Screw compressors are advanced pneumatic devices that compress air through the rotation of two intermeshing helical rotors. As they turn in opposite directions, the space between them decreases, compressing the air and increasing its pressure. This contact-free and continuous method ensures excellent efficiency, quiet operation and high reliability – even under intensive use.

CORMAK screw compressors are based on modern engineering solutions such as:

• High-performance screw stages with optimised geometry for maximum energy efficiency.
• Inverter technology allowing variable speed control, which reduces energy consumption and extends component life.
• Anti-vibration systems improving comfort and reducing mechanical wear.
• Modern drive systems with direct coupling between motor and screw module, eliminating energy loss from belts or gears.
• Digital control panels with intelligent monitoring, diagnostics and remote management features.

Thanks to innovative design and robust construction, CORMAK compressors are widely used in manufacturing, automotive, metalworking and industrial pneumatic systems.

What are screw compressors made of?

A screw compressor consists of a screw unit that compresses air by reducing the chamber volume. It is driven by an electric motor, usually asynchronous, directly coupled or belt-driven. Cooling systems – oil or air-based – maintain optimal operating temperature. An oil separator removes lubricant from the compressed air, while air filters protect the system from contaminants.

Operation is managed via a digital control panel that monitors pressure, temperature, operating time and service intervals. Inverter models allow variable motor speed control according to air demand. Compressors can also include integrated refrigeration dryers and air tanks for stable pneumatic performance.

Maintenance and servicing

Regular maintenance includes oil and filter replacement (air, oil, separator), and inspection of coolers and seals. These tasks are typically performed every 2000–4000 operating hours as per manufacturer’s recommendations. In inverter models, drive and control parameters should be periodically checked.

Cormak provides full service support – from spare parts supply and warranty maintenance to technical assistance. This ensures uninterrupted operation and rapid response in case of faults.

Vane compressors

Vane compressors belong to the displacement compressor group, where compression is achieved by reducing the working chamber’s volume. The key component is a rotor with sliding vanes rotating inside an eccentric casing. As the rotor spins, the vanes move in and out, forming variable chambers that efficiently compress air.

CORMAK vane compressors are designed for maximum reliability and simplicity:

• Few moving parts reduce failure risk and maintenance costs.
• Compact construction allows installation in confined areas – ideal for workshops, labs or service stations.
• Low operating speed ensures exceptionally quiet operation and minimal wear.
• Constant air flow and pressure stability make them ideal for applications requiring precise pneumatic supply – such as automation, packaging, printing or medical sectors.

Thanks to their simplicity, quiet operation and reliability, CORMAK vane compressors are an excellent choice for continuous operation.
