Vertical Air Tank 500L 20 bar for Screw Compressor CORMAK

The CORMAK air tank with a capacity of 500 litres and a working pressure of 20 bar is a reliable solution for storing compressed air in industrial facilities, workshops and pneumatic systems. Its robust steel construction and compliance with European Union directives make it an essential component of any compressed air installation. Thanks to its optimised design and high resistance to pressure, the tank can serve both as an air storage buffer and as a stabilising element for compressor performance.

Main advantages of the 500L air tank

• Professional pressure construction – made of high-grade steel, resistant to pressure and corrosion.
• CE certification – compliant with European safety and quality standards.
• Working pressure 20 bar – suitable for most pneumatic systems, including those with high operating requirements.
• High capacity – 500 litres – provides stable air supply and reduces compressor start frequency.
• Multi-connection system – six ports (1.1/4", 2", 1/2") enable flexible connection to different pneumatic systems.
• High-quality finish – durable external paint coating ensures long-term corrosion protection.
• Vertical installation design – space-saving and easy to integrate into workshop layouts.

Design and technology – solid construction for demanding applications

This compressed air tank is designed for intensive industrial use. The body, made of structural steel, ensures resistance to working pressure up to 20 bar and provides long-term durability. All welds undergo strict quality inspection, and the surface of the tank is coated with a chemical- and weather-resistant lacquer for maximum protection.

The tank is fitted with a nameplate bearing the CE marking, confirming compliance with European safety standards. The set includes full technical documentation, a pressure passport and material certificates.

Precision and performance – stable pressure and extended compressor lifespan

With a capacity of 500 litres, the tank acts as an air buffer, stabilising pressure throughout the pneumatic system. It ensures steady operation of compressed-air-powered devices and significantly extends the life of the compressor by reducing start-stop cycles. The vertical design allows for compact installation, ideal for industrial environments with limited space.

A properly selected air tank for a compressor minimises pressure drops and prevents system overload, ensuring higher efficiency and safety of the entire pneumatic installation.

Applications – versatile use in industrial and workshop environments

CORMAK air tanks are widely used across various industries, including automotive workshops, production facilities, construction companies and central compressed air systems. Due to their high capacity and pressure resistance, they are ideal as:

• Compressor air bottles – for storing compressed air in pneumatic systems,
• Compressor buffer tanks – stabilising pressure and reducing compressor cycles,
• Compressed air tanks – ensuring continuous air supply for pneumatic machinery,
• components of industrial automation and painting systems,
• key elements of pneumatic control systems.
