11 BAR 500L Pressure Container

CORMAK Zbiornik ciśnieniowy OCYNK 11 BAR 500 L

The CORMAK 500-litre pressure vessel, with a working and maximum allowable pressure of 11 bar, is designed for storing compressed air in industrial facilities, workshops, and pneumatic systems. The tank is made of galvanized steel sheet, providing an excellent protective barrier against external factors and corrosion and significantly extending the service life of the unit compared with standard painted tanks.

Its robust steel construction, compliance with European Union directives, and UDT certification make this tank an essential component of any compressed air system. Thanks to its optimized design and high pressure resistance, it can serve both as a storage buffer and as an element for stabilizing compressor operating parameters.

Key Features of the 500 L Galvanized Pressure Vessel
Professional pressure-rated construction – made of high-quality 4 mm thick steel, resistant to pressure and corrosion.
Galvanized finish – the tank surface is galvanized, providing an attractive appearance and high resistance to demanding conditions in workshops and production halls.
UDT certification and CE marking – compliance with European safety and quality standards.
11 bar working pressure – suitable for most pneumatic systems, including those with higher operating requirements.
High 500-litre capacity – provides stable compressed air supply and reduces the frequency of compressor start-up cycles.
Multiple connection ports – 6 connection ports with diameters of 1 1/4", 2", and 1/2" allow flexible connection to various installations.
High-quality construction – durable galvanized external coating provides long-lasting protection.
Space-saving vertical design – allows efficient use of available space in the workplace.
Compliance with standards – the tank meets pressure equipment safety requirements and is suitable for registration with the Polish Office of Technical Inspection (UDT).
Construction and Technology – Robust Design for Demanding Applications
This compressed air tank has been designed for intensive use in industrial environments. The body is made of structural steel with a 4 mm wall thickness, ensuring resistance to pressures of up to 11 bar and providing long-term durability. All welds undergo rigorous quality control, while the tank surface is protected with a galvanized coating resistant to external factors and corrosion.

The tank is equipped with a nameplate bearing the CE symbol and the UDT notified body number, confirming its approval for use on the Polish and European markets. The set includes complete technical documentation, a pressure vessel passport, and material certificates.
