Compressed Air Tanks & Receivers in Mild Steel
Our series-produced mild steel pressure vessels are ideally suited as compressed air tanks and compressed air receivers in industrial compressor systems.
Compressed air reservoir for compressor systems
As a compressed air tank, our mild steel pressure vessels buffer compressed air between the compressor and consumers. Pressure peaks are reliably equalised, switching frequency is reduced, and system efficiency is noticeably improved.
Whether as a compressed air tank in a workshop, a compressed air receiver in production, or a central compressed air reservoir in large compressor stations – the pressure ratings of 11 and 16 bar cover the typical operating pressures.
Tip: Galvanised compressed air receivers are particularly suitable for outdoor installation – the zinc coating provides long-term corrosion protection even in humid conditions.
Nitrogen tank & industrial gas supply
Our mild steel pressure vessels are equally suitable as nitrogen tanks for industrial gas supply. In laboratories, packaging plants, or the food industry, nitrogen pressure vessels ensure a reliable supply of inert gas.
CE/PED certification guarantees standards-compliant operation across all industries. Both pressure ratings (11 and 16 bar) cover the typical operating pressures for industrial gas supply.
Good to know: All models are available in either sandblasted & primed or hot-dip galvanised finish – to suit your installation site.

Applications for Steel Pressure Vessels
Mild steel pressure vessels are the first choice when cost-effectiveness, robustness and short delivery times matter – whether as a compressed air reservoir, steel vessel for water, or nitrogen tank. Typical fields of application:
Compressor systems (air reservoirs)
Building services (heating/cooling)
Water & fire suppression systems
Industrial gas supply (nitrogen)
Steel vs. Stainless Steel – Which Pressure Vessel Do You Need?
The choice between mild steel pressure vessels and stainless steel pressure vessels depends on the medium used, the installation site, and hygiene requirements. Here you will find the key differences at a glance.
| Criterion | Mild steel (carbon steel) | Stainless steel |
|---|---|---|
| Suitable media | Compressed air, water, nitrogen, neutral gases | Additionally: acids, alkalis, corrosive media, food contact |
| Corrosion resistance | Good with surface protection (sandblasted/primed or galvanised) | Very high – inherent to the material, no coating required |
| Acquisition cost | Lower – attractive price-performance ratio | Higher – material cost and processing more complex |
| Delivery time | Many sizes available ex-stock at short notice | Often made-to-order or longer delivery times |
| Hygiene requirements | Not suitable for food contact or cleanroom applications | Suitable for pharmaceutical, food, and cosmetic applications |
| Outdoor installation | Galvanised version recommended | Permanently weather-resistant without additional protection |
| Certification | CE/PED 2014/68/EU | CE/PED 2014/68/EU |
Our recommendation: For neutral media such as compressed air, water, or nitrogen, a mild steel pressure vessel is the most cost-effective solution – especially when short delivery times are required. Many standard sizes are available directly ex-stock.
For corrosive, hygienic, or food-processing media, we recommend our – with higher corrosion resistance and suitability for demanding operating environments.

Frequently Asked Questions About Steel Pressure Vessels
The price depends on volume, pressure rating (11 or 16 bar), and surface finish (sandblasted/primed or galvanised). Pressure vessels from 1,000 litres are available – we calculate daily updated prices promptly on request. Request a quote now.
Many standard sizes up to 3,000 litres are available ex-stock at short notice. Larger volumes are manufactured to order with short delivery times. Contact us for a binding delivery commitment.
Mild steel vessels are more affordable to purchase and ideal for neutral media such as compressed air, water, or nitrogen. excel with hygienic or corrosive media thanks to higher corrosion resistance – but come at a higher cost.
No. Up to 3,000 litres, a type examination is in place – no individual TÜV inspection is required. From 4,000 litres, an individual TÜV inspection is mandatory. In both cases, you receive CE marking in accordance with PED 2014/68/EU.
Sandblasted & primed is the standard solution for dry indoor environments. Galvanised provides additional corrosion protection – recommended for outdoor installation or humid environments.
Yes. In addition to the 22 series variants (1,000–10,000 litres), we also manufacture custom sizes and individual configurations on request. Pressure rating, connections, and surface treatment can be adjusted. Get in touch.
All pressure vessels are CE-compliant in accordance with the Pressure Equipment Directive 2014/68/EU (PED). Up to 3,000 litres, a type examination is in place; from 4,000 litres, an individual TÜV inspection is carried out. Manufacturing follows the AD 2000 code of practice.
Yes. Mild steel pressure vessels are designed for use as compressed air reservoirs in compressor systems. They buffer compressed air between the compressor and consumers, equalising pressure peaks. Both pressure ratings (11 and 16 bar) cover typical operating pressures. Also suitable as a nitrogen tank.
Yes, our mild steel pressure vessels are frequently used as compressed air tanks in compressor systems. As compressed air receivers, they serve to buffer air and stabilise pressure. The pressure ratings of 11 and 16 bar cover the typical operating pressures of piston and screw compressors. All vessels are CE/PED-certified and ready for immediate operation.
The optimal volume depends on compressor output and consumption profile. As a rule of thumb: the vessel volume in litres should be at least equal to the compressor output in l/min. For smaller workshops, 1,000–3,000 litres is typical; for larger production plants, 5,000–10,000 litres. We are happy to advise you on sizing – contact us.
Yes. For outdoor installation, we recommend the hot-dip galvanised version. The zinc coating protects the steel long-term against weathering and corrosion. In the product overview you will find the item number for the galvanised variant for each size.
