Frauenthal Air Tanks – Used OEM Brake Air Reservoirs for European Trucks

Frauenthal air tanks for modern European HGVs

Frauenthal Airtank is one of Europe’s leading manufacturers of steel air tanks and pressure vessels for commercial vehicles, with highly automated plants in Elterlein (Germany) and Hustopeče (Czech Republic). Their tanks are supplied as original equipment to major truck brands and are known for durable construction, anti-corrosion protection and reliable performance in demanding air brake systems.

On this page you will find used OEM Frauenthal air tanks removed from late-model European lorries that we dismantle in Essex. Typical applications include DAF XF/CF Euro 6, MAN TGA/TGL/TGS/TGX, Mercedes-Benz Actros/Axor and Volvo FH/FM/FMX trucks, with popular sizes from around 7–10.5 litres up to 20–35 litres and working pressures commonly in the 12.5–15 bar range.

What Frauenthal parts you can find at VRA Truckparts

The Frauenthal brand on our site is focused on the air system and braking system. Here you will mainly see:

• Brake air tanks / reservoirs for service and parking brake circuits, often with capacity markings such as 7L, 8L, 10.5L, 15.3L, 20L or 25L and clearly shown pressure ratings.
• OEM Frauenthal tanks for DAF, MAN, Mercedes and Volvo, including popular references used on DAF XF106/CF Euro 6, MAN TGX/TGS, Mercedes Actros/Axor and Volvo/Renault platforms.
• Tanks with different port layouts and thread sizes (for example M22 x 1.5) so you can match the connections and orientation on your existing chassis.

For a broader view of everything we stock in this area, you can also browse our Used Truck Air Tanks & Air Brake Reservoirs category, where Frauenthal appears alongside other OEM suppliers.

Why choose Frauenthal air tanks from VRA Truckparts

• Genuine OEM quality: Frauenthal is a long-established specialist in air tanks for trucks, trailers and semi-trailers, with a very strong share of the European market for steel air tanks.
• Used, tested and inspected: we only list tanks removed from donor vehicles that built and held air pressure correctly; tanks with heavy corrosion or damage are rejected during dismantling.
• Clear part numbers and photos: each listing shows OEM numbers, capacity, pressure rating where known and detailed photos of ports and brackets, so you can visually compare with your existing tank.
• Fast UK and European shipping: we dispatch from Stanford-le-Hope, Essex with tracked parcel and pallet services across the UK and regular shipments to EU customers.

How to make sure you order the correct Frauenthal tank

Because air systems are safety-critical, it is important to match the replacement tank as closely as possible to the original. Before ordering from this Frauenthal brand page, we recommend that you check:

• OEM or Frauenthal part number stamped or printed on your current tank;
• capacity in litres (for example 7L, 10.5L, 15.3L, 20L, 25L or 35L);
• maximum working pressure (often 12.5 bar on modern European trucks);
• number, size and position of threaded ports around the tank circumference;
• bracket type – welded feet, saddle brackets or band clamps, and their orientation;
• truck brand, model, year and Euro class, as air system layouts change between generations.

If you are unsure which Frauenthal air tank fits your vehicle, please contact us with your VIN or registration number and clear photos of the existing tank and its label. You can also check our How to Find the Right Part and Compatibility & VIN Policy pages for more guidance.

Technical insight: Frauenthal air tanks in truck brake systems

In a heavy truck, the compressor builds pressure and feeds multiple air tanks. These reservoirs store compressed air for the service and parking brake circuits, as well as for air suspension and other pneumatic consumers. Correctly specified tanks help the system to build pressure quickly after start-up and maintain a stable pressure level during repeated braking and long descents.

Frauenthal specialises in steel and aluminium air pressure vessels designed specifically for commercial vehicles. Their production process combines advanced forming, welding and coating technologies to create tanks with robust weld seams and multi-layer internal and external corrosion protection, making them suitable for long-term use in harsh environments on truck chassis.

Typical Frauenthal applications on our stock vehicles

Many of the Frauenthal tanks in our warehouse come directly from factory-built braking systems on well-known European platforms. Current examples in the Air Tanks category include:

• DAF XF106/CF Euro 6 brake air tanks around 10.5L–25L, often rated to 12.5 bar and used in primary and secondary brake circuits;
• MAN TGA/TGL/TGS/TGX tanks in 8L, 20L and 35L sizes for various chassis positions;
• Mercedes-Benz Actros and Axor tanks around 20L for frame-mounted brake and auxiliary circuits;
• Volvo and Renault truck tanks used in modern FH, FM, FMX and T-series air systems.

Because these are original Frauenthal components from complete vehicles, they typically retain the exact port pattern, bracket layout and capacity required by the truck manufacturer, which helps avoid improvisation when you replace a corroded or damaged tank.

How we check and describe used air tanks

Every Frauenthal tank we list on this brand page has passed several steps in our internal process:

• The donor truck is run and checked where possible, to confirm that the air system builds and holds pressure correctly.
• During dismantling, technicians inspect the tank for severe external rust, dents, cracked welds, damaged threads and distorted brackets; suspect tanks are rejected.
• Accepted tanks are cleaned, labelled with OEM numbers, measured where needed and photographed from multiple angles so you can see the actual item on offer.

The description on each product page highlights key data such as capacity in litres, maximum working pressure (if known), main OE and Frauenthal references and which truck models the tank was originally fitted to. This information makes it easier to cross-check with catalogues or your workshop documentation.

Ordering and shipping Frauenthal air tanks

Most Frauenthal air tanks are compact enough to be shipped safely by parcel courier, while larger assemblies or combined orders may travel on pallets. Our checkout calculates shipping options and prices automatically, and we can advise on cost-effective delivery for multiple items. For more detail, see our Delivery & Shipping information.

Before placing an order, we recommend that you review:

• How to Order – step-by-step guidance on buying used truck parts from our online shop;

• Returns & Refunds and Warranty & Part Condition – our policies on part condition, guarantees and what to do if something is not as expected.

When a used Frauenthal tank is the right choice

For many workshops and fleet operators, a good used Frauenthal air tank is a smart alternative to buying new. You still get an OEM reservoir from a specialist European manufacturer, but at a fraction of the price of a brand-new part. This is particularly attractive when replacing tanks during routine maintenance, MOT preparation or repairs after corrosion has been spotted on the chassis.

By choosing a used Frauenthal tank from VRA Truckparts you also support the reuse of quality components and reduce waste, while keeping your trucks compliant and safe on the road.
