Vertical pressure vessels and air receivers
Vertical pressure vessels for compressors from 24 to 10000 litres — 89 vessels from nine categories on one page. You will find standard air receivers for 11, 12 and 16 bar, fully equipped and stainless steel vessels, vacuum vessels for vacuum down to −1 bar, oxygen vessels, vessels rated for frost down to −20 °C and high-pressure vessels for 32 and 42 bar.
Of all the designs, a vertical vessel takes up the least floor space but needs height, so it suits a spot next to the compressor or a compressor room with little floor space to spare. You will find horizontal vessels and the other designs in our overview of pressure vessels and air receivers.
Nine categories of vertical vessels
Each row is one category: how many vertical vessels from it the page lists, in which volumes, for which pressure and with which finish. The dimensions and connections are on the vessel product pages.
| Vertical pressure vessels by category | ||||
|---|---|---|---|---|
| Category | Items | Volumes | Working pressure | Finish |
| Vessels down to −20 °C and for group 1 fluids | 20 | 1000–10000 l | 8 bar, 12 bar or 16 bar | paint, hot-dip zinc, ALM |
| High-pressure vessels for 32 and 42 bar | 19 | 100–5000 l | 32 bar or 42 bar | paint, hot-dip zinc |
| Stainless vessels | 11 | 24–3000 l | 11 bar | stainless AISI304 or AISI316L |
| Fully equipped vessels with fittings | 9 | 100–3000 l | 11 bar or 12 bar | paint, hot-dip zinc |
| Vessels from 1000 to 3000 l | 8 | 1000–3000 l | 12 bar or 16 bar | paint, hot-dip zinc, ALM |
| Vessels from 100 to 720 l | 7 | 100–720 l | 11 bar or 16 bar | paint, hot-dip zinc, ALM |
| Oxygen vessels | 7 | 500–5000 l | 11 bar or 12 bar | white RAL 9010 paint, ALM inside |
| Vacuum vessels | 6 | 100–3000 l | −1 bar (vacuum) | paint |
| Small vessels up to 50 l | 2 | 24–50 l | 11 bar | paint |
For carbon steel vessels, you choose paint, hot-dip zinc or the ALM coating as a version directly on the product page, but not every size is made in all three. Small and vacuum vessels are painted only, oxygen vessels have white RAL 9010 paint and ALM inside, and stainless steel vessels have no coating.

When a vertical air receiver makes sense
Space is what decides. A vertical vessel stands on a small footprint, so it fits even where a horizontal vessel of the same volume would be in the way. Before you order, however, measure the ceiling height and the doorways you will carry the vessel through, and leave room above the top end for the fittings and for servicing.
From 4000 to 10000 l, our range includes vertical vessels only, and all fully equipped, vacuum, high-pressure and oxygen vessels and the vessels rated down to −20 °C are vertical too. The smallest volumes of 5, 10 and 15 l, by contrast, are horizontal only.
Choose the volume according to the compressor output and how much the air demand fluctuates. How to calculate it is shown in our advice centre on choosing and connecting an air receiver.
Standard air receiver or a vessel for special applications
For compressed air from a standard compressor, a painted vessel is all you need; from 100 l, there is also a galvanised version, and from 270 l usually one with the ALM coating as well. A fully equipped vessel is the same air receiver with ball valves, a pressure gauge and a 10.5 bar safety valve already mounted; it comes with TÜV certification of the pressure assembly and belongs with compressors with a cut-out pressure of up to 10 bar. For standard stand-alone vessels from 100 to 3000 l for 11 and 12 bar, there are ready-made fittings kits with the same parts, KVP for a painted and KVG for a galvanised vessel.
Stainless steel vessels in AISI304 or AISI316L have no coating, are pickled and passivated and can also take water and nitrogen. The vessels rated down to −20 °C can get through the winter outdoors or in an unheated hall, and together with the high-pressure vessels for 32 and 42 bar they can also hold group 1 fluids: besides air and nitrogen, argon, helium, oil and oxygen, but not hydrogen. The oxygen series has white RAL 9010 paint on the outside and an ALM epoxy coating on the inside.
Vacuum vessels from 100 to 3000 l hold a vacuum reserve down to −1 bar next to a vacuum pump or in a vacuum network. They are made to the EN 286-1 standard, and positive pressure does not belong in them.
Pressure, finish and regulations
The pressure on the vessel’s data plate must be at least as high as the compressor’s maximum pressure: compressors up to 10 bar need an 11-bar or 12-bar vessel, compressors above 10 bar a 16-bar vessel, and high-pressure compressors a 32-bar or 42-bar vessel. The 8-bar vessels are intended for lower-pressure systems.
RAL 5015 paint protects the vessel only on the outside; inside, the steel stays bare, which is why a painted vessel belongs in dry, heated rooms. Hot-dip zinc covers the steel inside and out and copes with damp, and the ALM epoxy coating on the inside is approved for contact with food.
Fourteen vertical vessels up to 720 l comply with the SPVD Directive 2014/29/EU on simple pressure vessels, 69 large, stainless steel, high-pressure and oxygen vessels with the PED Directive 2014/68/EU, and six vacuum vessels with the EN 286-1 standard, with no CE marking. Inspections and their intervals are set by national regulations according to volume and pressure; for the Czech Republic, they are covered in our article on operator obligations.

Ventilek’s tip
Drain the condensate from the bottom end. The lowest point of a vertical vessel is the connection in the bottom end. That is where a drain valve or an automatic condensate drain belongs; water cannot be drained from the side connections.
- Which vertical air receiver should I choose for my compressor?
- For a compressor up to 10 bar, a painted vessel for 11 or 12 bar; for a damp compressor room, a galvanised one. If you do not want to source the fittings yourself, take a fully equipped vessel.
- What is the largest vertical air receiver you offer?
- Ten thousand litres. The three vessels of this volume are rated for 8, 12 or 16 bar and withstand frost down to −20 °C.
- Do you have a vertical air receiver for vacuum?
- Yes, six vacuum vessels from 100 to 3000 l for vacuum down to −1 bar, made to the EN 286-1 standard. They are not suitable for compressed air.
- Does a vertical vessel have to be bolted to the floor?
- No. Vibration dampers belong under the foot plates, and the vessel is not rigidly anchored to the floor or to any structure, so that vibration from the compressor does not stress the welds.
- Are there stainless steel vertical vessels too?
- Yes, eleven stainless steel vessels from 24 to 3000 l for 11 bar, in AISI304 or AISI316L steel.
