Pressure vessels and air receivers 15 l
15 l pressure vessels come in three horizontal versions: painted, with and without feet, for a working pressure of 11 bar, and stainless steel for 12 bar in AISI304 or AISI316L.
Fifteen litres serve as a small air reserve at a machine with sudden demand, in your own assembly or with a laboratory compressor, which is where the stainless steel version fits well. Compared with the 10-litre vessel, that is half as much air again. You will find other volumes and versions in our range of pressure vessels and air receivers.
What we offer in the 15 l size
All three vessels have the same diameter, and the painted ones also the same length. The stainless steel one is longer and withstands a higher pressure. You can compare the exact dimensions and connections on the vessels’ product pages.

The stainless steel vessel is made from two steels, AISI304 and AISI316L. Both versions have the same dimensions.

Fifteen litres where the length is fixed
A horizontal vessel often has to fit between two fixed obstacles, such as between the legs of a workbench or into a machine frame. When the 10-litre vessel is not enough, the painted 15-litre one holds half as much air again while being almost the same length, just wider.
The stainless steel 15 l vessel is longer than the painted one. If you are choosing between them for a fixed frame, compare the diameter and length on the product pages with the space you have.
Mounting without vibration
You bolt the painted vessel with feet to the frame or tabletop through the holes in its feet. The vessel without feet is placed in a frame or cabinet and held in clamps. Put a rubber insert between the clamp and the shell so that machine vibration does not rub off the paint.
The stainless steel vessel stands on two saddle feet. A small vessel is easily set vibrating, so rubber vibration dampers belong under the feet. It is not rigidly anchored to the floor or to any structure.
Paint or stainless steel
A blue RAL 5015 powder coating protects the painted vessels on the outside; inside, the steel remains bare. Such vessels belong in dry, heated rooms and are manufactured to Directive 2014/29/EU on simple pressure vessels (SPVD).
The stainless steel 15-litre vessel for 12 bar is manufactured to Directive 2014/68/EU (PED) and suits compressed air, nitrogen and air with water. It is pickled and passivated inside and out, with no coating. For environments with chlorides, choose the AISI316L version.
Both the painted vessels and the stainless steel one suit a compressor with a cut-out pressure of up to 10 bar, and the safety valve must open at no more than the vessel’s working pressure. The types of inspection and their intervals are set by national regulations. What applies in the Czech Republic is summarised in our article on operator obligations.
Where next
The 15-litre size sits between the trio of 10-litre vessels and the wider choice at 24 l. The other pages group the vessels by pressure, mounting, finish and directive.

Ventilek’s tip
Measure the diameter, not the length. The painted 15-litre vessel is only slightly longer than the 10-litre one, but noticeably wider. It is the width that decides whether it fits between the legs of a table or into a frame.
- Will a 15 l vessel fit in place of a 10-litre one?
- In length, the painted 15-litre vessel is almost the same, but it has a larger diameter. So compare mainly the diameter on the vessel’s product page with the space you have.
- What pressure are 15 l air receivers rated for?
- The painted ones for 11 bar, the stainless steel one for 12 bar. The compressor must not deliver a higher pressure into them than the one on the data plate.
- How do I mount a 15 l vessel without feet?
- With clamps in a frame or cabinet. A rubber insert against vibration belongs between the clamp and the shell.
- How do AISI304 and AISI316L differ?
- AISI316L contains molybdenum, so it is more resistant to aggressive environments and chlorides. Both versions have the same dimensions.
Send us the dimensions of the space where the vessel is to go, and we will advise you which 15-litre vessel will fit.
