Pressure vessels and air receivers 10 l
10 l pressure vessels and air receivers come in three versions, all of them horizontal: two painted ones for a working pressure of 11 bar, one with feet and one without, and a stainless steel one for 12 bar in AISI304 or AISI316L.
A 10-litre vessel works both with a compressor and directly at a machine, where it evens out the short bursts of demand of the pneumatic controls. Compared with the 5-litre one, it also has a connection on top of the shell, so the pressure gauge or safety valve sits clear of the condensate. Other sizes and versions are shown in the main category of pressure vessels and air receivers.
10 l vessels for air: mounting, material and pressure
All three vessels have the same diameter and length. They differ in how they are fixed in place, what they are made of and what pressure they withstand. You will find the exact dimensions and connections on the vessels’ product pages.

Among the small vessels, only the horizontal stainless steel 10 and 15 l vessels are rated for 12 bar; all other vessels up to 50 l are rated for 11 bar.

A vessel for a compressor or for a machine
On a machine with pneumatic controls, such as a press or a clamping device, a 10-litre vessel covers brief bursts of demand before the compressor can respond. In the air network, it also works well as a second, smaller vessel at a more distant workstation.
The stainless steel vessel is chosen for a smaller machine or a mobile air supply where clean air is needed. There is no coating inside that could peel off over time, and stainless steel resists corrosion from condensate. It serves for compressed air, nitrogen and air with water.
11 or 12 bar
The maximum pressure the compressor delivers into the vessel must not exceed the pressure on the vessel’s data plate. That is why both the painted vessels and the stainless steel one suit compressors with a cut-out pressure of up to 10 bar. Set the safety valve to no more than 11 bar on a painted vessel and to no more than 12 bar on the stainless steel one. The fittings and hoses you connect to the vessel must withstand the same pressure.
The painted carbon steel vessels are manufactured to Directive 2014/29/EU on simple pressure vessels (SPVD), the stainless steel one to Directive 2014/68/EU on pressure equipment (PED).
Condensate, documents and inspections
The top connection is for the pressure gauge or safety valve, the bottom one for draining the condensate. Water condenses from humid air inside the vessel and would eat away at a painted vessel from the inside, where the steel is bare. So drain it regularly, by hand or with an automatic condensate drain.
The vessel comes with a declaration of conformity and instructions for use and maintenance; the fittings are ordered separately. Whether, and how often, the vessel needs to be inspected is determined by national regulations according to its volume and pressure. You will find the details in our article on pressure vessel inspections.

If ten litres is not the right fit, look one size down or up. You will also find the stainless steel 10-litre vessel for 12 bar among the other vessels for the same pressure.

Ventilek’s tip
Mark the top connection before mounting. A cylinder without feet turns easily in its clamps, and the condensate connection then ends up on top, where the water cannot run out.
- What pressure can a 10 l pressure vessel withstand?
- The painted ones 11 bar, the stainless steel one 12 bar. Set the safety valve to no more than the pressure on the vessel’s data plate.
- Is a 10 l pressure vessel suitable for a compressor?
- Yes, for a compressor with a cut-out pressure of up to 10 bar. It enlarges the air reserve and evens out the pressure. How large an air receiver to choose is explained in our advice centre on choosing a pressure vessel.
- Does the 10 l vessel have a connection for a pressure gauge?
- Yes. All three have one connection on top of the shell, which is the right place for a pressure gauge or safety valve.
- What temperature can the 10 l vessel withstand?
- The painted ones −10 to +100 °C, and they belong in dry, heated rooms. The stainless steel one withstands −80 to +120 °C, but frozen condensate will block the drain even on it.
