Pressure vessels and air receivers 150 l
There are three 150 l pressure vessels, all for a working pressure of 11 bar: a horizontal air receiver in blue RAL 5015 paint and two stainless steel vessels, vertical and horizontal. The painted one is intended for compressed air, the stainless steel ones also for nitrogen and compressed air with water.
As a compressed air tank, the 150 l volume fills the gap between 100 and 200 l. It suits situations where one hundred litres is not enough and a larger vessel would not fit. Neither a vertical painted vessel nor a ready-made fittings kit is made in this size. You will find the other volumes and versions in our overview of pressure vessels and air receivers.
150 l pressure vessel: three options
All three vessels have the same volume and pressure; they differ in orientation and material. You will find the dimensions and connections on each vessel’s product page.
| Pressure vessels 150 l | |||||
|---|---|---|---|---|---|
| Vessel or kit | Design | Finish | Working pressure | Medium | Category |
| Horizontal pressure vessel 150 l - 11 bar | horizontal with feet | paint | 11 bar | air | Vessels from 100 to 720 l |
| Horizontal stainless steel pressure vessel 150 l - 11 bar | horizontal with feet | stainless AISI304 or AISI316L | 11 bar | air, water or nitrogen | Stainless vessels |
| Vertical stainless steel pressure vessel 150 l - 11 bar | vertical | stainless AISI304 or AISI316L | 11 bar | air, water or nitrogen | Stainless vessels |
The painted vessel is made only in a horizontal design and only in blue RAL 5015 paint; neither a galvanised nor an ALM-coated version is made in this volume. Both stainless steel vessels are made of AISI304 or AISI316L steel.

Horizontal 150 l air receiver in RAL 5015 paint
The horizontal vessel stands on two feet and is low, so it fits where there is room lengthways but not in height: next to the compressor, under a platform or in a rack. On the outside, it is protected by a powder coating; inside, the steel is bare, so it belongs in dry, heated rooms.
It serves as a reservoir for a piston compressor in a workshop or as a second vessel at a more distant workstation. Its connections are the same as on the horizontal 100 l vessel, so switching to the larger volume does not require any new pipe fittings.
There is no ready-made fittings kit for this vessel, so the parts are chosen individually: a safety valve set to no more than 11 bar, a pressure gauge, a shut-off valve and a condensate drain. By hand, the draining is done with a small drain valve, and unattended with an automatic condensate drain.
Stainless steel 150 l pressure vessel, also for air with water
The stainless steel vessels VVS150-11 (vertical) and VHS150-11 (horizontal) are made entirely of stainless steel with no coating, pickled and passivated inside and out. They are intended for compressed air, nitrogen and compressed air with water, that is, for group 2 fluids, and are manufactured to Directive 2014/68/EU (PED).
AISI316L steel contains molybdenum and is more resistant to aggressive environments and chlorides; AISI304 is sufficient where the vessel will not come into contact with such an environment. In this volume, both steels have the same dimensions and connections. The working temperature is −80 to +120 °C, so the vessel can also withstand frost.
The vessels are supplied without fittings. To keep the entire pipework in stainless steel, choose a stainless steel safety valve, pressure gauge and shut-off valves for them. Put rubber vibration dampers under the feet; wooden blocks under stainless steel hold moisture.
Which 150 l vessel to choose
For ordinary compressed air in a dry workshop, the painted vessel is enough. Stainless steel makes sense where air purity matters, where the vessel holds compressed air with water or where it stands in an aggressive environment. Whether a volume of 150 l will be enough for you can be worked out with the help of our advice centre on choosing an air receiver.
The painted vessel is manufactured to Directive 2014/29/EU on simple pressure vessels (SPVD), the stainless steel ones to the PED. Inspections and their intervals are set by national regulations according to the vessel’s volume and pressure; you will find what applies in the Czech Republic in our article on pressure vessel inspections.
Neighbouring volumes and similar vessels
If a volume of 150 l is not the right fit, look one step down or up, or at all horizontal, stainless steel or 11-bar vessels.

Ventilek’s tip
Give the horizontal vessel a slight fall. A few millimetres towards the condensate connection are enough, and the water collects where you drain it.
- Is there a vertical 150 l pressure vessel too?
- Yes, but only in stainless steel. The painted 150 l vessel is made in a horizontal design only.
- Is the 150 l pressure vessel suitable for water?
- For compressed air with water, yes, but only the stainless steel ones, vertical and horizontal. The painted horizontal vessel is intended for compressed air.
- What pressure are the 150 l vessels rated for?
- All three for 11 bar, so they suit compressors that cut out at no more than 10 bar.
- Is there a fittings kit for the 150 l vessel?
- There is no ready-made kit for this volume. You choose the safety valve, pressure gauge, shut-off valve and condensate drain individually, with the valve set to no more than 11 bar.
- How do AISI304 and AISI316L differ?
- AISI316L contains molybdenum, so it is more resistant to chlorides and aggressive environments. For the 150 l vessels, both steels have the same dimensions and connections.
