Smooths out pressure fluctuation
During sudden spikes in air demand, the receiver feeds the system with its stored air; pressure fluctuation at the compressor outlet is reduced.

Air Receivers (Carbon Steel / Stainless Steel)
Air receivers store compressed air from the compressor, smoothing out pressure fluctuation and preventing the compressor from cycling on unnecessarily; they also let part of the moisture in the air condense and separate out. At Denfor Endüstriyel, we supply air receivers in ST-37 carbon steel or stainless shells, together with a safety relief valve, pressure gauge and drain valve.

Why it matters
What does an air receiver do?
It stores compressed air from the compressor, smoothing out pressure fluctuations and protecting compressor life.
Shortens compressor run time
A sufficiently sized receiver lets the compressor run less often and for longer stretches, reducing fatigue from frequent start-stop cycling.
Helps separate out moisture
Some of the moisture in compressed air condenses inside the receiver and can be drained from the bottom discharge point, reducing the moisture load further down the line.
Safe operation with safety relief valve and gauge
Every receiver is supplied with a safety relief valve to keep it within its pressure limit and a pressure gauge to monitor the instantaneous pressure.
Types
Air receiver subtypes
All three store compressed air; what differs is shell material and area of use.
ST-37 carbon steel air receiver
The most widely used standard solution in general pneumatic systems and process lines, economical and durable.
- Economical solution
- General pneumatic systems
- Wide range of volumes
Stainless air receiver
Used in food and pharmaceutical facilities, on lines the compressed air contacts, to reduce the risk of corrosion and contamination.
- Stainless shell
- Suited to food/pharmaceutical facilities
- Corrosion resistance
Vertically or horizontally mounted air receiver
Supplied as a vertical (space-saving) or horizontal (low-height) shell option to suit the boiler room/compressor room layout.
- Mounting orientation to suit the layout
- Space-saving vertical option
- Horizontal option for limited headroom

FAQ
Questions from the field
The questions we encounter most often at the air receiver quote stage.
How is air receiver volume calculated?
It is calculated from the compressor's capacity, the system's instantaneous demand variation and the desired compressor run/stop duration; insufficient volume causes the compressor to cycle on and off frequently.
Should I choose carbon steel or stainless?
ST-37 carbon steel is sufficient and economical for general pneumatic systems; stainless should be preferred when the compressed air contacts a line requiring hygiene, such as food or pharmaceuticals.
Is periodic inspection required?
As pressure vessels, air receivers must undergo periodic pressure testing and inspection under the relevant regulations; this process matters for operating safety.
Should I choose vertical or horizontal?
A vertical model suits a compressor room with limited floor space, a horizontal model suits limited ceiling height; volume and fittings stay the same, only the shell orientation changes.
Do you only serve Istanbul?
No. While our office is on Istanbul's Anatolian side (Ataşehir), we supply and ship across Istanbul's European side, the surrounding provinces and the Marmara region, and Turkey as a whole — covering your equipment end to end, from a single source.
