Compressed Air Tanks

Compressed Air Tanks

Compressed Air Receivers (tanks) are critical components in compressed air systems. They act as storage vessels and buffers between the air compressor and the point of use, helping manage air flow, reduce compressor cycling, and improve efficiency and stability in the system. At John Henry Foster, we offer a variety of compressed air tanks for any application.

Function of an Air Compressor Receiver
An air compressor receiver tank, also known as an air storage tank, plays a critical role in the overall performance and efficiency of a compressed air system. Its primary function is to store compressed air for future use, helping to smooth out demand fluctuations and ensure a consistent supply during peak usage periods. 

Receiver tanks also aid in pressure stabilization, maintaining steady system pressure, and reducing the risk of pressure drops that can impact equipment performance. By minimizing the frequency of compressor starts and stops, they contribute to longer compressor life and improved energy efficiency. Additionally, these tanks assist with condensate management, allowing moisture and oil to naturally settle before the air moves downstream. As an added safety benefit, receiver tanks act as a buffer against pressure surges, protecting downstream tools and components from sudden spikes.
Types of Air Receivers
There are two common types of air receivers used. These include:

Wet Receiver

A wet receiver is installed upstream of the air dryer, directly after the compressor. Its primary function is to cool the hot, compressed air as it exits the compressor, allowing moisture, oil, and particulate matter to condense and settle at the bottom of the tank before the air enters the dryer. This process not only improves the efficiency and lifespan of the dryer but also reduces the moisture load, making overall air treatment more effective. By acting as a first-stage buffer, the wet receiver helps stabilize system pressure and provides a cleaner air stream for downstream filtration and drying.
 
Dry Receiver

A dry receiver is located downstream of the air dryer and is used to store clean, dry compressed air before it reaches points of use. This tank acts as a pressure reservoir, ensuring consistent air delivery even during peak demand or when multiple tools and machines are drawing air at once. By maintaining a steady pressure and minimizing fluctuations, the dry receiver helps protect sensitive equipment and enhances system responsiveness and reliability. It’s essential for applications that require high-quality, moisture-free compressed air at all times. 
Sizing Guidelines

The size of the compressed air tank you select depends on:

  • Compressor capacity (cfm)

  • System pressure

  • Application (steady vs. fluctuating demand)


As a general rule of thumb, typical systems need a receiver size (in gallons) that is one to three times the compressor’s cfm output.
