If you work with an air compressor, you may have heard about air receivers but do you really need one? What is its purpose, and how can it benefit your workplace?

Why Do I Need an Air Receiver?

One of the primary functions of an air receiver is to maintain a steady supply of compressed air to the system. This is achieved by storing compressed air during periods of low demand and releasing it during periods of high demand. This helps to reduce compressor cycling and prevent pressure fluctuations, which can damage equipment and lead to production downtime.

Another important benefit of an air receiver is its ability to remove moisture and contaminants from the compressed air. As air is compressed, it heats up and the moisture contained in the air condenses into liquid form. This water can accumulate in the air receiver and cause corrosion or damage to downstream equipment. An air receiver with a drain valve and proper maintenance procedures can help to remove this moisture and protect the system from damage.

Additionally, an air receiver can help to conserve energy by reducing the load on the compressor. By storing compressed air, the compressor can run at a lower capacity during periods of low demand, which reduces energy consumption and operating costs. This can lead to significant savings over the lifetime of the system.

What Air Receiver Do I Need?

When considering the purchase of an air receiver, it is important to take into account a variety of factors that will ultimately determine the appropriate size and type for your needs. The first step in this process is to assess your specific requirements and determine the maximum amount of air pressure and volume that will be necessary for your operations.

Once these requirements have been established, it is important to consider the physical space available for the air receiver and the necessary installation requirements such as access to electrical power and appropriate ventilation. The type of compressor that will be used in conjunction with the air receiver should also be taken into account, as different types of compressors produce varying volumes and pressures of air.

Another important consideration to keep in mind is the intended use of compressed air. Different industries and applications may require specialized air receivers, such as those with moisture removal or filtration capabilities, or those designed for high-temperature or high-pressure applications.

How Do I Size an Air Receiver Properly?

Firstly, it is important to consider the air consumption requirements of the system. This includes the maximum and minimum air flow rates, as well as any fluctuations in demand. It is also necessary to factor in the pressure rating of the compressor and the peak pressure requirements of the system.

Another key consideration is the volume of the receiver. This is determined by the required air storage capacity and the time needed to replenish the air supply. The receiver size should be large enough to accommodate the system’s demand while ensuring a sufficient reserve for peak demand periods.

In addition, the location and installation of the air receiver can affect its performance. It should be positioned in a well-ventilated area, away from any heat sources or contaminants. The installation should also allow for easy access for maintenance and inspection.
