Steel and Galvanised Vertical Air Receivers

How to select the size of my receiver ?

Selecting the appropriate size for an air receiver is crucial for maintaining consistent air pressure and ensuring efficient operation of your air compressor system. While there's no one-size-fits-all approach, two general guidelines can help you determine the adequate size:

1. Based on Free Air Delivery (FAD)

Your air receiver capacity should be at least 25% of your free air delivery (FAD) expressed in cubic meters per minute (m³/min). This ensures that the receiver can accommodate a reasonable amount of compressed air before the compressor needs to engage again.

2. Based on Compressor's Motor Power

Another method is to calculate the receiver capacity based on the compressor's motor power in horsepower (HP). The formula is:

Receiver Capacity (L) = Motor Power (HP) * 30

For instance, if you're using a 10HP screw compressor, the minimum required receiver capacity would be:

Receiver Capacity (L) = 10 HP * 30 = 300 L

However, it's important to consider the specific application and usage patterns to determine the optimal receiver size. Factors like peak air demand, pressure fluctuations, and the number of air-powered tools or equipment connected to the system can influence the required size.

In general, larger air receivers offer better pressure regulation and can handle higher peak demands. However, they also come with a higher upfront cost and require more space. Smaller receivers are more compact and cost-effective, but they may not be able to handle sudden spikes in air demand without causing pressure fluctuations.

If you're unsure about the appropriate size for your air receiver, it's recommended to consult with a qualified compressed air specialist. They can assess your specific application and recommend the most suitable receiver size to ensure optimal performance and efficient operation of your air compressor system.
