Wet Storage
Receiver Before the Dryer
Helps cool air, collect condensate and stabilize compressor operation before treatment.
Compressed Air Storage Guide
Air Receiver Tank Sizing Guide
An air receiver stores compressed air, stabilizes pressure, supports short demand events and provides a place for condensate to collect. The correct size depends on airflow, usable pressure band, control strategy and the duration of the demand event.
Quick Answer
Air receiver sizing should be based on the CFM that must be supported, the allowable pressure drop and how long the receiver must supply that demand. Larger storage can reduce rapid cycling and pressure swings, but it does not replace adequate compressor capacity.
Key Concepts
Dry Storage
Receiver After the Dryer
Stores treated air close to the demand and can help protect pressure at the point of use.
Control
Usable Pressure Band
The difference between starting and minimum acceptable pressure determines how much stored air is usable.
Selection and Troubleshooting Guide
Practical Compressed Air Guide
| Condition | Recommended Starting Point | Why | What to Verify |
|---|---|---|---|
| Short high-flow event | Add receiver volume near the demand | Stored air supports the brief peak | Confirm the event CFM and duration. |
| Rapid compressor cycling | Increase storage and review controls | More volume slows pressure change | Also verify compressor sizing and control settings. |
| Pressure swings at one process | Consider local dry storage | Storage near the process reduces distribution lag | Check piping and regulator restrictions. |
| Water in receiver | Maintain aftercooling and automatic drain | Receivers collect condensate as air cools | Inspect drain and condensate treatment. |

Air Receiver Tank Sizing Guide FAQs
How do I size an air receiver tank?
Use the demand CFM, support duration and usable pressure band, then confirm the result against the complete system design.
What is the difference between wet and dry storage?
Wet storage is before the dryer; dry storage is after the dryer.
Does a larger receiver increase compressor CFM?
No. It stores air and supports short events but does not increase compressor production.
Can a receiver reduce compressor cycling?
Yes. Additional volume slows pressure change and can reduce rapid cycling when controls are set correctly.
Where should the receiver be installed?
Placement depends on whether the goal is compressor control, moisture collection or local process support.
Why does water collect in the receiver?
Compressed air cools in the tank, causing water vapor to condense.
