An air receiver tank stores compressed air, smooths pressure pulsations and reduces compressor cycling. Choosing the right size and specification protects both the system and personnel.
The Role of the Receiver
- Buffers demand surges
- Reduces compressor start-stop cycling
- Lets moisture settle out
Sizing Rules of Thumb
A common guide is 3–5 gallons of storage per CFM of compressor output, with larger tanks for systems with big intermittent air demands.
Pressure Rating and Certification
The tank must be rated above the system maximum pressure and carry the local pressure-vessel certification. Check the relief valve and drain are functional.
Installation Notes
- Install vertically or horizontally per design
- Fit a safety relief valve and automatic drain
- Inspect for corrosion on schedule
