This is a calculation example for determining rough estimate of required receiver tank capacity.
Load and unload period (loading time + unloading time)
Example: In case of SGIV, t1+t2 ≧ 0.5 min ≧(30 seconds or more)
Discharge air flow of compressor
Suction absolute pressure (atmospheric pressure = 0.101 Mpa)
Difference between upper pressure limit (PH) and lower pressure limit (PL)
Load ratio (air consumption rate against discharge air flow of compressor on above Qs)
* The tank capacity becomes maximum when the load ratio is 50%.
Capacity of receiver tank

This is a calculation example for determining a rough estimate of how much air flow rate must be increased by installing additional compressors, to maintain higher pressure when a large amount of air consumption is reducing pressure.
V2 ≧ V1 × (
Current line pressure
Desired sustained level of pressure
Total air flow rate of existing compressors
Required air flow rate for additionally installed compressors
The maximum amount of water vapor in the air (amount of saturated water vapor) increases as temperature elevates and decreases as pressure elevates. Compressing air, therefore, causes draining of water.
Compressor operating time
Suctioned air temperature
Amount of saturated water vapor
Moisture content in the suctioned air (per m3/min)
Moisture content in the air suctioned by compressor
Atmospheric dew point (refer to below chart for conversion from pressure dew point)
Total moisture content in the output of dryer
