NBS90 SP Formulas
NBS 90SP transfers are actuated by a single air cylinder with a 2" bore and 1/2" stroke.
The air consumption per transfer is calculated by:
•
.0092CF (cubic feet) X CPM (cycles per min.) = SCFM (Standard Cubic Feet / Minute)
Adding together the air requirements of all transfers connected to one regulator will give total air flow
requirements for that NBS air system.
