Figure 10. Compressed Air Requirements
To determine the compressed air requirements for a particular shear, use the information in the preceding cart and
multiply the cu. ft. of air required by the number of strokes per minute that the shear is to operate. The requirements, as
shown in Figure 10, are average, based on worn clutch and brake linings. New brake and clutch would require
approximately 40 percent less vol.
If a separate air compressor and tank is to be used for the shear, it should be capable of a minimum of 100 psi
discharge and should be equipped an "on-off' pressure switch to automatically maintain the required pressure.
