AIR CONSUMPTION
The SP50 requires 1.75 cubic feet per minute of free air to operate at the rate of 100 staples
per minute, at 55 p.s.i.
Take the actual rate at which the plier will be run to determine the amount of air required.
For instance, if your staple usage averages 50 staples per minute, you need 50% of the
7.75c.f.m. which is required for running at 100 staples per minute.
