Answer :
Sure! Let's carefully examine the range of pressures provided for operating pneumatic nailers and identify the most appropriate range:
1. 30 to 80 psi: This range appears to be too low for most pneumatic nailers, which typically require higher pressure to function effectively.
2. 60 to 110 psi: This range is closer but might be slightly on the lower side for the maximum pressure needed by some pneumatic nailers.
3. 70 to 120 psi: This range seems ideal as it covers both the lower and upper limits commonly required to operate pneumatic nailers efficiently.
4. 90 to 140 psi: This range starts too high and might exceed the recommended pressure range for many nailers, which could lead to equipment damage or safety issues.
Based on these observations, the most appropriate range for operating pneumatic nailers is:
70 to 120 psi
So, the correct answer is:
70 to 120 psi
