16. Want kind of a compressor is needed for my Grex pinner?

Most compressors today max out at 120 psi, which is more than sufficient for using your Grex pinner. Refer to your owner's manual for detailed instructions on operating your Grex pinner at the appropriate air pressure. All Grex pinners require very little air consumption, less than 2/1000ths of a cubic feet per cycle at any given operating air pressure. However, operating the tool at sufficient air pressures is much more critical. The typical operating range for your Grex pinner is 90 to 100psi. When driving pins longer than 1-3/8" the operating pressure must be maintained at 110psi. For harder woods, your Grex pinner can be operated at a higher air pressure. So when choosing an air compressor, the most important specification is the maximum pressure it can sustain. Although, the air consumption of your Grex pinners are low, choosing a compressor with a decent sized tank (about 2 gallons) is necessary to maintain the air pressure to the tool. The smaller the tank, the quicker the air pressure drops as you're using the tool. This is also dependent on the kick-in pressure set on the compressor. Make sure you can adjust the kick-in pressure so the compressor begins pumping again before the air pressure drops below the required operating pressure. Refer to your compressor’s owner’s manual for more information on your compressor’s settings.
