  Recommended Air Compressor Specifications

 • HP: 1 1/2 HP or greater.

 • Compressor Rated at 150 PSI Max. or greater.

 • Accumulator Tank Capacity: 4 Gallons or greater

 • Pressure Regulator: Set operating pressure at 90 - 110 PSI.

 • SCFM @ 100 PSI: 4.6 CFM

 • Pressure Switch Trip On: 110 PSI (± 5)

 • Pressure Switch Trip Off: 135 PSI (± 5)

2. Filter-Regulator-Lubricator

  There should be an Air-Line Filter between the Pressure Regu-

lator and the Air Compressor to insure clean, dry air.  Filter on 

Air-Line must be drained after use every day. The Air Compres-

sor should have an air inlet filter.  The filter medium should 

be cleaned or replaced as needed or as recommended by the 

manufacturer of the filtration unit.  The air compressor must be 

equipped with a condensate drain at bottom of the accumulator 

tank. The accumulator tank should be drained after each day’s 

use. 

3. Air Hose

  3/8” ID is recommended. Air supply hoses should have a mini-

mum working pressure rating of 150 PSI (10.4 bar  10.6 kgf/cm2) 

or 150 percent of the maximum pressure produced in the power 

source, whichever is higher. 

4. Hose Coupling

  Any configuration of quick connect fittings with either a 3/8” 

NPT thread or a combination of a 1/4 NPT thread fitting and 3/8 – 

1/4 NPT reducer. The fitting must be capable of discharging tool 

air pressure when disconnected from the air supply.

5. Air Consumption

  The Tool requires 4.6 cubic feet per minute of free air to operate 

at the rate of 60 fasteners per minute @ 90 PSI.  Take the actual 

rate at which the tool will be run to determine the amount of 

air required.  For instance, if your fastener usage averages 30 

fasteners per minute, you need 50% of the tool’s CFM of free air 

which is required to operate the tool at 60 fasteners per minute.

6. Operating Pressure

  90 to 110 PSI  Select the operating pressure within this range for 

best fastener performance. DO NOT EXCEED 120 PSI.
