SECTION I
DESCRIPTION
GENERAL DESCRIPTION
The Patriot 45 is a valveless, pneumatically operated tool designed to utilize Numa
TD40 4-1/2" to 5-1/4" (114 mm to 133 mm) diameter bits in rock formations under a wide
range of operating conditions.
The Patriot 45 hammer design incorporates a hardened reversible case. The single
bore design allows for a maximum bore diameter in conjunction with optimum life against
abrasion. The simple design of the Patriot 45 provides performance and dependability without
sacrificing tool life.
The Patriot 45 is designed for universal applications using air pressure from 150 PSI to
500 PSI (10.2 Bar to 34.5 Bar) with compressors having capacities of 335 CFM (158 Litres/
Second) or more. When drilling conditions require supplementary hole cleaning, additional
hole cleaning air can be passed through the hammer by utilizing an interchangeable choke.
All standard hammers shipped from Numa have a blank choke installed. Refer to page 11
for correct choke selection and pages 5 and 9 to facilitate the removal and the installation
of the choke.
