DESCRIPTION
GENERAL DESCRIPTION
The Patriot 180 is a valveless, pneumatically operated tool designed to utilize Numa 18"
to 30" (457 mm to 762 mm) diameter bits in rock formations under a wide range of operating
conditions.
The Patriot 180 hammer design incorporates a non-reversible, hardened case. The single
bore design allows for a maximum bore diameter in conjunction with optimum life against
abrasion. The simple design of the Patriot 180 provides performance and dependability
without sacrificing tool life.
The Patriot 180 is designed for universal applications using air pressure from 100 PSI
to 250 PSI (6.8 Bar to 17.2 Bar) with compressors having capacities of 1350 CFM (637 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 15
for correct choke selection and pages 7 and 12 to facilitate the removal and the installation
of the choke. The Patriot 180 hammer is a high performance tool which may require additional
downfeed to maximize performance. Please contact your local Numa Representative for
further details.
