DESCRIPTION
GENERAL DESCRIPTION
The Champion 330 is a valveless, pneumatically operated tool designed to utilize
Numa 32" to 48" (813 mm to 1219 mm) diameter bits in rock formations under a wide range
of operating conditions.
The Champion 330 hammer design incorporates a thick wall case. The non ported case
design allows for a large bore diameter in conjunction with optimum life against abrasion. The
simple design of the Champion 330 provides performance and dependability without sacrificing
tool life.
The Champion 330 is designed for universal applications using air pressure from 100 PSI
to 200 PSI (6.8 Bar to 13.6 Bar) with compressors having capacities of 3000 CFM (1416 Litres/
Second) or more. Depending on the hole size, rod size and rock conditions, additional hole
cleaning air or foam may be required. 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 10 to facilitate the
removal and the installation of the choke.
