Specifications are subject to change without notice.
 
NOTE: Numa RC hammers utilize an orifice "O" ring as a choke. Removal of the orifice "O" ring allows additional air to pass through the hammer for hole cleaning/flushing purposes.

NOTE: These figures are nominal. Conditional and circumstances such as choke size, altitude, ambient temperature, back pressure, formation etc. can and will alter these figures.
