The Bowen Jar Intensifier is completely safe to assemble, use and maintain, since no high pressure pre-loading is required.
The Intensifier is particularly valuable in deep, crooked holes where much of the stretch of the string is lost in friction. The tool is equally valuable at very shallow depths where very little stretch is available due to the short working string.
A secondary advantage of the tool is its ability to absorb much of the shock of the rebounding string after the jarring stroke, protecting tools and string from damage.
Full torque may be transmitted through Intensifier at all times, and full circulation may be maintained through the tool.
Operation of the tool is very simple, requiring only straight pull, as rapidly or as slowly as required by the operation.
