Halco Dominator 880DW

The Dominator 850 Deep-Well hammer has been specifically designed for drilling deep holes under a head of water. The one piece top-adaptor with N.R.V. (Non-Return-Valve) makes it easy to maintain and service the hammer. The wide body diameter of the Dominator 880 DW allows for an increased piston weight and therefore an improved performance. A variable choke for increased air volume can be fitted to the Dominator 880 DW to suit compressor volume outputs.

Suitable for operation at air pressures of 100 - 435 psi (7 - 30 bar).
Drilling diameters of 200 - 311 mm (7 7/8 - 12 1/4").
Available Shanks: IR DHD 380.
