Grundomat® soil displacement hammers
Grundomat® are the world's best soil displacement hammers for pipe and fibre installation.
The Grundomat® design provides greater target accuracy than traditional pneumatic boring tools.
In just one simple step, the mole performs a bore and pulls in pipe behind it.
Minimal footprint avoids sizable surface damage and time consuming restoration.
Rotair petrol compressors
Rotair manufactures the VRK200 dual pressure compressor ideal for the Grundomat® tools. The VRK200 has settings for using the Grundomat® at 7 bar and blowing fibre at 13 bar(at 34CFM).
Running a honda v twin engine, the VRK200 is powerful but economical, providing high performance through consistency of pressure and the low maintenance of an industrial petrol screw compressor.
The VRK200 Compressor will service Grundomats from 45mm to 75mm and there are other options for larger sizes.
