Root Blowers – Type & Operations

The Roots Blower is basically an upright drill that has a spinning cylinder that rotates horizontally. Unlike drillers that use a spindle or plate for the rotating action, the Root Blowers uses a horizontal rotating shaft and the result is a powerful drill that can be used both by hand and with power drill operators. The rotational movement of the shaft propels the drilling fluid into the bore hole. This action results in a high degree of efficient drilling, faster speeds, and reduced drilling wear and tear. The operation is simple – just pump the water into the bore hole and you are ready to drill.


The twin lobe roots blower consists of a horizontal shaft with a set of parallel meshed cylinders arranged in a rotary pattern. The shaft is controlled by a counter-rotating gear ration and this design of the Root Blowers ensures maximum efficiency, low running cost, and excellent power transfer. The fluids pumped into the bore holes are trapped inside the cylinder and transported to the output side via a displacement rotor. These roots blowers use an air tank and a fan to blow compressed air through the tubes and into the bore holes.


In the United States the most common type of Root Blowers is powered by a vertical-feeder system that is operated on a vertical shaft. It is generally smaller than other Roots Blowers available in the market and it may have a capacity of about five cubic feet per minute of air flow. Compared to other devices, this particular Root Blowers is less energy-inefficient and uses much more energy when it comes to power generation. It is important to note that with the exception of a few special models, power generation by Roots Blowers is directly proportional to the size of the blower.
