On today’s market, you have a choice of two main types of industrial rotary compressor – vane and screw. Although both are designed to produce the same output, they differ considerably in terms of energy efficiency. Here, we give you the low down. .
How they work – A rotary-vane compressorcomprises a rotor, with slots along its sides which house individual sliding vanes. This assembly is offset within a cylinder, or ‘stator’, and rotates on white-metal bushes. As the rotor turns on its axis, the vanes. .
Vane compressors typically run at lower speeds than relatively leaky screw machines. For example, Mattei’s fixed-speed Maximaoperates at 1,000rpm, versus the average screw compressor’s 3,000rpm or higher. Rotary-vane machines also have. .
How they work– A screw compressor has two parallel rotors which intersect along their sides. Replaceable roller bearings fitted into a stator maintain the rotors’ minimum clearance. During rotation, the intermeshing rotors compress the air. Their efficiency–.

Waterwell drilling is essentially drilling for underground water for agricultural and residential water needs. A perfect waterwell drilling setup would include: - A drill rig system which includes DTH hammer, DTH bit and drill tubes - Reliable skid mounted diesel air compressor.

When drilling a water well through the hard rock, no drilling method is as efficient as a DTH Hammer energized by the right air compressor providing high enough pressure. Softer grounds may also be drilled by air flushed rotary drilling, demanding a lower pressure air..
Air pressure requirement: The air compressor must provide sufficient air pressure to overcome the formation resistance encountered by the drill bit and maintain the drilling force. Typical air compressor pressures range from 7-30 bar (100-450 psi).
