55kw electric explosion-proof screw air compressor uses 
 Developing coal mine tunnel and spray equipment, pneumatic tools required by the ground when the supply of compressed air, due to the pipeline length, pressure is reduced, so efficiency is very low. The air compressor can be near the safe operation of underground tunneling face, and move forward with the roadway extension, it can maintain a high pressure, so that aerodynamic efficiency of the machine than on the ground when the gas supply by 30% to 100 power down 30%, and can save a lot of pipes. The compressor also applies to use of roadway construction projects. 
 Feature 
 SKK host using advanced structure, the five of the six small gap between teeth tooth, so the return loss, to four of the six tooth efficiency 10-12%, saving 25%; and with high accuracy, smooth operation, noise low, high reliability, long life, low maintenance costs, low fuel consumption advantage. 
 Austria HOERBIGER company a full set of gas control system, stable and reliable. 
 0-100 load adjustment to the actual use of gas as much, automatically adjusts the moving rate of consumption. 
 Safety and reliability. With explosion-proof, overload, short circuit, phase, until the leakage protection; also has over-temperature, air filter clogging, oil filter clogging, clogged oil over-temperature alarm and shutdown until the protection device, as well as capacity control, the system pressure valve, safety valve triple protection against overpressure operation. Imported oil and gas separation filter ultra-fine glass fibers, the oil content of compressed air controlled at 3ppm or less.
