Screw compressors SiloKing 700 by German manufacturer CVS Engineering GmbH are designed for unloading of loose foodstuffs and chemicals form silo trucks by compressed air.

Compressors of capacity up to 700 m³/h are used for blow-out of loose powdery materials of small granulation (in which the air does not escape among the grains) and where pressure of 1 to 2,5 bar is required. Most often they are applied for blow-out of cement, salt, chalk, lime, flour, groats etc. An unquestionable advantage of this compressor is its all-metal structure as well as the 8.5 l of oil to cool the crankcase, which significantly increases the service life of a compressor. Options include a complete assembly with direct drive, heat exchanger for air and electric motor. For details see technical specification cards for this product.
