Single Stage Single-stage types are designed according to 8 bar pressure, two-stage types are designed according to 15 bar pressure and high-pressure types are designed according to 25-30 bar pressure. It is driven by V belt-pulley. Preferable as a chassis unit without air tank Preference to be able to start with mono-phase electric motors for the types with power up to 4kW Compressor is driven with F proof, IP55 protected, IE2 efficiency asynchronous electric motor. Compressor block and cylinders are casted from grey iron EN GJL250 material and the crankshaft is casted from ductile iron EN-GJS 500-7 material. Splashing lubrication is made with the help of a bar which is integrated into the design of the crankshaft. There is a mini ball valve integrated to the body, enabling easy evacuation of compressor oil. Outlet of this valve is fitted with a removable blind plug against the risk of discharged oil.

Brand Services represents German KOHO company in Poland. German KOHO company supplies the piston gas compressors on Polish market. Construction: Verctical construction, non lubricated, reciprocating process gas compressors The advantage of vertical type is the extended life time of piston rings and the less wear of cylinder liners, because the weight of the piston do not burden the piston rings. Media: Hydrocarbons, noble gases, exhaust vapours, pure hydrogen, nitrogen and all process gases, even very agressive hydrosulphides with the exception of pure oxygen and acetylene.
