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.
It is air cooled: Cooling is ensured by the air flow generated by the flywheel fan through intercoolers and after-coolers.
Thanks to the sight glass integrated to the compressor head, condition of the oil can be easily traced.
Monitoring the pressure condition is maintained with a manometer.
Operation control (idle -loaded operation) is provided by the pressure switch. The system is provided with safeguards against excessive pressure with a safety valve set to +1 bar value of the compressor operating pressure.
Air filter element is introduced into a plastic filter cup allowing easy replacement.
Safety of the belt-pulley system is ensured with an enclosed housing in accordance with CE norms.
The compressor is started directly with motor protection switch up to 4 kW motor power types, and with star-delta control panel up to 5.5kW motor power types and more.
Air in the system is prevented from re-returning to the compressor with a one-way valve incorporated in the compressor system.
The compressor unit is mounted on the air tank.
The air tanks are designed and produced by us in accordance with the 2009/105/EC directive.
The air outlet on air tanks must be fitted with a ball valve. However, a mini ball valve is also used for the evacuation of condensation water under the tanks.
In case of sudden interruption and return of the power in the compressor, evacuation of air jammed between check valve and compressor is performed manually with a mini ball valve mounted under the collector. Such evacuation is carried out automatically with a 2/2 Y solenoid valve attached to the collector for 7,5kw and more engine power types.
