breathing airelectrically-poweredstationary

Designed with control systems that allow effective monitoring of operations: interstage pressure, oil level, internal cabinet temperature, and rotation direction sensor. Aluminum monoblock Forged steel “gooseneck” head Splash lubrication Forged aluminum connecting rods Main roller bearings Needle bearings on connecting rods 1st and 2nd stage cylinders in aluminum with hard nicasil coating Guide cylinders of the 2nd and 3rd stage in aluminum with hard nicasil coating 3rd stage cylinder in steel with special treatment Stainless steel intake and exhaust valves Stainless steel cooling tubes Separator after the 2nd and 3rd stage Safety valves after each stage Maxifilter filtration system Oil level sensor One of the key parts of the compressor: the motor transfers movement to the pumping unit via the belt. This model is available with a single-phase or three-phase electric motor from 4 to 5.5 kW. The Maxifilter purification system ensures reliable treatment of breathing air according to DIN EN 12021¹ when original filter cartridges are used. Positioned after the compressor’s final separator and before the pressure maintenance valve, it features a separator after the 2nd and 3rd stage to create a first essential barrier against humidity. The filtration capacity with air inlet at 20 °C and 200 bar is 620 m³. ON/OFF switch with motor protection. Electromechanical pressure switch that stops the compressor at the final pressure. Drainage of all separators between individual stages and of the final separator during compressor operation. Timer for automatic condensate drainage.
