Product overview
Oil-free scroll air-ends — 3.7 and 5.5 kW families from Hanbell Precise Machinery
Hanbell's oil-free scroll catalog lists 3.7 kW and 5.5 kW air-ends. The orbiting scroll, fixed scroll and housing form the compression mechanism, while the compression chamber is separated from the lubricated transmission. The published design uses an integral centrifugal fan for cooling.
For the 5.5 kW air-end, the model table gives two separate working points. At 8 bar it lists 3,000 rpm and 600 L/min air flow; at 10 bar it lists 2,500 rpm and 440 L/min. The corresponding listed power readings are 5.78 kW and 6.5 kW. The nominal family designation therefore should not be treated as the actual input power at every pressure.
The same table records ambient temperatures of 21 °C and 27.1 °C and discharge temperatures of 172 °C and 205 °C respectively. These are associated table conditions, not universal operating limits. The pressure and flow data here apply to the 5.5 kW example; they should not be transferred to the separately listed 3.7 kW family.
For a complete package, specify the selected air-end, required pressure and air flow, duty cycle, cooling arrangement and downstream air treatment. Oil-free construction alone does not establish a certified air-quality class, dew point or suitability for a particular medical or food-production process.
